Posts Tagged ‘Red Maple Flower Buds’

I was hoping I’d be able to show flowers on the first day of spring and, though they might not seem like much, these vernal witch hazel petals (Hamamelis vernalis) just coming out of the fuzzy buds were wonderful to see. Actually tomorrow is the first full day of spring but it does start today.

Forsythia is a shrub that takes on a kind of golden hue in spring and this year many are going for broke.

Alder (Alnus) catkins are also coloring up, preparing to open and release the pollen from the male flowers, hundreds of which are hidden behind the scales of the catkins shown here.

Willow catkins aren’t showing any color yet but I think that any day now yellow flowers will start to show among the gray fuzziness of the catkins.

Crocuses are up and budded but I didn’t see any blossoms fully open yet.

It’s great to see a crocus, blossoming or not.

There are reticulated iris in the same bed as the crocuses and I think this might be one of them. they’re very early and often are the first spring bulb to bloom.

Daffodils are still thinking about things and can’t seem to make up their minds whether it is really spring or not. Who could blame them, with 60 degrees one day and 40 the next?

I remembered that what I thought were tulips a post or two ago are actually hyacinths. They look a lot alike at this stage and I seem to make the same mistake every year.

The daylilies at a friend’s house are up and about 3 inches tall, but they get warmth from the house’s foundation. They are an early plant but I haven’t seen any anywhere else yet.

I can’t explain the feeling I got when I saw the yellow buds showing on this Cornelian cherry (Cornus mas) but it was a good one. It wasn’t because the flowers are spectacular but more because it is a sure sign of spring and my heart soared at the thought of it. Many people haven’t heard of this non-native, early blooming shrub but it hails from the Mediterranean regions and was well known to Ancient Greeks and Romans. Archeological digs show that it’s small, tart, cherry red fruits have been eaten by man for thousands of years. It has quite small bright yellow, four petaled flowers that bees absolutely love.

I haven’t seen anything happening with the magnolias yet but soon their fuzzy caps will come off to reveal the buds within.

Lilac buds on the other hand, have started to open. You can see how the bud scales, which are very tight and shingle-like in winter, have started to pull away from each other. By mid-May they’ll be in full bloom and their wonderful fragrance will be on the breeze no matter where you go in this area.

Last year I saw red maple flowers (Acer rubrum) on March 25th. This means that these buds have about a week to fully open if they want to do that again and I think that they probably will because we’re supposed to have a week of above freezing temperatures.

But I’ve also seen red maple buds open too early, and the flowers have been badly frost bitten. Luckily the blossoming time of red maples is staggered from tree to tree and since not all flowers have opened there are always some that don’t get damaged by frost. In this shot the uppermost buds on the right and left look to be about ready to open.

I went to the forest where the spring beauties bloom. I didn’t expect to see any flowers but I wondered if I might see a leaf or two. I didn’t see any but they’ll be along soon. Many thousands of beautiful little spring beauties should carpet the floor of this piece of forest sometime in mid-April.

I didn’t see flowers but I saw that the beavers sure had been busy.

And so had the woodpeckers.

The mottled yellow and maroon spathes of skunk cabbages (Symplocarpus foetidus) are up and so thick you have to be careful not to step on them. If you do step on one you know it; the smell of skunk can be very strong sometimes. It’s too wet where they grow right now to kneel and get a shot of the flowers inside the spathe but I hope to be able to do so soon.

That’s a leaf shoot on the left of this skunk cabbage spathe, and that’s very unusual. The leaves don’t usually appear until after the plants have bloomed. Young leaves can resemble cabbage leaves, but only for a very short time.

Here’s another beautiful vernal witch hazel that I found blooming by following the scent. I know a place where several large shrubs grow. When I visited them I couldn’t see any blossoms but I could smell them so I knew they were there somewhere. And they were; way in the back was a single branch loaded with these blossoms. Their wonderful clean scent has been compared to a load of laundry just taken in from the line, and that’s as good a description as I’ve heard. Maybe a tiny bit spicy as well for this variety.

