Posts Tagged ‘Highbush Blueberry Buds’

On Easter Sunday I went for a walk along the Ashuelot River in Keene. This trail, possibly used by Native Americans for thousands of years, is one of my favorites. 12 Native American historical sites have been found along the Ashuelot River, including the oldest known evidence of humans in New Hampshire dating back 10,500 years.  I’ve walked here for over 50 years and think I know it well, but I see new things each time I visit.

This day’s new thing were these strange orange buds on the shrubs that the river had swamped.

At least I thought they were buds; they’re actually the male catkins of the sweet gale (Myrica gale.) Sweet gale  is also called bog rosemary. It likes to grow on the banks of acidic lakes, bogs and streams. Touching the foliage releases a sweet, pleasant scent from its resinous leaves which have been used for centuries as a natural insect repellent. Though it is a native plant here it also grows native in Europe, where it is used as an ingredient in beer making in some countries. It is also used in an ointment used to treat sensitive skin and acne. I was hoping to see some of the scarlet female flowers but I think I was too early.  

The banks of the Ashuelot are lined with highbush blueberries (Vaccinium corymbosum) and their buds had swollen to bursting, easy to see against the blue of the water. The highbush blueberry is a native plant that you can quite literally find just about anywhere in this part of the state.

The bud scales have opened and, though I didn’t see any leaves yet, I think it’s safe to say that bud break has happened among the blueberries.

Bud break is defined as “when the green tip of a leaf can be seen emerging from the bud,” and these new cherry leaves more than fit that description. You can see how the bud scales have curled and peeled back to release the new growth within.

The stamens of male box elder flowers (Acer negundo) hang down from the buds on long filaments and sway in the breeze. Box elder is in the maple family but its wood is soft when compared to other maples. Several Native American tribes made syrup from its sap and the earliest example of  a Native American flute, dating from 620-670 AD, was made from its wood, so it seems appropriate that the trees would grow here along the river.

I saw two turtles on a log but my camera doesn’t have enough reach for anything better than this. As soon as I hit the trail the sun went behind a cloud and stayed there the whole time, so the turtles were gone when I returned. Of course as soon as I left the trail the sun came back out.

The trail through these woods isn’t that far from where the railroad repair depot used to be in Keene, and the trail is black because it was “paved” with the unburned slag from the big steam locomotive fireboxes.

This slag is usually called “clinkers” or “clinker ash” and it is made up of pieces of fused ash and sulfur which often built-up over time in a hot coal fire. Firebox temperature reached 2000 to 2300 degrees F. in a steam locomotive but they still didn’t burn the coal completely. A long tool called a fire hook was used to pull the clinkers out of the firebox and in Keene we must have had tons of the stuff, because it was used as ballast on many local railroad beds. The section that ran by my house was as black as coal and I learned at a very young age not to walk barefoot on it. Those clinkers are sharp.

When a spring beech bud (Fagus grandifolia) grows longer and starts to curl like a rainbow it is getting ready to open. The buds I saw this day have a while to go but you can see the curl starting. The curling begins when the sun shining on one side of the bud causes the cells on that side of the bud to grow faster than those on the other, shaded side. This causes tension in the bud, making it curl first and eventually making it tear open its bud scales, releasing the new growth within. When beech buds break the new growth looks like downy, silvery angel wings for just a very short time. It’s one of the most beautiful things in the forest and well worth watching for.

The roots of this young beech caught my eye.

And the thorns of this multiflora rose caught my clothes. Invasive multiflora rose (Rosa multiflora) originally came from China to be used as an ornamental and as the old story goes, almost immediately escaped and started to spread rapidly. It grows over the tops of shrubs and smothers them by using all the available sunshine. I’ve even seen it reach thirty feet into trees. I wouldn’t be at all surprised if it was imported more for its scent than any other reason, because to smell it is like smelling a bit of heaven on earth.

The hips of a multiflora rose are about the size of a pea, so that should tell you something about the size of that spider.

The fuzzy white buds of shadbush (Amelanchier canadensis) were seen here and there along the banks of the river. Shadbushes originally got their name from the way they bloomed when the shad fish were running upriver to spawn, including here in the Ashuelot. Another name, Juneberry, refers to when its fruit ripens. The fruit is said to resemble a blueberry in taste, with a hint of almond from the seeds. Shadbush wood is brown, hard, close-grained, and heavy. It can also be very straight, and Native Americans used it for arrow shafts. Shadbush makes an excellent garden shrub or small tree and is easily found in nurseries. It grows naturally at the edge of forests and along waterways.

