Buds

I’ve met people who thought that buds appeared in spring just before the leaves came out but no, buds actually form in late summer, when trees begin storing reserves to help them get through winter. The period is called lignification and it happens when trees stop their active growth cycle. One of the ways to identify trees and shrubs in winter is by their buds. The size and placement of buds as well as the number of bud scales (cataphylls) can all help with identification. Bud scales are modified leaves that cover and protect the bud through winter. Some buds can have several, some have two, some just one scale called a cap, and some buds have none at all. Buds that have several scales are called imbricate and have scales that overlap like shingles. I’m starting this post with some unusual trees that aren’t often seen in this area, and the bud shown above is a sweet gum bud. It is a good example of an imbricate bud. It is also a good example of a rarity here.

Sweet gum trees (Liquidambar styraciflua) are easily identified by their unusual seed pods, above, and by the large size of their buds, which can be green, red or orange. I’ve read that Native Americans used the hardened resin from these trees for chewing gum. The resin was also used in a tea to calm the nerves and, when powdered and mixed with shavings from the tree, was used as incense by the Maya. The resin is said to look like liquid amber, and that’s where the first part of the scientific name, Liquidambar comes from.

Another tree you’ll have a hard time finding in this area is the European copper beech (Fagus sylvatica purpurea.) I’ve looked at its buds before in March and maybe they were swelling up to prepare for bud break, but they seemed bigger than those on our native trees. This year in January they really don’t look much different than our native beech buds. Long and pointed, they are a different shape than the sweet gum bud we saw but are still imbricate buds because of their shingle like, overlapping bud scales. They’ll open with maroon foliage, which over time will become a beautiful bronze / purple.

I love the bark on this old beech tree. It reminded me of an elephant’s skin. This tree lives on the grounds of the local college and there is another in Dublin, but otherwise I don’t know of any other European beeches in this area.

Tibetan cherry (Prunus serrula Tibetica) is another tree you might have a hard time finding but if you had studied your buds, you would recognize these big, shiny red buds as more imbricate buds. A gummy resin often fills any spaces between the scales and makes the bud waterproof. If water ever reached the bud and froze it could kill or damage it, so nature found a way to prevent that from happening. The shape of many imbricate buds also ensures that water will run off, rather than stay on the bud. Bud scales also help prevent moisture loss. These buds are very pretty, in my opinion.

The bark of a Tibetan cherry is very interesting. It is also called the paper bark cherry because of the way its bark peels as it ages, much like a birch. It is used as an ornamental tree as much for its bark as for its flowers, which are similar in shape and size to other ornamental cherries. The mahogany bark has very long, closely spaced lenticels that give it an unusual appearance. Lenticels are corky pores that allow gases like oxygen to reach the living cells of the bark. Without enough oxygen bark can die, so it “breathes.”

The most unusual tree bud to appear in this post is that of the ginkgo, which I find at the local grocery store, of all places. The short shoots bear terminal buds that are small at less than an eighth of an inch, with room for just two overlapping scales. A bud with only two overlapping scales is called two ranked. You can see how the terminal bud and many leaf scars are crowded together. Ginkgo is considered a “fossil tree” that has been on earth for millions of years. It is also considered the oldest living seed plant. It is said to be capable of living several hundred years, and there are trees in China that are thought to be at least 400 years old.

Buds with two scales that meet but do not overlap are called valvate buds, and a good example of a valvate bud can be found on nannyberry shrubs (Viburnum lentago). Though the scales in the photo do happen to overlap somewhat normally they would not, so they are still considered valvate. Nannyberry is one of our few native viburnums with edible fruit. They can get quite tall, almost the size of a small tree. According to the book The Origins of English Words “nannyberry” is also called sheep berry and that name comes from its fruit, which is said to resemble sheep droppings. The nanny part of the name comes from the nanny goat. Squirrels and birds are said to eat the fruit but I see huge numbers of them still on the bushes well into winter.

Cornelian cherry buds (Cornus mas) are also good examples of valvate buds. In the spring when the plant begins to take up water through its roots the buds swell and the two scales part to let the bud grow. What confuses me about this shrub is how the two outer scales never seem to be completely closed. It doesn’t seem to matter though because they always flower beautifully. Some bud scales like these are hairy and some are covered with sticky resin that further protects the bud. Cornelian cherry is an ornamental flowering shrub related to dogwoods. It blooms in early spring (in March) with clusters of blossoms that have small, bright yellow bracts.