The first day of spring is one thing, and the first spring day is another. The difference between them is sometimes as great as a month. ~Henry Van Dyke

Thanks for coming by. Happy first day of spring!

This relatively warm weather and rain we’ve had for weeks now have left me with a longing for spring but it is only January, so about this time every year I scratch my itch for spring by looking at buds. Being able to identify trees and shrubs by their buds can come in handy, especially in winter, and it is a skill that any serious nature lover should have in their bag of tricks. It adds another dimension to nature study and makes it even more interesting. The bud shown above is from a speckled alder (Alnus incana,) and it has two bud scales. Bud scales protect the bud within and keep it from freezing. Buds with just two (sometimes three) scales are called valvate buds. The scales meet but usually do not overlap.

A catkin like this one on the same speckled alder is simply a long string of buds, in this case male buds, and each purple bit is a bud scale. I took this photo because it shows the gummy resin that fills the spaces between the scales of many buds. This makes the bud waterproof and this is important, because if water reaches the bud and freezes the bud will die.

This Cornelian cherry bud is another 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. 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. Just as the plant flowers the ground under it will be littered with these hairy caps for a short time.

I saw something on the magnolia that I’ve never seen before; seed pods. At first I thought it was some type of gall.

I’ve done bud posts before but this year I wanted to show some buds I hadn’t shown before. The alder is one and this sweetgum bud is another. If you know anything about sweetgum trees or how cold it can be here in New Hampshire you are probably wondering how I took a photo of a sweetgum bud without driving south. After all, the sweetgum (Liquidambar styraciflua) reaches the northernmost limits of its natural range along the coast just above of New York City, but these trees grow near a massive wall of brick and that keeps them warm enough to thrive here in the cold. 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.

The identification of the sweetgum trees came easily because of their strange seed pods. I’ve read that the infertile seeds found in each of these gummy pods are a source of shikimic acid, which is one of the main ingredients in Tamiflu, so if you had a flu shot and get through winter without getting the flu this year you can thank a sweetgum.

The leaves of the sweetgum seem almost evergreen but I’m really not sure if they are or not because they aren’t supposed to grow this far north. I wonder if the radiant heat from the mass of brick they grow near has them completely baffled. By the way, if you have green plants by the foundation of your house in January the same thing is happening, but it’s your furnace instead of the sun that supplies the radiant heat. It’s fairly common in cold climates.

The oddest thing about the sweetgum tree in my opinion is its strange flattened branches. The first description of the sweetgum tree came from Spanish conquistadors who wrote of its use by the Aztec chief Montezuma. He was using the tree’s resin to flavor a pipe full of tobacco, which was another plant the Spaniards had never heard of. It must work well because it is still used to flavor tobacco today.

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.

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.

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.

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.

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. Even squirrels don’t like these trees; last fall over several days I watched five or six squirrels cut all of the unripe seeds from a Norway maple. In just a few days the ground under the tree was littered with them and there wasn’t a seed left on the tree. 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.

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.

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. 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.

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.

For those who can’t see or don’t want to look at small buds 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 and 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.

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.

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

 1. Sap Buckets

People who collect maple sap the old way in buckets like these are becoming a rare breed. The sap is flowing but syrup producers say it’s coming slowly, in fits and starts, because we’ve had so many cold days. Daytime temperatures need to be in the mid-forties and nighttime temps at around 28 degrees  for optimal sap flow. Though some days and nights have been perfect it hasn’t been consistent. We’re still seeing below zero nights and, since the 4-6 week season ends in early April, each cold snap brings a renewed sense of urgency. Last year New Hampshire produced 176,000 gallons of syrup. In the abnormally warm winter of 2012 producers didn’t even see half that amount, and this year it might be cold that hinders production.