The bark peeled off an old dead birch and revealed a bright orange fungus.

I thought I’d found something on a tree that I had been looking for for a very long time; an asterisk lichen (Arthonia radiata.)

But it was a common script lichen (Graphis scripta.) it is also called the secret writing lichen, for obvious reasons. I’ve never been able to decipher their meaning but I enjoy seeing them.

One of the reasons I wanted to come out here was to see if the trout lilies that live here were blooming. They weren’t but the plants looked very robust and healthier than those I’ve seen in other places. I have a feeling this colony will be beautiful when they all are in bloom.

This trout lily leaf came up through one of last year’s leaves so it couldn’t unfurl. Which leaf will win, I wondered.

The trout lilies grow by the little red bridge, which is my turnaround spot.

In July you can step over what is little more than a trickle in this spot and I’ve always wondered why they even put a bridge here, but on this day it was like someone had made a wide path of black marble for it to cross. This stream and many others empty into the Asuelot River, and that might be why the name means “collection of many waters” in Native American language.

Well, I didn’t see many flowers but I did see a lot of other things that brought me closer to spring; especially the swelling buds of many trees. I hope all of you are able to get outside and find a bit of spring for yourself and I hope you’ll be able to be able to stay safe while doing so.

If you have a river, then you should share it with everyone. Chen Guangbiao

Last week we had enough warm days to melt just about all the snow and then we had a rainy day on top of it, so the Ashuelot river was filled nearly to bankful. The word “Ashuelot” is pronounced Ash-will-ot if you’re from this area or Ash-wee-lot if you’re from away. The word is a Native American one meaning “collection of many waters,” and that’s exactly what it is; in Keene and surrounding towns all the streams and tributaries empty into this river, so it can fill quite fast.

I was able to practice my wave catching skills at the river in Swanzey. Nothing teaches you that a river has a rhythm more than trying to catch a curling wave in the viewfinder of a camera. The trick is to match your rhythm to the river’s. Too fast or slow with the shutter release and you’ve missed it.  

Blueberry buds are swelling and the bud scales are starting to pull back a little but it will be a while before we see leaves on them. Blueberries are everywhere you look here and many birds and animals (and humans) rely on a good crop each year. Most years nobody is disappointed. Native Americans called blueberries “star berries” and used them medicinally, spiritually, and as food. One of their favorite uses for them was in a pudding made of dried blueberries and cornmeal.

This is the first time an annual chickweed has appeared on this blog in March but some varieties of the plant are said to be nearly evergreen in milder climates, and we’ve had a mild winter. I think this one is Common chickweed (Stellaria media,) a very pretty little thing to see in March. And it was little; this blossom could easily hide behind a pea. I’ve read that chickweed is edible and is said to be far more nutritious than cultivated lettuce.

Ground ivy (Glechoma hederacea) has suddenly appeared here and there but I’m not seeing a lot of blossoms just yet. Soon I’ll be seeing flowers by the hundreds in some places. It’s a pretty little thing which can also be invasive, but nobody really seems to care.

I thought I saw a lot of frog eggs in this small pond but I couldn’t get a good shot of them. I left the photo in anyway though, because I liked the colors and because I wanted to tell you that spring peepers, the tiny frog with a loud voice, have started to sing. I heard them just the other day and it was a very welcome song.

There is yellow hidden in the willow catkins and I’m guessing that I’ll see flowers this weekend.

There just happened to be a poplar tree beside the willow and it too displayed its fuzzy catkins.

Red maples (Acer rubrum) have responded to the warm temperatures in a big way and though last week I saw a blossom here and there, this week I’m seeing them everywhere. This photo is of the sticky, thread like female stigmas that catch the pollen from male trees. Soon they will become seeds; many millions of them.

Last week I saw no male red maple blossoms but this week I saw thousands, and many were already producing pollen. This usually happens in mid-April, so this year they’re about a month early.

Virtually every part of the beautiful red maple tree is red, including the male stamens.

Male and female red maple flowers often grow on the same tree but this is only the second time I’ve ever seen them grow out of the same bud cluster as these were doing. Just when you think you have nature all figured out it throws you a curve ball.