One bud scale covering a bud is called a cap, and magnolia bud scales are good examples of that. Magnolia flower buds are described as “densely pubescent, single-scaled, terminal flower buds” and that’s what we see here. The hairy single scale will fall off when the bud inside has swollen to the point of blossoming. Once the plant flowers the ground under it will be littered with these hairy caps for a short time, so if you’d like to see one up close that’s the time to look.

I was lucky to find a seed pod on the magnolia that I looked at but unfortunately it was quite dry. I’d like to find a fresh one because I’ve read that they’re full of bright red seeds. I’ll look for one this spring to show you.

Big, black and pointed mountain ash buds (Sorbus americana) fooled me into thinking they had a single cap like bud scale at first, but they actually have several overlapping scales which are quite sticky. I finally got a photo that shows this. You have to look closely at buds to see what is really going on, so it helps to have a loupe or a macro lens.

The terminal buds on a Colorado blue spruce (Picea pungens) are oval shaped and imbricate with many bud scales. Sometimes the scales pull back from the bud (reflex) as these did, creating what look like tiny green flowers. In a way they remind me of the male flowers on a haircap moss, but of course they’re much bigger.

Here is a look at the side of the bud in the previous photo. Evergreen buds can be very sticky, but I’ve noticed that much more sap or resin flow occurs on warm days. On a cold day in January these buds were hardly sticky at all. You can also see the rows of whiteish breathing pores (stomata) on some of the needles in this shot. Carbon dioxide, oxygen, and water vapor enter and exit the tree through these tiny openings. There are many millions of them on a single tree.

If you see that some of the branches on your Colorado blue spruce are a bit deformed like those seen in the above photo your tree has the Eastern spruce gall adelgid living on it. They cause crab claw like galls but don’t do any real harm to the tree. I’ve had them on a tree in my yard for years now and it is still as healthy as the day I planted it. By the way, a blue spruce can be green.

If I had to choose a favorite tree bud the flower buds of the red maple (Acer rubrum) would have to be at the top of the list. They’re very beautiful but more than that, they are one of my first signals that spring has finally come. It doesn’t matter what the calendar says, when I see red maple flowers, I know winter is over. Of course sometimes they get a little over anxious and will get frost bitten, but more often than not they’re a reliable indicator. Each small flower bud has four pairs of bud scales.

Sugar maple terminal buds (Acer saccharum) appear on the end or terminus of a branch. The larger, pointed, very scaly bud is flanked by lateral buds on either side. The lateral buds are usually smaller than the terminal bud and the twigs and buds are brown rather than red like silver or red maples. These buds have imbricate bud scales and they show the whitish, sticky resin that “glues” one scale to another.

Norway maple (Acer platanoides) buds are also imbricate but instead of sticky resin on the edges of its bud scales they have a fringe of fine hairs which help shed water. These buds are relatively large and easy to study using a hand lens, so they’re perfect for children in the field.

Buds that have no bud scales but are very hairy like those seen on witch hazel (Hamamelis virginiana,) are called naked buds. The hairs take the place of bud scales when it comes to protecting the bud and it works well. Other naked buds are found on staghorn sumacs (Rhus typhina) and the native viburnum called hobblebush (Viburnum lantanoides).

Witch hazel flower buds are also very hairy, but rounder than its leaf buds. It won’t be long before the yellow or orange strap like flower petals appear on the spring witch hazels. It’s something I’m impatiently looking forward to.

I know that not everyone gets as excited over buds as I do but I also know that there are children who read these posts so I often have them in mind when I do a post like this one. I hope something like a post on buds might help jump start a child’s interest in nature. They aren’t that complicated and hopefully bud scale terminology won’t seem too intimidating.

If you are interested in learning about tree and shrub buds, start with one in your own yard that you are sure of, like a maple tree or even your rhododendron, and then branch out to those you don’t know well. The following information might help to get you started:

A bud scale is made up of modified leaves or stipules that cover and protect the bud in winter. Usually the number of bud scales surrounding a bud will help identify a tree or shrub.

Imbricate bud: A bud with numerous scales that overlap each other like shingles.

Valvate bud: A bud with two or three scales that do not overlap.

