Drupes – Tendrils

Still There For The Birds

February 10, 2025

Fruits, berries, or technically drupes of Blackhaw Viburnum (Viburnum prunifolium). Waiting for birds to find them. As is the case here, sometimes it is well into winter before these drupes are discovered and eaten. A time when there are fewer things to eat. Located out by the end of my lane, I keep an eye on them, since I’m curious about when they will be eaten.

The Blackhaw Viburnum is a large bush or small tree, sometimes reaching a height of ten or twenty feet. Its flowers grow in a flat topped cluster, blooming in early spring.

Maple-leaf Viburnum

Just now beginning to leaf out, greeting spring. Maple-leaf Viburnum (Viburnum acerifolium), native to eastern North America, an understory, deciduous shrub.

It’s plentiful up here on my mountain, and is easy to identify with its twin, maple-like leaves. I’ve been fortunate to have received several of these shrubs as gifts. Shrubs that I’m watching grow as each year passes. Shrubs that add to my pleasure living in the woods.

The Maple-leaf Viburnum will mature to a height of six feet and a width of 4 feet. In early May pale pink buds emerge making way for soft white flat-topped flower clusters, know as cymes.

Maple-leaf Viburnum has a nectar that with its fragrance attracts bees, flower flies, moths and butterflies to help pollinate the flowers. It’s also a larval host of the Spring Azure.

The cyme, is one to three inches wide consisting of quarter inch wide individual flowers, a soft white often with a slight hint of pink.

These flowers must be cross-pollinated with another Maple-leaf Viburnum plant that is not an exact clone in order for berry-like drupes to appear in the autumn.

The fruits are attractive to many birds, including Ruffed Grouse, Cedar Waxwings, Cardinals, Hermit Thrushes, Eastern Bluebirds, Robin and Wild Turkeys.

If proper pollination takes place, the flowers give way to blue-black drupes in late autumn that may persist into the winter. The autumn leaf color ranges from shades of pink to red, leaning toward purple, and warm yellow. Gorgeous!

Gray Dogwood in Autumn

Gray Dogwood (Cornus racemosa). Gray Dogwood drupes providing sustenance to many birds and mammals as autumn thinks of becoming winter, leaving what resembles tiny red trees for snow to fall upon.

Its leaves provide a unique color palette of plum red and yellow chartreuse in an opposite arrangement as they succumb to diminishing daylight and cooler temperatures. Autumn at its finest.

White and Red Dogwood Berries

Autumn is approaching. The leaves of some Flowering Dogwoods are getting richer, more and more red. Their crimson berries, or drupes, are in abundance. This is the species of Dogwood that most people think of when “Dogwood” is mentioned.

Flowering Dogwood (Cornus florida) and Gray Dogwood (Cornus racemosa). Two different Dogwood species. One of seventeen species native to North America. Like most Dogwood species, these two have opposite leaves as well as leaves with visible veins that curve parallel to the smooth edges.

Gray Dogwood’s creamy white berries are plentiful now too, much to the pleasure of Cardinals, Flickers, Downy Woodpeckers, Bluebirds and many other songbirds.

Flowering Dogwoods grow as single trees. Gray Dogwoods form colonies, by growing suckers and spreading. These dense colonies create a perfect space for nesting songbirds. Glad to see these berries. Autumn is approaching!

Blackhaw Viburnum

A large bush that I’ve been delighted to find is Blackhaw Viburnum (Viburnum prunifolium). It’s growing by my backdoor, and there’s lots of it growing in the woods all around my cabin.

The leaves of Blackhaw emerge from the buds involute, or curled as a spiral. The mature, glossy, opposite leaves are three to four inches long and one inch wide with fine serrations and pointed at the end. The petioles, or stems, of the leaves are a reddish color. In the autumn the leaves turn a purply-red.

Soon my bush will have buds. Buds that will become clusters of fragrant flowers four to five inches across. Flowers that will attract bees and flies to do their pollination magic.

Blackhaw Viburnum is the host plant of Spring and Summer Azure butterflies. The later caterpillar instars of the Baltimore Checkerspot butterfly occasionally feed on its leaves. Oh I wish I’d see a Baltimore Checkerspot butterfly! I’ve seen their caterpillars while pulling invasives in Shenandoah National Park. Never the adult though.

Its fruits, called drupes, are about one half inch long. They’re eaten by songbirds, gamebirds, squirrels and chipmunks.

As a tree Blackhaw Viburnum can grow to be thirty feet tall. Its bark blocky in a Persimmon tree sort of way. Large bush, small tree, all in all a mighty cool plant.

Gray Dogwood

Just like the Flowering Dogwood (Cornus florida) that we see most often, Gray Dogwood (Cornus racemosa) has opposite leaves and those leaves look quite similar to Flowering Dogwood.