Last week I looked at this spot and didn’t see a single sign of reticulated iris (Iris reticulata) but this week there was a basket full of them. What a beautiful color. They are also called netted iris; the “reticulata” part of the scientific name  means “netted” or “reticulated,”  and refers to the netted pattern found on the bulbs.

Each petal wore a pretty little badge. If I understand what I’ve read correctly reticulated iris flowers are always purple, yellow and white, but the purple can be in many shades that vary considerably.

But here was a very pretty little reticulated iris that looked blue to me and in fact my color finding software sees several shades of blue. Apparently this plant didn’t read what I read about them always being shades of purple.

I saw a different vernal witch hazel (Hamamelis vernalis,) much wilder looking than most of the restrained blossoms I see in spring. Quite often plant breeders have to sacrifice something when they breed for larger or more colorful blossoms, and often what is sacrificed is scent. I think that was the case with this plant because its scent was very weak. Many vernal witch hazels have a scent strong enough to be detected from a block away.

Hundreds of crocuses bloomed in one of my favorite color combinations.

Oh to be a bee, just for a day.

The fuzzy bud scales of magnolias are opening, revealing the buds within. Though the flowers of this one are white its buds are yellow.

American hazelnut catkins (Corylus americana) have taken on their beautiful golden spring color but the tiny male flowers aren’t showing quite yet. The catkins have lengthened and have become soft and pliable in the breeze though, so It won’t be long.

Tiny little female American hazelnut flowers are all over the bushes now so it looks like we’ll have a good crop of hazelnuts again this year. Native Americans used these nuts 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.

Yes that’s a dandelion. A lowly, hated weed to some but in March, to me it is as beautiful as any other flower I’ve seen. I hope you can see the beauty in it too.

The spring came suddenly, bursting upon the world as a child bursts into a room, with a laugh and a shout and hands full of flowers. ~Henry Wadsworth Longfellow

We had a big storm here last Friday but we saw more rain than snow, and little wind. I’ve heard that upstate New York saw 2-3 feet of snow and in Pennsylvania semi-trucks were blown over by the wind, so we got off relatively easy. We did see flooding in places as this photo of a flooded forest shows, but not enough to cause any real damage. Things may change again today, because the weather people are saying we might see as much as 18 inches of snow from this afternoon through nightfall on Thursday.

The Ashuelot River spilled out into this pasture but this is expected in spring and there are no buildings within the flood zone.

I think it was just 2 weeks ago when I watched people skating on this pond. Now there is open water. I was hoping to see some ducks or spring peepers but I didn’t see either.

Though our days have been warm, mostly in the 50s F, our mornings are still cold enough for puddle ice. This ice is very thin and often white because of all the oxygen bubbles in it, and it tinkles when you break it. Nothing says spring to me quite like puddle ice, because when I was a boy I used to ride my bike through it in the spring as soon as the snow melted. You can see many things in this ice, but on this morning it was a simple starburst.

I noticed that the hairy bud scales on a Cornelian cherry (Cornus mas) had opened to reveal the bright yellow flower buds they’ve been protecting. Once pollinated in mid-April the flowers will become sour red fruits that have been eaten by man for about 7000 years. In northern Greece early Neolithic people left behind remains of meals that included Cornelian cherry fruit and Homer, Rumi, and Marcus Aurelius all probably tasted the fruit. I would if I could ever find one but apparently the birds snap them up quickly, because I’ve never seen one.

I’ve been staring at this photo of a crocus blossom trying to figure out exactly what is going on, because you shouldn’t be able to see the central anthers in a closed crocus blossom. I finally realized that it has been cut in half lengthwise, so you can indeed see inside the blossom to the reproductive parts. Why or how anyone would do this while the plant was actually in the ground growing and blossoming is a mystery to me, but it is an interesting look at something rarely seen.

Another plant I was hoping to get a look inside was a skunk cabbage (Symplocarpus foetidus) so I went to visit them in their swamp and saw that many of the mottled spathes had opened since I was last here. I could see the spadix covered with flowers in this one, but could I get a shot of it?

I was able to, barely. The spadix is a one inch diameter pink or yellow, stalked flower head from which the small flowers emerge. The flowers don’t have petals but do have four sepals. The male stamens grow up through the sepals and release their pollen before the female style and pistil grow out of the flower’s center to catch any pollen that insects bring in from other plants. The spadix carries most of the skunk like odor at this point and it is thought by some that it uses the odor to attract flies and other insects that might pollinate it. Sometimes the spadix is covered with pollen but this one hadn’t seen any yet so the male flowers must have just opened.