Two Ranked Bud: A bud with two scales that do overlap.

Caplike bud: A bud with a single scale that comes off in the spring.

Naked bud: A bud with no scales.

If you find that you have the itch to learn even more about buds and trees, this little book is for you. I’ve had my copy since I was a teen but it’s still in print. It is very helpful and easy to understand.

Must we always teach our children with books? Let them look at the stars and the mountains above. Let them look at the waters and the trees and flowers on Earth. Then they will begin to think, and to think is the beginning of a real education.  ~David Polis

Buds

You’ve seen a lot of buds on this blog but you haven’t seen many buds from a sweet gum tree (Liquidambar styraciflua). Massachusetts is the northern limit of their natural range but luckily I know a spot at the local college where two or three trees can grow thanks to the radiant heating they get from a massive wall of brick that they grow beside. As buds go these are big; this one was maybe the size of a blueberry, and may be green, red or orange, from what I’ve read. Buds with many scales that overlap like shingles are called imbricate buds. A gummy resin often fills the spaces between the scales and makes the bud waterproof on northern trees, but I’m not sure how the sweetgum buds waterproof themselves. I can see tiny hairs at the edge of the scales, so maybe that has something to do with it.

The identification of the sweetgum trees came easily because of their strange seed pods. I’ve read that Native Americans used the hardened resin from these trees for chewing gum. The resin was also used in a tea to calm the nerves and, when powdered and mixed with shavings from the tree, was used as incense by the Maya. The resin is said to look like liquid amber, and that’s where the first part of the scientific name, Liquidambar, comes from. I’d love to see it but I doubt the local college would let me tap their trees.

Bud scales are modified leaves that cover and protect the bud through winter. Some buds can have several, some have two, some have just one scale called a cap, and some buds are naked, with none at all. The lilac bud (Syringa vulgaris) in the above photo is another good example of an imbricate bud. I was surprised by the lack of gummy resin on these buds. I hope the flower or leaf buds inside aren’t harmed because of it.

The hairy, two part valvate bud scales of the Cornellian cherry are always open just enough to allow a peek inside. The gap between the bud scales will become more yellow as the season progresses and finally clusters of tiny star like yellow flowers will burst from the bud. These buds are small, no bigger than a pea. Cornelian cherry is an ornamental flowering shrub related to dogwoods. It blooms in early spring (usually March).

Magnolia flower buds in botanical terms are “densely pubescent, single-scaled, terminal flower buds.” The hairy single scale is called a cap and it will fall off only when the bud inside has swollen to the point of blossoming. Just as the plant flowers the ground under it will be littered with these hairy caps for a short time.

Many plants protect their buds with hairs, like the staghorn sumac (Rhus typhina) shown above. Plants that protect their buds in this way have naked buds, and the hairs take the place of bud scales.  

Red oak (Quercus rubra) buds usually appear in a cluster and are conical and reddish brown. I like the chevron like pattern that the bud scales make. Red oak is one of our most common trees in New England but in the past many thousands were lost to gypsy moth infestations. It is an important source of lumber, flooring and fire wood. The USDA says that red oaks can live to be 500 years old.

Do you think of buds when you see a catkin? A catkin is really just a long string of tiny flowers arranged in a spiral, surrounding a central stalk. Though the bud scales on many of the male alder catkins (Alnus incana) are usually a deep winter purple, this year they seem to be more red. That doesn’t matter because soon they will start to lengthen and become more pliable before turning shades of pink, orange, red and brown. Once that happens they will start to open.

There is no mistaking what you’re seeing when male alder catkins start to open. The bud scales are on short stalks, and when they open they reveal the tiny green yellow flowers they have protected all winter long. Bushes full of them are easily one of the most beautiful spring sights.

Each bud scale has three male flowers beneath, each with a lobed calyx cup and three to five stamens with anthers covered in yellow pollen. The flower parts are clearly visible in this photo but even though it is heavily cropped they are still tiny. The entire catkin is only about 2 1/2 inches long.

The male flowers of gray birch (Betula populifolia) also appear in catkin form but instead of hanging down they often point straight up, as this one was doing.

The female flowers of gray birch turn into big, drooping clusters of seeds, which are also called catkins. You can see the size, habit and shape difference between the male and female catkins if you compare the large female catkins to the much smaller male one seen in the upper right corner of this photo.