The flowers of Gray Dogwood arrive on dome shaped panicles, or branched clusters, in late May and June here in the Blue Ridge Mountains of Virginia.

The individual flowers in the panicles are one quarter inch across. Those flowers contain a short calyx with four small teeth, four creamy white petals, four stamens with soft yellow anthers, and a central pistil.

The branches of each panicle are creamy white like the petals, when the flowers are produced. In a short time they become bright red as the drupes, or fruit, matures. Anyone else see these as little teeny trees?

Nearly one hundred species of birds are attracted to these drupes from late summer into early autumn.

And as autumn descends upon these small trees the leaves turn a soft yellow with highlights of purply-red.

My favorite part of the year as Gray Dogwoods go through each of the seasons is of course, winter. Those teeny trees, which are actually the panicles that were in turn, for flowers and then, for drupes become the perfect receptacles for ice and iced spider webs as well.

Sassafras Trees Are Dioecious

Seems winter has given up. Spring has won the battle of the seasons and is stepping through the woods. Right now, mid-April, Sassafras Trees (Sassafras albidum) are in bloom throughout the woods of the Blue Ridge Mountains in central Virginia. Creating a soft watercolor wash of pale yellow.

Sassafras is a dioecious tree, meaning any Sassafras tree that you may come upon in the woods or in your yard is either a female tree or a male tree. Each individual tree’s flowers in turn are either female flowers or male flowers. The blossoms in the image immediately above are female flowers. Each female flower is very small at about one third inch across. Each has six sepals, an elongated central pistil and six small sterile stamens.

The male flower to my eyes looks like a busier flower. These are male flowers in the photo above. Each little flower, one third inch across, consists of six sepals and nine stamens with yellow anthers.

Going from tree to tree, the flowers are pollinated by various bees, flies, sawflies, beetles and wasps. Fertilized female flowers produce oval drupes. A drupe is also known as a fleshy fruit with thin skin and a central stone containing the seed. Drupe is easier to say.

When the drupes are ripe, reaching a deep blue-black color, seated on a pedicel that appears to be a rich red goblet, songbirds, Wild Turkeys, and Bobwhites enjoy the buffet and spread seeds through the woods. Bringing us more gorgeous Sassafras Trees.

Common Hackberry

Tree bark offers great opportunity to identify a tree during the winter. Some more straightforward than others. One tree that through its bark is a cinch to figure out, Common Hackberry (Celtis occidentalis). Its bark makes me think of a 3D topo map with all the ridges and valleys laid out and wrapped around the trunk.

The amount of furrowing increases as the tree ages. This image above is a younger tree than in the first photo.

Another point I pick up on in identifying, no matter what the season is, is the presence of Hackberry Galls, which are very often present on the twigs or leaves. These are caused by irritation of cells due to an insect called a Psyllid feeding on the Hackberry leaves and small branches.

In early summer you will find drupes (the fruit of the Common Hackberry Tree) on the trees. As the drupes mature they will go from green to a rich coppery purple color.

One last morsel of information not related to the identification of this tree is about a butterfly. The Hackberry Emperor (Asterocampa celtis) depends on the Common Hackberry Tree as its exclusive caterpillar host plant. No Common Hackberry Trees, no Hackberry Emperors.

Poison Ivy

Poison Ivy, Toxicodendron radicans

I’m feeling itchy already just anticipating writing this blog. It was not until I was well into my adult life that I first got a Poison Ivy rash, complete with huge blisters. OH! How very painful it was. Fast forward 30 years or so and I’ve grown to love, or at least truly appreciate the native plant.

Yes I do hold the plant in high regard, even though I am now extremely sensitive to urushiol, an oil found in all parts of the plant. The urushiol is not a defensive mechanism but rather aids the plant with retention of water. Urushiol is also found in Poison Oak, and Poison Sumac. A similar oil is found in the skin of Mangoes, and its leaves and bark. Nice to know about this. I won’t be chopping any Mango anytime soon, and will leave the preparation to someone else if it is on the menu. Eating the flesh of the Mango is no problem for me. The shell of the Cashew nut also contains a similar oil, and only creates a skin reaction until the Cashew is roasted. After roasting, the Cashew shell is problem free for those sensitive to urushiol.

This (photo above) is how a Poison Ivy plant starts out in spring, a brilliant crimson announcing its entry into the world. Perhaps the color is a warning. It certainly tips me off.

As spring begins to think of summer and warmth, as the Poison Ivy bursts forth with a thick growth of leaves, the plant blooms, with tiny pale yellow-green petals in clusters. The stamens are a standout color of school bus yellow.

As I’ve hiked my mountain trails I’ve noticed that one butterfly in particular will seek refuge on the leaves of the Poison Ivy plant. Time after time, individual after individual, Northern Pearly Eye butterflies (picture above) will alight on those leaves as if they provide some safety zone. These butterflies can feel safe. I will not hunt them down, except with my camera, while they are sitting on the Poison Ivy leaves!