 2. Muddy Road

When we have the kind of cold we’ve had this year it drives the frost deep into the ground. In spring when the soil begins to thaw the water can’t seep into the frozen ground so it sits on top, saturating the soil to the point where it can’t hold any more water. When the soil in question happens to be a road, things can get very interesting. Here in New England we call it “mud season” and when I drove over the road in the above photo I knew it was upon us, because it felt like I was driving on gelatin. Our roads become quaking quagmires that have been known to swallow even 40 foot long school buses.  If you’d like to see some photos of mud season in all its muckiness, just click here.

 3. Peat Mosses

In the swamps, peat mosses aren’t wasting any time. They seem to green up almost immediately after the snow melts. I just read that scientists took a piece of moss from part of an Arctic ice core sample that was over 1000 years old. When they exposed it to light and warmth the ancient moss grew just fine. This moss that is now green once again was alive when Rome was in its infancy. This is why some people wonder if mosses and lichens ever really die.

 4. Skunk Cabbage 

Skunk cabbages (Symplocarpus foetidus) are growing fast in spite of the cold nights. Since they produce their own heat through a process called thermogenesis, they don’t care how cold it is. This photo shows skunk cabbage spathes partly out of the soil. Once they reach full size they will open so flies can visit the flower covered spadix within.

 5. Vernal Witch Hazel 

The vernal witch hazels (Hamamelis vernalis) keep poking out their strap like petals, only to roll them back up again because of the cold. They, like the maples, are going through fits and starts this year.

 6. Red Maple Buds

Red maple (Acer rubrum) and other tree buds are swelling and the hills off in the distance have taken on a reddish haze that is impossible for me to take a photo of, so I settled for a branch. Red maples are one of the first trees to flower in spring and I always look forward to seeing them because they are very pretty. The sap can be made into syrup just like that of sugar maples but it turns bitter when the buds start to break. Since they appear earlier than those of sugar maples, the season doesn’t last as long.

 7. Red Maple Buds

Both red and sugar maple buds are high energy foods and eastern gray squirrels eat them in spring. These buds also have high moisture content and that means that squirrels don’t have to leave a tree for a drink at this time of year.

 8. New Fern Growth 

I spotted this fern growing on a boulder. The cluster of round buds in its center will grow into new shoots, called fiddleheads, before too long. The only fern in this area with fiddleheads that are safe to eat is the ostrich fern (Matteuccia struthiopteris). They are considered an early spring delicacy but they need to be prepared and cooked correctly or they can make you sick. The Centers for Disease Control (CDC) has investigated a number of outbreaks of food-borne illness cause by raw and undercooked fiddleheads. They should always be boiled for at least 15 minutes.  Some say you can also eat lady fern (Athyrium filix-femina) and bracken fern (Pteridium aquilinum) fiddleheads but there is a great debate raging about the safety of eating them, so I can’t say for sure if you should or shouldn’t.

 9. Trailing Arbutus

The snow has melted enough to reveal the tough, leathery, evergreen leaves of trailing arbutus (Epigaea repens). My grandmother always called this plant mayflower but I’ve found its fragrant pinkish flowers much earlier in April. Because it has been so cold this year though, it might live up to its common name. I usually find it in mixed forests growing on sunny embankments.

 10. Oak Leaf on Snow

Last year’s oak and beech leaves are starting to fall. More signs of spring.

 11. Grasses in the Sun

The afternoon sun catching these dry grasses looked very spring like, but the scene looked better in person than it does in the photo.

12. Melting Snow

Sometimes spring comes creeping in quietly and slowly and is hardly noticeable, so we seem to go from winter right into summer. I have a feeling that this year will be that way.

Tomorrow, the first day of spring, will mark the 3 year anniversary of this blog. I remember wondering how I’d ever get through 6 months of it, so thanks go to all of you who have kept it going.