I saw some over-anxious daylilies. I hope they know what they’re doing. They could easily find themselves under a foot of snow tomorrow. March can be a fickle month with 50 degrees one day and snow the next and right now the forecast looks wild.

Ever so slowly the buds of red maple (Acer rubrum) are opening. The purple bud scales pull back to reveal the tomato red buds within. It probably won’t be long before they blossom, unless we get a cold snap with the coming storm.

The vernal witch hazels are blooming with great abandon now, even though this day was a cool one. We probably won’t see another display like this one until the forsythias bloom.

I couldn’t tell if this blueberry bud was opening or not but it showed me that spiders are active, even in winter.

It looked like this huge old mother white pine tree held her baby in her arms and it reminded me of the book The Hidden Life of Trees by Peter Wohlleben. I’m reading it now and it’s a book that I’d highly recommend to anyone who is interested in learning more about nature.

If a forest is a cathedral, then this is its stained glass.

I saw some beautifully colored turkey tail fungi (Trametes versicolor.) Someday I hope to find out what determines their color. They seem to all be different so I would think that the wood they grow on must play a part in their coloration, but I haven’t ever been able to find anything written on the subject.

I was walking the grounds of the local college looking for blooming flowers when I came upon this Boston ivy (Parthenocissus tricuspidata.) The vine has nothing to do with Boston and it isn’t a true ivy, but it is the reason colleges are called “Ivy League.” Boston ivy is actually in the grape family and originally came from China and Japan.

Boston ivy will climb just about anything by attaching itself with tiny circular pads that form at the ends of its tendrils. The vine secretes calcium carbonate and uses it to glue itself to whatever surface it grows on, in this case brick. The glue can support up to 260 times its own weight and if you’ve ever tried to pull Boston ivy off a building you know how sticky it is.

I’m not wild about stone walls that were built with mortar but sidewalk firedot lichens (Caloplaca feracissima) sure are. These bright orange lichens love the lime used in cement and can often be found growing on concrete sidewalks, and that’s where their common name comes from. When you find them growing on stone in the woods it’s a great sign that you’re in an area with a lot of limestone, and there’s a good chance that you’ll find other lime loving plants, like many of our native orchids.

Sidewalk firedot lichens appear very granular and often show fruiting bodies but this example was quite dry and I couldn’t see that it was producing spores anywhere.

A pile of fallen fern leaves reminded me of nautili swimming under the sea. It is interesting how nature uses the same shapes over and over, especially spirals. The spiral was considered sacred geometry by ancient civilizations and is still used today. Sacred geometry involves sacred universal patterns used in the design of everything in our reality. Spirals for instance, can be found in everything from the nautilus to the sunflower and from our own DNA to entire galaxies.

Despite the forecast, live like it’s spring. ~Lilly Pulitzer

I don’t know why I get an itch to start looking at buds at this time of year but I always have. Maybe it makes me think of spring. Buds do give clues that the ground has thawed by taking up water and swelling, and if you watch a bud every other day or so in spring you can see it happen. I usually watch lilac buds, but nothing says spring like the sugar maple buds (Acer saccharum) in the above photo. Sugar maples have large, pointed, very scaly terminal buds 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 and the buds have several scales. Buds with many scales that overlap like shingles are called imbricate buds. A gummy resin fills the spaces between the scales and makes the bud waterproof. This is especially important in cold climates because water freezing inside the bud scales would destroy the bud.

For those who can’t see or don’t want to look at small buds like those on sugar maples fortunately there are big buds on plants like rhododendron. It also has imbricate buds that are large enough to see without magnification. 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.

You can see the gummy resin that glues some bud scales together on this gray birch (Betula populifolia) bud. Ruffed grouse will eat both the buds and catkins and pine siskins and black-capped chickadees eat the seeds of gray birch. Yellow-bellied sapsuckers feed on the sap and I’ve seen beavers take an entire clump of gray birch overnight, so they must be really tasty. Deer also browse on the twigs in winter.

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. The closest I can come is Gray’s hawthorn (Crataegus flabellata.) 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.