Highbush blueberry (Vaccinium corymbosum) buds, like lilac and others, are imbricate buds with overlapping bud scales. It’s interesting that almost everything about the blueberry is red except for its berry. The new twigs are red, the bud scales are red, and the fall foliage is very red. Though small the buds are beautiful, and one of my favorites.

The chubby little green and purple buds of red elderberry (Sambucus racemosa) are also one of my favorites, but I don’t see them very often. Since they have more than two bud scales they are imbricate buds.

Some of the smallest buds I know belong to hawthorns (Crataegus) and the cherry red hawthorn bud in the above photo could easily hide behind a pea. There are over 220 species of hawthorn in North America, with at least one native to every state and Canadian province. In New Hampshire we have 17 species, so the chances of my identifying this example are slim to none. I know the tree in the photo well so I know that its blossoms will be white. Hawthorn berries are called haws and are said to have medicinal value. Native Americans mixed the dried haws and other fruits with dried venison and fat to make pemmican.  The dried flowers, leaves, and haws can be used to make a tea to soothe sore throats, and hawthorn also shows promise for treating heart disease.

Big, black and pointed mountain ash buds (Sorbus americana) often look like they have a single cap like bud scale but they actually have several overlapping scales which are quite sticky. You have to look closely at buds to see what is really going on, so it helps to have a loupe or a macro lens.

Norway maple (Acer platanoides) is supposed to be a very invasive species but they’ve been used for years as landscape trees so the genie has been let out of the bottle and now there is no stopping them. The Norway maple’s terminal bud and stem are larger than the sugar maple’s, and its bud scales are fewer and colored a pleasing maroon. Sugar maples have twice as many bud scales and they are brown. Norway maple terminal buds are also rounded while those of sugar maple are sharply pointed. Norway maple is native to eastern and central Europe and western Asia, from France east to Russia, north to southern Scandinavia and southeast to northern Iran.

Box elder (Acer negundo) is another member of the maple family and its buds and young twigs are often a beautiful blue or purple color due to their being pruinose. Pruinose means a surface is covered in white, powdery, waxy granules that reflect light in ways that often make the surface they are on appear blue. Certain grapes, plums, and blueberries are pruinose fruits. Certain lichens like the beautiful smoky eye boulder lichen have fruiting bodies (Apothecia) that are pruinose.

Terminal buds appear on the end or terminus of a branch and nothing illustrates that better than the sugar maple (Acer saccharum). The larger, pointed, very scaly bud is flanked by smaller lateral buds on either side. The lateral buds are usually smaller than the terminal bud. Sugar maple twigs and buds are brown rather than red like silver or red maples. I know that the sap is running so these buds will be swelling up and getting bigger before too long. In 2019 New Hampshire produced a below average 148,000 gallons of maple syrup but the season was 5 days shorter shorter due to cold weather. The average price per gallon in 2019 was $31.00. The record price per gallon was $40.70 in 2008.

Red maple flower buds (Acer rubrum) are small and round or oval with short stalks and 4 pairs of bud scales. The bud scales are often purple and / or tomato red and they have a fine fringe of pale hairs on their margins. They are one of the first to open in spring so I watch them closely beginning in March.

I realize that these bud posts probably don’t excite everyone like they do me but I hope people will look beyond all the imbricate, valvate and other fancy scientific labels and simply see the beauty. If the beauty that you see leads you to wonder and mystery, then you can start trying to find out more about what you’ve seen. Some think that beauty comes in the form of snow capped peaks or far off landscapes and indeed it does, but beauty also comes in the form of tiny tree buds. In fact beauty is all around you and the more you look for it the more of it you’ll see. Here’s hoping you’ll see plenty.

If you are open to being taught by nature, go listen to the trees. ~Kenneth Meadows

More Spring Blossoms

Dandelions have responded to a few warm days by blossoming heavily but many other plants don’t seem to be in any hurry and some are even blossoming later this year.

I’m always happy to see dandelions at any time of year. They are often one of our first flowers to bloom and sometimes one of the last as well.

Sometimes their flowers get frostbitten again and again but once the red maples (Acer rubrum) get started opening their buds keep blossoming no matter what the weather. This photo shows the male blossoms I found just opening on one tree. Each tiny red anther will become greenish yellow with pollen, which the wind will then carry to the female blossoms. They’re packed very tightly into each bud and there are thousands of flowers on a single branch.