 1. Thawing Stream

This winter has been colder than we’ve seen in several years, but the coldest winters always seem to come with a short break called a January thaw, and we’ve had ours this year. I think of it as a taste of spring in the dead of winter, and it is always welcome. January thaws usually last for about a week and temperatures rise an average of 10° F higher than those of the previous week. Spring has always been my favorite season so for me a thaw is also a tease that lights the pilot light of spring fever. By the end of February the fever will be strong.

 2. Icy Trail

It’s hard to tell from the photo, but that’s ice on the trail. I was glad that I wore my Yak Trax because there was nowhere you could go to avoid it except back the way you came.

 3. Multicolor Gill Polypore Lenzites betulina

At first glance you might think these were turkey tail fungi (Trametes versicolor), but it’s important to look at the underside of mushrooms when trying to identify them. Though they aren’t always shown on this blog I always try to get photos of their spore producing surfaces and any other features that might help in identify them.

4. Multicolor Gill Polypore Lenzites betulina

The undersides of the mushrooms in the previous photo show that these fungi can’t be turkey tails because turkey tails have pores, not gills. Though many bracket fungi have gills, the multicolor gilled polypore (Lenzites betulina) shown in the photos is the only one that has both gills and white flesh.  All of the other gilled bracket fungi have reddish brown flesh, which makes identifying the multicolor gilled polypore much easier than most. I also carry a pen and a small notebook to note things like white or brown flesh but a lot of times I don’t use it because I don’t like harming the mushrooms. I like to leave the woods exactly as I found them if I can, so the next person can see the same things I’ve seen.

 5. Fern Growing in Boulder Crack-2

Evergreen intermediate wood fern (Dryopteris intermedia) looks fragile, but it can take a lot of weather. I found these examples growing in a crack in a room sized boulder. This is one of just a handful of true evergreen ferns. I usually expect to find another evergreen fern called polypody or rock cap ferns (Polypodium vulgare) growing on boulders but I didn’t see any in this area.

 6. Melt Runoff

The only time nature seems to be in a hurry is when snow melt rushes downhill. There was a lot of rushing going on this day.

 7. Melting Ice

All that water had to go somewhere and with the soil still frozen a lot of it puddled up in low spots in the woods. Mini ponds like the one in the photo could be seen everywhere.  Many were about the size of back yard skating rinks and once re-frozen they would have been great to skate on.

 8. Ashuelot Ice Shelves Collapsing

Along the Ashuelot River the ice shelves hanging out over the water were collapsing under their own weight. Not a good time to find yourself accidentally standing on one of these!

 9. Jelly Crep Mushrooms aka Crepidotus mollis

Jelly creps (Crepidotus mollis) are small, quarter sized “winter mushrooms” that like to grow on hardwood logs. They are also called soft slipper mushrooms and feel kind of spongy and flabby, much like your ear lobe.

 10. Jelly Crep Mushrooms aka Crepidotus mollis

The gills of the jelly crep are soft and turn from whitish yellow to brown as they age. You can see how these mushrooms grow in overlapping tiers in this photo.

11. Red Maple Buds

Red maple flower buds (Acer rubrum) are just waiting for the signal. These are one of my favorite early spring flowers and I’m looking forward to seeing them again. The flowers, twigs, leaf stems, seeds, and autumn foliage of this tree all come in varying shades of red.

The sun came out,
And the snowman cried.
His tears ran down
On every side.
His tears ran down
Till the spot was cleared.
He cried so hard
That he disappeared.

Here are some of the things I’ve seen in woods, parks and yards this week.

 1. Skunk Cabbage in Snow

The skunk cabbage flowers (Symplocarpus foetidus) just shrugged off the recent snow and melted their way through it. These plants use cellular respiration to produce energy in the form of heat, and can raise the air temperature around themselves enough to melt snow and ice. The process is called thermogenesis, and very few plants have this ability. In spite of being able to fuel their own furnaces, these plants don’t seem to be in any hurry to grow leaves. You can see a small one just starting between the two flowers.

