Skunk Cabbage Flowers

Skunk Cabbage flowers (Symplocarpus foetida)

Yesterday I went out with the Virginia Native Plant Society (VNPS) to a site new to me: the Cool Spring River Campus of Shenandoah University. Cool Spring was the site of a famous battle during the Civil War that took place in 1864, and was acquired by Shenandoah University in 2013 as a way to preserve the historic battlefield. The 195-acre parcel lies along the eastern shore of the Shenandoah River and contains many lovely old trees and fields.

Our excursion focused mainly on the Skunk Cabbage that is currently flowering. The Skunk Cabbage (Symplocarpus foetida), a member of the Arum family, produces a curious flower consisting of a spathe that contains a spadix, which has numerous small flowers along its surface.

This plant exhibits one botanical oddity: it is thermogenic--it can generate heat from cellular respiration alone. The flowers, which emerge in early spring, can melt snow on the ground. This allows the spadix inside the ovoid-shaped spathe to maintain a constant temperature up to 20 degrees higher than the ambient air, for optimal development of the flowers. The female flowers in each spadix mature first, then the stamens emerge, thus preventing self-pollination.

The morning started out with a bit of rain, but by afternoon, when we assembled, the rain had stopped and it was unseasonably warm--about 64 degrees. Gradually the sun came out and it turned into a beautiful afternoon. 

There wasn't much to see here--botanically speaking--except for the Skunk Cabbage, so after a while I peeled off from the group and got my sketching gear from the car while the rest went on to explore the trail along the river.

I set up right by the first couple of flowers--the stinky scent was perceptible, particularly the pollen when touched, but it was not overwhelming, thank heaven. Bees were buzzing around the flowers, despite the fact that they smell like carrion and are supposed to be pollinated by beetles or other ground insects. The colors, particularly the mottling, were challenging, and the shapes too. I spent about an hour creating my small sketch. By then the sun was coming out, but it was a bit late to rejoin the VNPS group, they were just returning from the river trail.

I continued on the trail along the river on my own. There were many lovely old trees here, many of them Sycamore maples of noble proportions, and many people were about, enjoying the first stirrings of spring. It hadn't rained for a couple of weeks, and the water was crystal-clear.

I got back to the parking lot a little after four, as the clouds were starting to move in again, and headed home. This is a promising new area for botanical sketching, I hope to return when the spring ephemerals begin to emerge.

The First Crocus


 

The first crocus of spring is a long-awaited sight, signaling the end of winter and the beginnings of early spring. This year it took place on February 24, when the temperature rose into the 60's on a sunny day. The snow and ice on the ground had begun to melt the day before, and the watering sent these lovely buds up. Others soon followed.



I'd planted some mixed crocuses under my cherry tree some years ago, but hadn't seen any these yellow ones for the last few years, so it was a surprise to find several of this feathered yellow variety sprouting, along with one lone white one. I believe the yellow ones are of the species Crocus chrythansus 'Fuscotinctus.'


Several varieties of crocus in front yard.

Crocus tommasinianus , nicknamed "Tommies," is the one species that has multiplied most prolifically in my front yard. I'd read that rodents and other pests tend to stay away from this species, and with so many voracious wild creatures around here, it has lived up to its reputation, proving to be quite resistant. Every year the display gets better.

Other early spring bulbs are starting to wake up, and soon my garden will once again be filled with flowers... I can't wait to see what the display will be like this year!

Signs of Spring

Crocus buds growing with red thyme.

A few warms rains in mid February brought out the first crocus buds in my front yard. The first crocuses are always a hopeful sign of spring, and over the years mine have been spreading nicely under the cherry tree, in spite of the voles and squirrels that eat the bulbs.

This year a few of the yellow species crocuses actually bloomed--this color seems to be the most frequently eaten by wild creatures, oddly enough.

