Squirrel Corn

Dicentra canadensis

Note the finely dissected leaves of this early spring ephemeral–so pretty, dainty, and fern-like! The leaves actually look very similar to Dutchman’s Breeches! But this is Squirrel Corn, so named because the bulbs of the plants look like little corn kernels. (See the illustration in the gallery below.)

Like Dutchman’s Breeches, Squirrel Corn has small white flowers that dangle from a raceme above the leaves. But instead of dangling “pantaloons”, these flowers are distinctly heart-shaped and more-closely resemble Bleeding Hearts.

Look for this plant in hardwood forests on rich soils with rocky outcrops. I found these plants growing along Rock Castle Creek Gorge in April.  They were not in bloom when I saw them, hence the “borrowed photo” above from Wikipedia.

Mountain Lettuce

Saxifraga micranthidifolia or Micranthes micranthidifolia

Last weekend, on Easter Sunday, we stopped in for a walk at Rock Castle Gorge near the Blue Ridge Parkway. Loads of wildflowers were in bloom, but I did find a new one (new for me at least) that caught my eye as we ascended the gorge trail. I knew it was a saxifrage of some kind, but it was bigger than others I’ve seen before. Each time I saw it, it was growing close to, if not actually in the stream bed.

Bright green, with succulent leaves, I wasn’t totally surprised to later learn that it is called “Mountain Lettuce” or “Brook Lettuce”. Both describe the plant and its habitat well.

The very handy book “Wildflowers of Tennessee and the Southern Appalachians” describes Brook Lettuce as perennial, with basal leaves up to 8 inches long, oblong, sharply toothed, tapering to a winged petiole. The tiny flowers about one-quarter inch wide, with 5 white petals, each with a pair of yellow marks at the base. The inflorescence is branched, forming a large open panicle. Mountain Lettuce habitat is wet cliffs and mountain brooks; bloom time is April-June.

As for the “lettuce” part of the common name, apparently this plant was eaten as a salad green in times gone by and is still gathered by foragers now. It can grow up to three feet in height, making for quite a salad! 🙂

Check out the photos!

Spring 2017 is here!

In the interest of getting things started again here at Virginia Wildflowers, I am copying some photos from last spring to re-familiarize you with the progression of spring flowers that may be blooming in your area now. I’ve been out wandering these last few weeks, keeping a close watch on the ground for the “first signs of spring”, and now- after a slow start, there is plenty to report. In fact, spring 2017 is moving quickly due to the unseasonably warm temperatures. Here’s what’s happening in my neck of the woods (Southwest Virginia, elevation 2,000 feet, April 3rd):

Skunk Cabbage is past flowering and partially leafed out in all the soggy places nearby! Trout Lilies bloomed two weeks ago! Hepatica and Bloodroot flowers have already gone to seed, but if you get out there this week you may be able to still find a few!  Twin LeafDutchman’s BreechesColtsfoot, and Rue Anemone are in full flower now.  Golden Ragwort is unfurling masses of sunny blooms too. So much excitement, so little time!

The leaves of Wild Ginger are just coming up now, and the tall Virginia Bluebells are beginning to bloom (love them!). The woods around my house are literally carpeted with tiny, white and pink Spring Beauties.  Heartleaf, Trillium and Solomon’s Seal are poking their heads out of the ground too…they are still a little apprehensive about making an appearance.

On local list serves, I’ve seen reference to the fact that Morels are even up in some places in our area. I haven’t seen any myself yet, but that doesn’t mean a dedicated hunter couldn’t find some right now if they tried.  Recent rains should definitely help things along.

Be well, and happy trails this year!

Welcome to Virginia Wildflowers!

Virginia Wildflowers is a natural history photo gallery and casual field guide to wildflowers and mushrooms. I live in Southwest Virginia, so most of my photos were taken in this part of the state.

I’ve been taking photos of local wildflowers for five years now. I try to capture close-ups of leaves, stems and flowers with my digital camera, and then I post the photos along with basic natural history information. In the spring and summer of 2015, I reordered the species by season (at least roughly), so hopefully they will be easier to search now. If you look at the list to the right, spring flowers are at the top of the list, followed by summer flowers in the middle, and fall flowers and mushrooms are near the bottom.

My goal in making this site was to teach myself about native wildflowers in my home area.  An added benefit would be to help someone else (–maybe you?) learn the same. Drop me a note if you have a comment or question, and please feel free to correct my I.D. work if you think I’ve got something misidentified. This is a hobby for me and I’m always learning.

If you arrived here because you are looking for information about a specific plant, try using the SEARCH widget in the right sidebar. Common names and latin names can be entered there. If you would just like to browse what is on the website, try scanning the archive in the right sidebar.

Most of my posts contain photo gallery/slideshows, so please be sure to click on the gallery to open a larger viewer.

Prince’s Pine

Lycopodium obscurum or Dendrolycopodium obscurum

The is the last of three New Year’s posts about local varieties of clubmoss.

Prince’s Pine (sometimes called Ground Pine, Princess’s Pine, or Flat-branched tree clubmoss) is an evergreen beauty.  Thanks to branching, it is a tad bushier than Ground Cedar, so each individual plant ends up looking like a tiny hemlock or pine tree. The “leaves” of the plant are best described as scalelike.

Prince’s Pine

Like the other clubmosses, the reproductive structure of Prince’s Pine is the club-like strobilus. The strobili are borne at the tip of the shoots and branches (see photo) of the plant. Each one will produce a cloud of spores in the fall.