This photo shows just how fast the blossoms can explode from the buds. I found the buds on the same tree as the ones in the previous photo fully open just a day later.

These are the female (pistillate) flowers of the red maple, just emerging. They are tiny little things; each bud is hardly bigger than a pea and each crimson stigma not much bigger in diameter than an uncooked piece of spaghetti. Once the female flowers have been dusted by wind carried pollen from the male flowers they will begin the process of becoming the beautiful red seeds (samaras) that this tree is so well known for. Many parts of the red maple are red, including the twigs, buds, flowers and seed pods.

I was surprised to find tiny little female American hazelnut flowers (Corylus americana) on a single bush recently. I think this is the earliest I’ve ever seen them. Reading back through spring blog posts shows that I usually find them in mid April, so why they’re blooming so early when many other spring plants are late, I don’t know. Native Americans used hazelnuts to flavor soups and also ground them into flour. In Scotland in 1995 a large shallow pit full of burned hazelnut shells was discovered. It was estimated to be 9,000 years old, so we’ve been eating these nuts for a very long time.

What is really baffling is why the female hazelnut blossoms have opened when the male catkins, shown in this photo, aren’t open. Without pollen from these male catkins the female blossoms are wasting their time. You can just see three tiny buds with female flowers above and to the left of these catkins. I think this is the first time I’ve been able to get both in a single photo. It gives you an idea of the huge difference in size.

Five days later the male catkins had opened but weren’t releasing pollen yet.

And five days later the female hazel blossoms were fully opened and looked as if the were reaching for that pollen. By the time the wind brings it to them they’ll be very sticky and receptive. If everything goes well I’ll be able to show you hazelnuts this fall.

Sugar maple buds are indeed swelling quickly and will probably be blossoming in a week or two. That will mean the end of the maple sugaring season this year. I saw a maple stump that had been left by a beaver the other day and it was bleeding sap heavily, so it’s running well right now.

Cornelian cherry buds (Cornus mas) are still opening, but very slowly. The yellow is the actual flower. They’re usually always in bloom by mid April and it’s looking like they will be this year as well.

I thought I had wasted my time when I didn’t see any flowers on the willows, but I heard red winged blackbirds in the alders and that was even better. Ice is melting quickly off the smaller ponds and vernal pools and soon we’ll hear the spring peepers.

It was a rainy day when I was taking photos for this post and all the crocuses were closed so I thought I’d show you this shot from last week, but then the sun came out and they all opened again.

I saw some new white ones that were pretty.

I thought that some of the white ones were even prettier when they were closed.

This blossom had just a naked stem and no leaves, so I’m not sure exactly what it is but I’m guessing it was a crocus but I can’t remember ever seeing pleats in the petals of a crocus.

The reticulated irises (Iris reticulata) have finally blossomed. They’re often the first spring bulb to flower here and I’m not sure what held them back this year. I’ve seen them bloom in the snow.

I thought this one was very beautiful. I’ve never grown them but from what I’ve seen these bulbs seem to slowly peter out and disappear. Groups of 10-15 flowers a few years ago now have only 1 or 2.

I wish you could smell these flowers. There is a spot I know of with about 8 large vernal witch hazel shrubs all in bloom at once and their fragrance is amazing. I can smell them long before I can see them. I can’t think of another flower that smells quite like their clean, slightly spicy scent.

There is a lot of promise for the future. Many of these hyacinth buds were showing color.

I didn’t see any color on the daffodil buds but they’ll be along. I expect by mid April spring will be in full swing with new flowers appearing every day. I hope everyone will be able to get out and enjoy it.

So many hues in nature and yet nothing remained the same, every day, every season a work of genius, a free gift from the Artist of artists. ~E.A. Bucchianeri

So Where is Spring?

Both the groundhog and the National Weather Service predicted an early spring, but how early? As I write this there are only 22 days until the calendar says spring, so I thought I’d go looking for it. It’s hard to describe how or when spring happens but sometimes it starts with a hint of warmth on a breeze. You can tell that it’s different than other breezes but you don’t know why; you just know that it’s that first warm breath of spring. But that’s just one sign. There are others, like the ice starting to melt off ponds. Even though we still have cold days the ice melts slowly, and it might freeze and refreeze but the sunshine and warmth will win out and before long there will be open water where the ice was. It’s happening now; that spot of open water in this photo has slowly been getting bigger.