If you can’t identify a hawthorn by its buds then its thorns will help. On this example they were about 2 inches long and just as sharp as they look. Native Americans made fences around their settlements with brambles and thorny branches like those from hawthorns. They also made very sharp awls and fish hooks from hawthorn thorns.

The lilac buds (Syringa vulgaris) in the above photo are another good example of imbricate buds. Lilac buds are very red and in spring once the plant begins taking up water again they can swell quickly enough to notice, if they’re regularly watched. I’ve watched lilac buds in spring since I was just a small boy and it has always been one of my favorite things to do in the spring. They aren’t swelling yet but it won’t be long before spring is here.

Highbush blueberry (Vaccinium corymbosum) buds are also imbricate buds, and also very red. 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.

A bud I most look forward to seeing open is the beech (Fagus grandifolia.) There are beautiful silvery downy edges on the new laves that only last for a day or two, so I watch beech trees closely starting in May. Botanically beech buds are described as “narrow conical, highly imbricate, and sharply pointed.” In May they are one of the most beautiful things in the forest.

Buds with just two (sometimes three) scales are called valvate. The scales meet but do not overlap. This Cornelian cherry bud is a great example of a valvate bud. In the spring when the plant begins to take up water through its roots the buds swell and the scales part to let the bud grow. Some bud scales are hairy and some are covered with sticky resin that further protects the bud. Cornelian cherry (Cornus mas) 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. It has a long history with mankind; its sour red fruit has been eaten for over 7000 years, and the Persians and ancient Romans knew it well.

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.

Sycamore bud scales (Platanus occidentalis) are also made of a single brown cap which will fall off to reveal the bud only when the weather warms. When buds are covered by a single bud scale they are encircled completely by a bud scale scar when the scale falls off.

The mountain ash bud (Sorbus americana) in this photo looks like it has a single cap like bud scale but it actually has several overlapping scales which are quite sticky. It looks like a squirrel might have been nibbling at this one.

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. They have a fine fringe of pale hairs on their margins. Red maples can be tapped and syrup made from their sap but the sap gatherers have to watch the trees carefully, because the sap can become bitter when the tree flowers. Seeing the hillsides awash in a red haze from hundreds of thousands of red maple flowers is a treat that I always look forward to. Unfortunately I’ve found that it’s almost impossible to capture that beauty with a camera.

Box elder buds (Acer negundo) 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 often pruinose.

Staghorn sumacs (Rhus typhina) have no bud scales at all, so their naked buds are hairy and the hairs protect the bud. Another name for staghorn sumac is velvet tree, and that’s exactly what its branches feel like. Native Americans made a drink from this tree’s berries that tasted just like lemonade, and grinding the berries produces a purple colored, lemon flavored spice.

Hobblebush (Viburnum lantanoides) is another native shrub with naked buds. This photo shows that the flower bud in the center and the surrounding leaf buds are clothed more in wool than hair, but there are no scales for protection. Still, they come through the coldest winters and still bloom beautifully each spring.

Sometimes there is no flower bud at the end of a hobblebush branch so the leaf buds are able to clasp tightly together, and they always remind me of praying hands. I’m not sure what caused the dark spots on these examples. It’s something I’ve never seen before.

The chubby little green and purple buds of red elderberry (Sambucus racemosa) are some of my favorites, but I don’t see them often. I find that being able to identify trees and shrubs when they don’t have leaves adds another layer to the enjoyment of nature study, and I hope readers will try to learn a few. If you are interested in studying tree and shrub buds, start with one in your own yard that you are sure of like a maple tree, and then branch out to those you don’t know well. The following information might be helpful:

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.
Caplike bud: A bud with a single scale that comes off in the spring.
Naked bud: A bud with no scales.

Winter is on my head, but eternal spring is in my heart. ~Victor Hugo

1. Shagbark Hickory Bud

Each year at around this time I get an urge to start looking at the buds of our trees and shrubs to see if there are any signs of swelling. I could look at a calendar to see when spring begins but I prefer watching the plants in the forest, because they’re rarely wrong. Since I read in a local paper that maple sap had started flowing because of a warm December I had to go see for myself. The terminal buds of shagbark hickory (Carya ovata) shown in the above photo are quite large and can fool you into thinking that they are swelling because of spring sap flow but no, they’re this way all winter.