Last November I came across several stands of Prince’s Pine near Pandapas Pond. While trying to take some photos, I noticed that the spores were easily released when I brushed my hand across the fruiting bodies. In the photos below, you can see the dust that was released when I did this. It was an impressive show!

Clubmoss spores were once collected and used as “flash powder” to produce bright light for photographers and magicians. Apparently, a little pinch of “Lycopodium powder” will produce quite a bit of light if ignited. Check out this crazy 2-minute video that demonstrates this and other strange qualities of Lycopodium spores:

Clubmoss populations have been threatened by over-harvesting for Christmas decorations. This practice is not as common today as it once was, but it still goes on. A stand of Prince’s Pine can take years to reach maturity, so it cannot tolerate repeated harvesting.

Ground Cedar

Diphasiastrum digitatum or Lycopodium digitatum

Clubmosses (Lycopdodiaceae) are ancient evergreen perennials that can be spotted easily in the winter woods when all the other forest floor plants are “sleeping”.  They have reproductive structures that are shaped like clubs, hence the name. When I was a college student in the way-back-when, the clubmosses were all called “Lycopodiums” because they shared a common taxonomy. Today the group has undergone significant taxonomic revision resulting in several new genera, but the term “Lycopodiums” persists as a way to refer to this unique group of plants.

The most common clubmoss in my part of Virginia is called ground cedar or running cedar. Other common names for it are fan clubmoss and bears paw. This is an exceptionally beautiful evergreen plant that forms large colonies and offers a welcome reprieve to the winter-weary eye. As the various common names suggest, the greenery looks somewhat like cedar boughs. The leaves are flattened along one plane, waxy to shiny, and dark green. The plants are 4 to 8 inches in height and spread by runners above the ground. Fallen pine needles or leaves often obscure the runners.

As I noted in a previous post about another species of clubmoss, shining clubmoss, reproduction in this group of plants involves a complicated “alternation of generations” between sporophytes and gametophytes. Of the two generations, the most visible is the sporophyte generation. The above-ground “plant” that you see is the sporophyte and it produces several tall club-shaped structures called strobili. The strobili resemble tall candles on a stick. Ripened spores are released from the strobili when the wind blows or when rain or an animal physically disturbs them. This usually happens in late summer or fall. If you are lucky enough to see this, you’ll be amazed at how many spores can be produced by a stand of groundcedar!

Long ago, Native Americans discovered that clubmoss spores produce bright light when burned. That’s because the spores contain a lot of fat. Believe it or not, “Lycopodium powder” was later used by photographers to produce a flash a light before taking a picture! It was even used in fireworks! Lycopodium powder is still collected today for various commercial uses.

A wonderful natural history article about clubmoss was written by Marion Lobstein for the Prince William Wildflower Society. You should check it out to learn more about the various ways that clubmosses have been used by humans for generations. It’s worth a read!

Shining Clubmoss

Hyperemia lucidula

It is the first of January! Happy New Year!

In Blacksburg it was a quiet day with mild temperatures and gray skies.  We took a walk in the woods in a pretty part of town, just at the foot of Brush Mountain. We have a new puppy at our house, and she needs lots of exercise, so we soon left the trail and tramped directly through the woods, just to give her a bit more exercise. Grace loves dodging around over sticks and logs while exploring all of the delicious smells on the forest floor.

What really caught my eye today were the patches of evergreen clubmoss carpeting the otherwise drab woods. Seeing that reminded me that I never posted anything about clubmoss on this blog–something I have meant to do long ago, but never got around to it.  So I grabbed a few photos today and brought them home for my first post of the new year.

Shining clubmoss and ground cedar
Shining Clubmoss with Ground Cedar

Clubmosses are interesting vascular plants, because they reproduce by spores instead of by flowers and seeds. Taxonomically, they are grouped into the class Lycopodiopsida. This group includes plants that are known locally as groundcedar (or running cedar/fan clubmoss), ground pine (or Prince’s Pine), and shining firmoss. You’ll note that all these names invoke evergreen trees, probably because the clubmosses stay green all year long and have a waxy cuticle not unlike pine and fir trees. However, unlike trees, this group of plants is low-growing and spreads by above-ground runners or below-ground rhizomes.

Today, I was excited about finding Shining Firmoss, or Shining Clubmoss, mixed in with a stand of the more common ground cedar.

Wikipedia describes this unusual plant as follows:

Hyperemia lucidula (or shining firmoss or shining clubmoss) grows in loose tufts 14-20 cm long, occasionally up to 1 m long. The leaves are 7-11 mm long, narrow, lance-shaped, shiny, and evergreen. The edges are irregularly toothed. The sporangia (spore cases) are nestled in the bases of the upper leaves.

The roots of this plant grow from a creeping, branching, underground rhizome.

Its habitat includes rich, acid soils in cool, moist coniferous and mixed hardwood forests, bog and stream edges, and hillsides. They occasionally grow on cliffs and ledges and on shady, mossy, acidic sandstone.

The specific name lucidula comes from the Latin and means “shining“. This is in reference to the plants bright, vivid green color.”

Wikipedia’s description sounds pretty accurate, so I’ll just stop right there!  Keep an eye out for this cute little clubmoss on your next winter hike!

Update April 2017: Spotted some shining clubmoss in the Rock Castle Creek gorge last weekend!