More and more trees, and especially willows like the one seen here, are changing into their spring golden colors. It’s something I’ve watched happen for years now, one of those first subtle hints of spring. One lady said her ponies shedding their hair was a sign of spring for her, and skunks coming out of hibernation is another. Seed displays are also popping up in stores.

Willow catkins, called “pussies,” are a sign of spring for many but this year I saw them in January.

The purple bud scales on these red maple buds (Acer rubrum) have definitely been pulling back to reveal the tomato red buds within since the last time I looked at them. The bud scales protect the bud from freezing weather, so I hope the tree knows what it is doing. I’ve seen red maples bloom too early and lose most of their flowers to frost.

I get to see this sugar maple (Acer saccharum) every day so I’m sure the bud scales have been slowly opening on it as well. But, since I haven’t seen any sap buckets yet, buds getting bigger doesn’t make much sense because it’s the sap that drives the growth.  Maybe the sap is flowing in some trees and not others. That sounds like a plausible answer, anyhow.

When I was a boy I used to get highly excited when spring came because that meant I could ride my bike to school again, and when I did I made sure to ride through as many ice covered puddles as I could. That’s why, whenever I see that thin, white, crinkly ice on a puddle it makes me think of spring. This ice wasn’t quite what I mean but it was on a puddle and it had some fantastic, feathery patterns in it.

Mud is also part of spring in these parts; so much so that we even have a “mud season.” That’s when dirt roads turn to something similar to quicksand for a week or two as things start to thaw and the frost comes out of the ground.

For me checking lilac buds is a rite of spring. I’ve been doing it for as long as I can remember, always starting about now, looking at them twice or three times a week for signs of swelling. It’s always exciting to see the bud scales finally fully open to reveal the deep purple, grape like cluster of flower buds within.

Some plants seem like they would do anything to be the first to bloom in spring, and these cress seedlings (I think) are one of those. These seedlings grew next to a building foundation where it’s a little warmer and I wouldn’t be surprised to see them blooming next week. Each plant would fit in a thimble and a whole bouquet of the white, four petaled flowers could easily hide behind a pea.

I saw some tulips up and out of the ground, standing about 3 inches high. There are bulb beds up against a building foundation and this must be why they’re up so early.

I hope those are more leaves coming along and not flower buds.

Reticulated iris grow in the same bed as the tulips. These are very early flowering plants and you can often find the tiny iris blossoms covered by snow.

Daffodils are also still up and growing in a raised bed at the local college. Raised beds drain and thaw earlier than the ground does but anything green in them can still be harmed by the cold, and those daffodils often get frost bitten. When that happens the leaves turn to mush.

I was surprised to see this beech bud curling, because curling like this is often a sign of bud break and it’s far too early for that. The curl is caused by the sun warming the cells on one side of the bud and making them grow faster than the cells on the other side. This causes a tension in the bud which will eventually cause it to open. For beech this usually means mid-May.

Here is a photo of a beech bud breaking from May 19th of last year. There are several leaves in each bud, all edged in downy, silvery angel hair. This is one of the most beautiful sights in a New England forest in spring and I’m very much looking forward to seeing it again.

I checked the skunk cabbages again and still didn’t see any of the blotchy maroon and yellow flower spathes but it shouldn’t be much longer. Since I’ve been keeping track the earliest I’ve seen them was in 2014. They were just coming up on Feb 2 that year and it looks like they might be a month later this year.

The spring blooming vernal witch hazels (Hamamelis vernalis) have bloomed earlier as well, but they’re waiting this year. The weather has been very strange so I’m not surprised. I’m guessing that once we get a week of above freezing temperatures all the early blooming plants will bloom at once.

Though they’re early bloomers I didn’t think there would be any sign of movement in magnolia buds. I just wanted to see their furry bud scales.

45 years ago I was doing some work for a man who suddenly said “Look at the bluebird on the fence.” I got a look at a beautiful blue blur and until just the other day I hadn’t ever seen another eastern bluebird. On this day there were 3 or 4 of them in a birch tree and I saw the beautiful color as I drove by. I stopped, grabbed my camera, and they actually sat still for more than a second or two; just long enough to jump out of the car and get these photos.

