Posts Tagged ‘Cornelian Cherry Buds’

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

I saw a dandelion in full bloom Saturday even though it was a chilly, blustery day. Call it a weed if you will but to me it was as beautiful as any orchid and I was very happy to see it. Oddly enough though I went looking for coltsfoot (Tussilago farfara,) which is a dandelion look alike that blooms in very early spring, I didn’t find a single one.

Actually I saw a dandelion and a half. I can’t explain the half.

I’ve been watching the American hazelnut catkins (Corylus americana) closely and have finally seen some signs of life in them. In winter they are short and stiff, but as they move into spring they lengthen and become more flexible and blow about in the wind. Since hazels are wind pollinated this is all part of The Plan.

Male hazelnut catkins (and most catkins) are really just a long flower head. The bud scales can be clearly seen in this photo as they spiral around the center stalk of the catkin. Under each bud scale is a male flower loaded with pollen ready to be released to the wind, but for the bud scales to open they have to make room by pulling apart, and this is how the catkins sometimes double in length. As they pull apart and open they also change color and become golden, and that’s because we see the golden pollen rather than the bud scales. The bud scales, I’ve noticed, have just began to pull apart and that’s my signal to begin looking for the tiny crimson, thread like female flowers. It won’t be long now.

This shot of a Cornelian cherry bud (Cornus mas) shows maybe an easier to understand example of how bud scales pull apart to reveal the flower buds they’ve been protecting all winter. The same thing happens on the hazel catkins, but in a slightly different way. Cornelian cherry is in the dogwood family. Its common name comes from its small tart, cherry red fruit which man has eaten for thousands of years, especially in Mediterranean regions. It is one of our earliest blooming shrubs, but the buds are opening slowly this year.

My biggest surprise on this day was finding ground ivy (Glechoma hederacea) in bloom because I’ve never seen them bloom so early; they usually bloom in May. This wasn’t just a one flower fluke; there were a few blossoms in a sunny spot on a lawn and they were another example of how topsy turvy this year has been. I’m not sure I’ve ever seen dandelions and ground ivy bloom before spring bulbs, but the bulbs seem to be very stubborn this year. Even the reticulated iris and snow drops which are often the first flowers seen, are barely out of the ground.

You might think that this little flower is calling to insects that aren’t there but I’ve seen a surprising number of them out and about, in spite of the cold.

The daffodils are coming up by the hundreds, but I haven’t seen a single blossom yet

These are the daffodils that I was sure would be blooming on this day but they decided against it, and that was probably a good thing because nights are still falling into the 20s.

This photo of a mallard in ice shows how cold it has been but the thin ice along the river banks didn’t seem to matter to the ducks; they just kept on feeding. I also saw a great blue heron but didn’t get a photo of it.

I was hoping to show you at least one photo of a robin but though I’ve searched for days I haven’t seen a single one, so these tracks will have to do. Were they made by a robin? I have no idea but I found them in a known robin hangout. One day several years ago I was admiring some red maple buds in this spot and a male robin flew right down beside me and began kicking and scratching up leaves while looking right into my eyes and giving me a severe stare the whole time. I’m not sure what it was all about but we parted on good terms, I think.

I admired these red maple buds (Acer rubrum) again just as I had on the day of the robin years ago. The female blossoms had opened and were showing their sticky scarlet stigmas. These tiny flowers look a lot like American hazelnut female flowers, but hazelnut blooms are much smaller. Before long the forests will be a sea of scarlet haze for just a short time, so I have to make plans to climb soon.

Red maple trees can be male or female, or sometimes have both sexes on one tree as this one did. On this day the male flowers had also appeared and were loaded with pollen, as can be seen in this photo. The male flower stamens are actually pinkish red but the abundance of pollen makes them appear yellow green. If the wind does its job before too long each female blossom will become the winged seed pod (samara) that I think we’re probably all familiar with.

Here’s a closer look at the male stamens there in the lower right center, just poking out of the bud scales and as yet pollen free.

I’m guessing that the return to winter in March has extended the maple sugaring season, but the red maples beginning to flower signal the end is near. When the trees begin to blossom the sap can get bitter, but red maples bloom before others. I’ll have to look at some sugar maple buds and see if they’re opening too.

The buds of another member of the maple family, box elder, haven’t seemed to respond to spring just yet. The buds didn’t seem to be doing much but that was okay because I like to look at them for their beautiful whitish blue color. The color is caused by tiny wax crystals, there to reflect and protect the new twigs from harsh sunlight until they toughen up. At that stage they will be reddish. The waxy, dusty coloration rubs right off like it does on grapes, plums, and other fruits. Box elder (Acer negundo) has a special place in my heart because it was the first tree I ever planted. I must have been about 8-10 years old when I pulled a three foot seedling up by the roots at my grandmother’s house and stuffed it into a hole at my father’s house. It grew like there was no tomorrow and shaded the front porch perfectly, which of course was what I had planned all along. Why I was thinking of such things at such a young age is beyond me but there you go; sometimes we just have this inborn itch.