 2. Amber Jelly Fungus aka Exidia recisa

Amber jelly fungus (Exidia recisa) looks like cranberry jelly to me, but the software I use to cheat color blindness sees more brown than anything else. This fungus likes to grow on willow trees and is also called willow brain fungus. It also grows on alders and poplars, and that is where I usually find it.

3. Red Maple Buds

The plum colored bud scales of red maples (Acer rubrum) have opened enough to let the tomato red flower buds begin warming in the sun. It won’t be too much longer before we see the bright red blossoms dangling from this tree’s branches.

4. American Elm Buds

The oval, flat, pointy buds of American elm (Ulmus americana) also have plum colored scales, but what they hide inside is much browner than that of red maple. Before Dutch elm disease wiped out most of our elms in the 50s and 60s Keene, New Hampshire had so many huge old elms that it was called the Elm City. Many businesses in the area still use Elm City in their names, even though most of the trees are now gone. There are a few hardy survivors widely scattered about the region though, and I visited one of them to get this picture. Elm flowers are beautiful enough to warrant a return trip.

5. Shagbark hickory Bud

The buds of shagbark hickory (Carya ovate) won’t win any beauty contests but they are slowly unfurling themselves, just as the earth is slowly warming and awakening to welcome spring.  There is no doubt that nature is turning to a new season, whether we are watching or not.

6. Scilla

Speaking of awakening-the scilla (scilla siberica) bulbs that I planted 2 years ago are just starting to show some color. It’ll be nice to see their cheery blue blossoms under the honeysuckles at the edge of the forest again. These bulbs are easily confused with glory of the snow (Chionodoxa) because the differences are so slight (flattened stamens) that even botanists have trouble telling them apart. It is for that reason that many botanists think the two plants should be classified as one.

 7. Cornelian Cherry Bud aka Cornus mas

We’re lucky to have a cornelian cherry (Cornus mas) in a local park and I was happy to see it showing some color. This very unusual, almost unknown shrub isn’t a cherry at all-it is a in the dogwood (Cornus) family and blooms very early in the spring before the leaves appear. It hails from Europe and Asia and has beautiful yellow, 4 petaled flowers that grow in large clusters. This is a rarely seen, under-used plant that would be welcome in any garden.

8. Box Flower Buds

Also getting ready to bloom was this boxwood shrub (Buxus sempervirens.)  Though the buds are white, soon small greenish yellow flowers will line each stem at the leaf axils. This shrub is very common and is often used for hedges.

9. Oak Rough Bullet Gall

Rough bullet galls on oaks are caused by the oak rough bullet gall wasp (Disholcaspis quercusmamma.) According to the Iowa State University Extension Service, in the fall the adult wasp chews its way out of the gall and lays its eggs in the dormant terminal buds of the oak host tree. In the spring when the egg hatches and the white, legless larvae feeds the oak tree will grow around it, completely enclosing it in a gall. The larva feeds on the inside of the gall, becomes an adult, and the cycle repeats itself. These galls are found only on bur oak, (Quercus macrocarpa,) and swamp white oak (Quercus bicolor.) The galls don’t hurt the tree, but they do excrete a sticky substance which attracts ants and bees.

 10. Opened Goldenrod Gall

 In this case the cycle didn’t get to repeat itself, because a bird pecked its way into this goldenrod gall and ate the fly larva it found inside. If the larva had escaped the gall on its own the evidence would be a tiny, round hole-not the large, ragged gash seen in the photo. Chickadees, woodpeckers, and even some beetles eat the larva of the goldenrod gall fly (Eurosta solidaginis.)

 11. Scattered Rock Posy Lichen

I went back to visit the one scattered rock posy lichen (Rhizoplaca subdiscrepans) that I know of in this area to see what affect the recent cold and snow had on it. It doesn’t seemed to have changed at all since I saw it last month, except maybe for a few more flat, pale orange fruiting bodies (Apothecia.) It grows on granite in full sun.

Only with a leaf
can I talk of the forest.