The bluebirds were eating the fruit (hips) of the invasive multiflora rose (Rosa multiflora) and of course that just helps it spread. Blue birds, from what I’ve read, are migratory and usually return to New Hampshire to nest in March, so these birds are a true sign of spring even if they are a little early. Oddly enough that beautiful blue color doesn’t come from any blue pigment in their feathers because there isn’t any. Instead it comes from a thin layer of cells on each feather that absorbs all wavelengths of color except blue. Only the blue wavelength is reflected so when we see the beautiful blue of this bird we are actually seeing a reflection. But no matter where it comes from it certainly is a beautiful shade of blue, as this male shows.

Bluebirds are called “bluebirds of happiness” and seeing them again after so long certainly made me happy. They could have stayed a little longer but I’m very thankful that I got to see them, however brief that visit was.

But no blue, not even the brightest summer sky, seems as blue as the bluebirds of spring.

Things I’ve Seen

Some of the most beautiful things that happen in a northeastern forest are happening right now, and I hope everyone living in the area will have a chance to witness them. Bud break, when a plant’s bud scales open to reveal the new leaves within, can be a very beautiful thing, as we see here in the velvety pink buds of striped maple (Acer pensylvanicum.) The larger center bud’s scales have just opened and leaves will appear shortly. Bud break can go on for quite some time among various species; striped and sugar maples follow cherry, and birch and beech will follow them, and shagbark hickory will follow birch and beech. Oaks are usually one of the last to show leaves. That’s just a small sampling that doesn’t include shrubs like lilac and forest floor plants that also have buds breaking.

Even the lowly horsetails are breaking bud beautifully. The fertile spore bearing stem of a common horsetail (Equisetum arvense) ends in a light brown, cone shaped structure called a strobilus. Since it doesn’t photosynthesize at this point in its development the plant has no need for chlorophyll, so most of it is a pale, whitish color. When it’s ready to release its spores the cone opens to reveal tiny, mushroom shaped sporangiophores.

The whitish “ruffles” at the base of each brown sporangiophore are the spore producing sporangia. When the horsetail looks like the one in the photo it has released its spores and will soon die and be replaced by an infertile stem. Nature can seem very complicated at times but it always comes down to one simple thing: continuation of the species.

More people are probably familiar with the infertile stems of horsetail, shown here. They grow from the same roots as the fertile spore bearing shoots in the previous two photos and they do all the photosynthesizing.  Horsetails spread quickly and can be very aggressive. If they ever appear in your garden you should remove them as soon as possible, because large colonies are nearly impossible to eradicate.

Invasive Oriental bittersweet (Celastrus orbiculatus) is an expert at continuation of its species; not only does it produce berries that birds love; it also strangles the tree it uses to reach the most abundant sunshine. That can be seen here as this bittersweet vine slowly strangles an American elm. The vine is like a steel cable that wraps around the tree’s trunk and since the tree can’t break it, it often slowly strangles.

Cattails (Typha latifolia) have just started coming up. Cattails at the edge of pond can grow faster than fertilized corn in a field and can create monocultures by shading out other plants with their dense foliage and debris from old growth. They are also very beneficial to many animals and birds and even the ponds and lakes they grow in by filtering runoff water and helping reduce the amount of silt and nutrients that flow into them.  Cattails were an important food for Native Americans. Their roots contain more starch than potatoes and more protein than rice, and native peoples made flour from them.  They also ate the new shoots in spring, which must have been especially welcome after a long winter of eating dried foods.

A mallard swam serenely in the pond near the cattail shoots, so intent on something he saw on the far side that he didn’t even hear me walking on the trail.

Or so I thought anyway. He knew I was there but my presence didn’t seem to bother him and he just swam along beside me as I walked the trail. I think he was as curious of me as I was of him.

If you looked at the root of the aquatic arrowhead plant (Sagittaria latifolia) you’d see a whitish, chestnut size tuber with a shoot coming out of its top center. The shore of a local pond was littered with many shoots and since I know arrowheads grow here I’m guessing that’s what they were from. Though arrowhead plants are also called duck potatoes mallards eat only the seeds but muskrats, painted turtles and snapping turtles all eat the tubers. I’ve never seen a muskrat in this pond but I’ve seen many of both kinds of turtles here, so they may be the culprits.