2. Shagbark Hickory Bud Break

Why do I care about watching buds swell? Because beautiful things come from them, like the newly opened bud of the shagbark hickory in the above photo shows. This photo is from a previous blog post of nearly 2 years ago. Unfortunately I won’t get to see this in person again until about mid-May but since it’s one of the most beautiful sights in the spring woods, it’s worth waiting for.

3. Shagbark Hickory Bark

If you’re not sure if what you’re seeing is a shagbark hickory bud just look at the bark. It’s obvious where the name shagbark comes from.

4. Hawthorn Bud

Hickory buds are some of the largest buds I’ve seen but some of the smallest 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. The closest I can come is Gray’s hawthorn (Crataegus flabellata.) I know the tree in the photo well so I know that its blossoms will be white.

5. Hawthorn Thorn

If you can’t identify a hawthorn by its buds then its thorns will help. On this example they were about 2 inches long and just as sharp as they look.

6. Lilac Bud

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. Buds that have several scales are called imbricate with scales that overlap like shingles. A gummy resin fills the spaces between the scales and makes the bud waterproof. This is especially important in cold climates because water freezing inside the bud scales would destroy the bud. The lilac bud (Syringa vulgaris) in the above photo is a good example of an imbricate bud.

7. Blueberry Buds

Highbush blueberry (Vaccinium corymbosum) buds are also imbricate buds. 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.

8. Cornelian Cherry Bud

Buds with just two (sometimes three) scales are called valvate. The scales meet but do not overlap. This Cornelian cherry bud is a great example of a valvate bud. In the spring when the plant begins to take up water through its roots the buds swell and the scales part to let the bud grow. Some bud scales are hairy and some are covered with sticky resin that further protects the bud.

Cornelian cherry (Cornus mas) 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.

9. Nanny Berry Bud

Native nannyberry buds (Viburnum lentago) are also examples of valvate buds. These buds always remind me of great blue herons or cranes. I think I might have misidentified several nannyberry berries as shadbush berries earlier last fall, so I’m counting on the buds to tell me for sure what they are. If they look like the above example they are sure to be nannyberry. If it wasn’t so icy right now I’d go and find out.

10. Magnolia Bud

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.

11. Red Maple Buds

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. They have a fine fringe of pale hairs on their margins. Red maples can be tapped and syrup made from their sap but the sap gatherers have to watch the trees carefully, because the sap can become bitter when the tree flowers.  I didn’t see any sign of these buds swelling but I hope they will soon. Seeing the hillsides awash in a red haze from hundreds of thousands of red maple flowers is a treat that I always look forward to. Unfortunately I’ve found that it’s almost impossible to capture that beauty with a camera.

12. Box Elder Buds

Box elder buds (Acer negundo) 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 often pruinose.

13. Beech Bud

Another bud I’m looking forward to seeing open is the beech (Fagus grandifolia.) There are beautiful silvery downy edges on the new laves that only last for a day or two, so I watch beech trees closely starting in May. Botanically beech buds are described as “narrow conical, highly imbricate, and sharply pointed.”

14. Witch Hazel Buds

I went out to look at buds but never expected to see any of them actually opening on January 30th, so you could have knocked me over with a feather when I found this vernal witch hazel (Hamamelis) with its petals just peeking out of its flower buds. We’ve had above average temperatures every month since November and have been 6 degrees above normal for January, but I think this shrub might be jumping the gun just a bit. It lives in a local park and I don’t know its name, but it’s a real beauty when it’s all in bloom in the spring. Since it’s blooming now the question is will it still bloom in spring?

15. Daffodil Buds

As if the witch hazel blossoms weren’t enough there were daffodils out of the ground a short distance away, and I started feeling like I had fallen down the rabbit hole. Plants can and do get fooled but not often. Right now most of the signs are pointing to an early spring and even Punxsutawney Phil, the weather predicting groundhog in Punxsutawney Pennsylvania, says spring is right around the corner.

16. Winter Tree Finder

I hope this little foray into the world of buds has left you wanting to go out and start looking a little closer at the branches of trees and shrubs in your own neighborhood. I started looking at our local trees years ago; right after the little paperback booklet in the above photo was published in 1968. I carried it in my back pocket and started trying to identify common trees that I already knew something about, like apples and maples. The booklet is still being published today and costs little, especially if you find it in a used bookstore. It is also online in PDF format, and you can find it by clicking on the word HERE.

Winter is on my head, but eternal spring is in my heart. ~Victor Hugo