I don’t have any real history with magnolias because nobody in my family ever grew one, but I’ve always loved them just the same, especially the fragrant ones. The bud scales on magnolias are made up of a single furry cap with a seam, and on this example the bud scale edges were beginning to curl. This is a sign that the flower bud inside is swelling and pushing the bud scale off, so it shouldn’t be too long before we see these beautiful flowers again. I hope they don’t blossom too early though; the flower petals often get frost burned and turn brown.

The story of the ugly duckling always comes to mind when I look at shagbark hickory buds (Carya ovata) at this time of year and that’s because most people would probably wonder why I would even bother to take the time to photograph something as plain as this. I do it because these buds have a beautiful secret and I want to be sure I know when it will be revealed so I don’t miss it.

The “it” that I don’t want to miss is the breaking of shagbark hickory buds, because for a short time in mid-May they are one of the most beautiful things to be seen in the forest. I sometimes have to remind myself to breathe when I stumble upon a tree full of them because it’s a sight so beautiful it can take your breath away. This is just one reason of many why spring is my favorite season; the anticipation that comes from knowing that I’m living so close to seeing something so beautiful. “Any day now,” I tell myself as the excitement builds.

If a tiny bud dares unfold to a wakening new world, if a narrow blade of grass dares to poke its head up from an unlit earth, then surely I can rise and stretch my winter weary bones, surely I can set my face to the spring sun. Surely, I too can be reborn. ~Toni Sorenson

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’m sure everyone has heard about the great nor’easter of 2017 that hit us last week. This photo was taken in my back yard after I got home from work. It was snowing heavily.

Getting home was difficult and took me twice as long as usual. We didn’t have true blizzard conditions here but I hope I never have to drive through a storm like that one again because the wind was blowing the snow around so much it was hard to see where I was going. Some parts of the state were hit very hard and lost power for nearly a week. This photo could have been taken in January but unfortunately it was taken on March 15th. I took one in January at this same spot that looked almost identical.

At my house I had just over 10 inches of snow when I got home, and another 2 or 3 fell that night. Some places had twice what I had here.

After a week of temperatures in the high 60s F. and bare ground during the last week of February this storm and the bitter cold afterwards were disappointing. It was almost as if winter had been rewound somehow and was starting all over again, but the sun came back out as it always does and it’s getting gradually warmer, in fits and starts. Temps are back in the high 40s and the snow is melting again.

This shot of Half Moon Pond was taken before the storm. It was frozen over at this point but the ice was melting quickly and by the time the storm hit open water could be seen. Once the storm came it froze over quickly, and so it’s now covered in snow again.

If there is one thing I’ll remember most about this winter it is the ice. It has been terrible and is everywhere, including on all of the trails that I visit. Getting around has been difficult, to say the least.

Because of all the ice we’ve had to use many thousands of tons of salt and sand on the roads and walkways. This photo shows what our roads and walks look like now; stained by salt.

Spring is still on the march but you have to look for it because many of the signs are subtle, like when last year’s beech and oak leaves finally start to fall.

Also subtle is the swelling of buds; these lilac buds are a perfect illustration of how it happens. The dark red colors on the bud scales once met, so when you saw the buds they looked completely red. But then they began swelling and the red parts pulled apart, revealing an orange stripe. When you see this you know the buds are getting bigger. Before long the scales will pull back completely, revealing the tiny flower bud cluster inside. It’s a great thing to watch happen.

A single pea size bud of a Cornelian cherry (Cornus mas) illustrates how, when water taken up by the roots swells the bud, the bud scales open to reveal the flowers inside. This doesn’t happen on all plants; magnolias for instance have only a single furry bud scale that simply falls off.

In northern Greece early Neolithic people left behind remains of meals that included cornelian cherry fruit. Man has had a relationship with this now little known shrub for about 7000 years. The Persians and early Romans knew it well and Homer, Rumi, and Marcus Aurelius all probably tasted the sour red, olive like fruit, which is high in vitamin C. Cornelian cherry is in the dogwood family and is our earliest blooming member of that family, often blooming at just about the same time as forsythias do.

I was worried that the red maples (Acer rubrum) had misjudged the weather when I saw some flowers dangling on a few trees. Chances are good that the blossoms that appeared early are dead but as this photo shows, there are still plenty tucked into their bud scales.

These daffodils weren’t so lucky and these leaves are finished. They’ll probably still bloom but without leaves they can’t photosynthesize to make food, so they probably won’t bloom next year.

Some daffodils still looked good and I think what made the difference was the snow depth. Snow is a good insulator so it probably protected these budded plants from the cold, while the ones in the previous photo probably had no protection.

Once again I was amazed to see this vernal witch hazel (Hamamelis vernalis) blooming after a foot of snow and temperatures barely above zero. It’s a very tough plant and one I’d like to have.

A chipmunk peeked out of his tree to see if it was spring yet. I knew just how he felt, so for an instant we probably both thought as one.

One day you stepped in snow, the next in mud, water soaked in your boots and froze them at night, it was the next worst thing to pure blizzardry, it was weather that wouldn’t let you settle. ~E.L. Doctorow

Monday the first day of spring  marked the start of my seventh year of blogging, so a big thank you to all the regular readers for putting up with it for so long. I hope I’ll be able to show you many new things this year.

Thanks for coming by.

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.