All of the sudden I’m seeing turtles everywhere, as if someone flipped a switch. This painted turtle let me get one photo and then it was gone. Fossils show that painted turtle have been here for about 15 million years. They can be found from Canada to Mexico and Maine to California and can live for over 50 years. Native Americans listened for the turtle’s splash into the water and used it as an alarm and one native legend says that Painted Turtle put his paint on to entice a chief’s daughter into the water. I don’t know about that but they have certainly enticed many a child into the water, and I was one of them.

I doubt that painted turtles bother bullfrogs but I’d bet that snapping turtles do, and there are some big ones in this pond. I wondered if that was why this male bullfrog was sitting in the trail instead of in the water. He didn’t flinch when I walked to within a foot from him, and he let me take as many photos as I wanted. Bullfrogs are big; the biggest frog in North America, and the males do sound a bit like a bull. I’ve seen bullfrogs in the Ashuelot river that were so big they wouldn’t have fit in the palms of both hands held together.

He let me walk around him to take photos of his other side without moving. Since it was just the two of us it’s doubtful that he though I couldn’t see him. Male bullfrogs have very large tympanic membranes that cover their ears. They sit slightly below and behind their eyes and are always bigger than the eye. Females have tympanic membranes that are the same size as their eyes, even though female bullfrogs can be much bigger than males. In some Native American tribes frogs were considered medicine animals that had healing powers and brought rain. Some, like the Chippewa tribes, had frogs as their clan animal. Clan members take their clan animal as their emblem, but they don’t believe that their clan is descended from that animal.

This robin looked like it had been eating very well. I’ve never seen as many as we have lately; large flocks of them. In the past I’ve felt lucky to have seen a single bird in spring.

I love the movement in the young spring shoots of white baneberry (Actaea pachypoda) and I look for it every spring. This example had what looked like a prehistoric hand holding its flower buds while the newly opened leaves gazed down from above, enraptured. I fell under its spell for a while myself; it was such a beautiful and interesting little thing. This entire plant is poisonous and its berries especially so. They are white with a single black dot that gives them the common name doll’s eyes. In summer the berries follow a raceme of white flowers that is taller than it is wide, and which will grow from the tiny buds seen in this photo.

Japanese knotweed (Fallopia japonica) can be very beautiful as it spreads its new leaves to catch the sun. Unfortunately it’s also very invasive and almost impossible to control. I’ve seen Japanese knotweed shoots killed to the ground by cold in the past, and within 3 weeks they had come right back and grew on as if it had never happened. I’ve heard that the new shoots taste much like rhubarb but the plants grow into large, 4-5 foot tall shrub like masses that shade out natives.

Both cinnamon (Osmundastrum cinnamomeum) and interrupted ferns (Osmunda claytoniana) have fuzzy shoots, called fiddleheads because of their resemblance to the head of a violin. Ostrich fern (Matteuccia struthiopteris) must be up as well, and fiddleheads from that fern are considered a delicacy in many restaurants. Last year I went with a professional fiddlehead forager and saw thousands upon thousands of ostrich fern fiddleheads. Cinnamon and interrupted fern fiddleheads are very bitter and mildly toxic. In fact many are toxic and shouldn’t be eaten unless you know them well or are buying them at a store or restaurant. .

The male flower buds of American white ash (Fraxinus americana) appear before the leaves and can sometimes be colorful and sometimes black as blackberries. The Wabanaki Indian tribes made their baskets from ash. Some tribes believed ash was poisonous to rattlesnakes and used ash canes to chase them away.

The buds of sugar maple (Acer saccharum) have just broken on some trees and on others small leaves are already showing. The veins are prominent even on leaves that haven’t unfurled. Deer love to snack on sweet sugar maple buds and quite often you find only branch stubs and this time of year.

Red maple (Acer rubrum) leaves live up to their name when they’re this young. The red color in spring leaves is caused by the same pigments that bring the reds of autumn, the anthocyanins. That covers the how but little is really known about the why. One theory says that it’s because deer and moose can’t see red and therefore won’t eat the new, tender leaves. Another says that the red color protects the leaves from cold temperatures and damaging ultraviolet rays, but nobody seems to know for sure. I like to think the colors are there just to make the world a more beautiful place.

I meant to do my work today, but a brown bird sang in the apple tree, and a butterfly flitted across the field, and all the leaves were calling. ~Richard le Gallienn