Those leaves that are safety zones for some butterflies, can compete with any of the trees of autumn with their outstanding colors. Turning bright sunshine yellow, pumpkin orange or a rich deep red, they bring on an artist’s palette of warmth.

I am a big fan of Mother Nature whether it is birds, trees, flowers, frogs, toads, snakes, spiders, geology, weather – all aspects of it. This brings me to the above picture. The fruit of the Poison Ivy plant, drupes. Birds depend on these drupes as midwinter leaves them with few things to eat. I have seen many woodpeckers congregating on the Poison Ivy vines that wrap, cling and climb my huge oak trees in front of my cabin in late January. Little to eat but salvation in the Poison Ivy drupes.

The woodpeckers are not the only critters that find a meal at the Poison Ivy vine. Here a Chickadee dines on the drupes, keeping an eye on me, as he does.

I remove Poison Ivy when it emerges in one of my gardens, or on my paths that I regularly use, but if it is growing where only birds and the creatures of the woods venture, I leave it for them. I appreciate the beauty and the need for this native plant.

Sassafras

You know the question, If you were a tree, what tree would you be? My quick answer would be, a sassafras tree. I’ve had a cabin in the Blue Ridge Mountains, in Virginia, since 1992. During that time I’ve hiked my mountain up and down, getting to know all the things that grow here. I love them all, but the sassafras speaks to me. Speaks to me more than any other tree.

I’ll introduce you to the sassafras trees that I know here on the mountain. I’ll start with this season. Autumn. I am a color person. Color is extremely important to me. The sassafras celebrates autumn with splendid colors. Its rich green leaves, fading into lime green, butter yellow, school bus yellow, as the chlorophyll in its leaves fades away.

But that is just the beginning. The sassafras becomes a multicolored fiesta in autumn. Rust red, burgundy and many a shade of orange appear.

These leaves, like the twigs, bark and roots, all have the fragrance of root beer. Perfect timing: as I write this, my husband brings me an icy mug of root beer. Mmm! It takes me back to my childhood.

As I reminisce, I recall that sassafras oil has been determined to contain a carcinogenic substance, safrole. Root beer no longer contains safrole. You would be wise not to dig the roots of sassafras, to use as a root beer flavoring, or to make tea, as I did as a child. That lovely aroma, sure brings the memories back. But let’s be safe.

As the leaves fall, the intricate texture of the bark becomes my focus. And the color of the bark, just below the surface. A rich, cinnamon red-brown. Looking, just the right color, to match that childhood memories aroma. The bark, a lovely lacework of ridges, undulating this way and that.

And, like the bark, the trunks of the sassafras trees appear to dance through the forest. Like the bark pattern, bending this way and that. Winter is a favorite season for me. It reveals the trees’ structure. The trees’ form. Sassafras trees bend and sway, even in standing still.

Time flies and the sassafras trees’ buds are waiting for the first of the slightly warm days. At the beginning of April, they begin swelling and by the third week of April, here on Snow Mountain, the woods are filled with flowers.

Not much for show, but still beautiful to me. There is a soft, butter yellow haze in the woods. The flowers arrive before the leaves.

Now I am going to tell you a secret. As fond of sassafras, as I am, I had never seen sassafras drupes (one seeded fruit), until this summer. On finding some, I was amazed at their unusual look. Patriotic red and blue.

And yet, I understood why I had not seen them before. The leaves provide a perfect hiding place for the drupes. So much so, that it was a challenge to get a photograph to show you.

The drupes are popular with many birds and once they are gone, their receptacles are still attractive. Crimson against the green leaves.

Lovely sassafras has a weakness, if you are going to plant a few in your garden. If you are in an area prone to problems with Japanese Beetles, beware. Japanese Beetles really enjoy Sassafras leaves. Fortunately for me, my woods are my gardens. They are filled with Sassafras. A Japanese Beetle chomped away on this leaf, but there are still many, many more untouched.

But with that attractiveness to Japanese Beetles, it certainly has its strengths as well. Another critter that eats the sassafras leaf, is the caterpillar of Eastern Tiger Swallowtail. I consider that a big plus. Along with its beauty, it tolerates clay soils, and drought. Deer, and gypsy moth caterpillars will go for other things to eat, before they chomp on sassafras.

Once I became acquainted with the trees on the mountain, I realized that sassafras trees can grow to be quite large. Up to about 60 feet in height. They are most often seen as the understory shrub though.

Allelopathic is a term used to describe a characteristic of sassafras. That means the tree releases a chemical that hinders the health of some plants living around the sassafras. American elm is one of the trees that is affected by this chemical. This is a defense for the sassafras, eliminating some of its competition.

I am very fortunate being here in the woods. Sassafras trees come up as volunteers all over. I love it!