Below is a drawing of a bunch of radishes in color pencils that I did as a demo for a workshop at the New Day Art Center in Martinsburg, WV a couple of weekends ago. It has nothing to do with spring crocus,  but when I see lovely bunches fresh radishes like these and other produce arriving to our grocery store, it seems like another wonderful sign of spring. At this time of the year when fresh flowers are hard to come by, I rely on my grocery store to find botanical specimens to use in my botanical art classes and workshops.

Speaking of the New Day Art Center, I'm offering another workshop there on March 28 and 29: "Sharpen Your Drawing Skills." Talking to other artist/instructors I find that drawing is the skill most of our students are weakest in. Drawing directly from life is a challenge, but one of the most useful skills in an artist's toolbox.

Trillium Trail 2014


VNPS members on the Trillium Trail

On the last Sunday in April I hiked the Trillium Trail at Thompson Wildlife Management Area (Thompson WMA) with the Piedmont Chapter of the Virginia Native Plant Society (VPNS). Spring is so late this year that the thousands of trilliums (Trillium grandiflora) this area is famous for were barely out of the ground; only a few blossoms here and there and a few patches in the sunnier part of the lower portion of the hill were visible. At this higher elevation the tree leaves had not begun to unfurl yet, and it was much chillier at the top of the ridge than in the valley below.

Our hike leader Sally said that at one time it was thought that the trillium flowers started out as pure white and turned pink with age, but this is actually not so. Seeing is believing, and here was the proof--many of the just-emerging blossoms were a soft pink in bud and recently-opened blossom. I've heard theories that the trilliums in this huge stand are the result of many years of natural hybridization of several species such as T. grandiflora with T. erectum, but botanically, the pink variety is classified as T. grandiflora forma roseum and wavy edges on the flower are one characteristic of this variant.

We took the side trail leading to the Appalachian Trail (AT) with Sally pointing out many interesting plants, some of which I was familiar with, and others unknown to me, including a native mustard that is the host plant for the West Virginia White butterfly (Pieris virginiensis). I didn't know that this native butterfly has been steadily declining since the 1990's, and one reason is that the butterfly seems to get confused and lays its eggs on that invasive plague, garlic mustard, instead of its host plant. The caterpillars cannot survive on garlic mustard, and when the butterfly does not reproduce, the population in those areas can be wiped out.

A lady who befriended me on the previous hike, Mary Keith, told me that the Piedmont Chapter  maintains the Trillium Trail to try to keep the garlic mustard under control, and sure enough, as we walked she and several other ladies pulled up any traces of the noxious invader we came across and bagged them to dispose of them later. Evidently garlic mustard is so programmed for survival that even after being pulled up, any flowers on the stems can set seed and spread, so the plants can't be left lying around on the ground.

Turning left onto the AT we encountered many early spring ephemerals blooming along trail: bloodroot, wild ginger, blue and smooth yellow violets, and Canada mayflower.

I looked for the Showy orchid, hoping to catch a glimpse of some and eventually I spotted one nice clump emerging by the side of the trail. The fleshy leaves formed a curious vase-like cup with the tiny flower spike bud barely visible inside.

Further down the hill we encountered a seep, full of skunk cabbage and other interesting plants, among them the false hellebore I had seen last year at Big Meadows on Skyline Drive, and another type of saxifrage with toothed leaf margins.

False Hellebore (Veratrum viride)

 At the junction of the AT with the fire road we turned left to go up the hill. Many huge trees had come down during the harsh winter, the dead trunks and branches strewn all over the ground, cut only to allow passage on the fire road. The lumber on the ground obscured most of the areas where I'd seen Yellow Lady Slipper orchids in years past, but I found a few orchid plants emerging from the leaf litter. At this stage, the plant would have been difficult to identify if I hadn't known the location

As we were approaching the end of our circular hike, near the parking area, a patch lovely of trout lilies greeted us by way of bidding our group good-bye. These plants had quite a few leaves, more than the usual two per blooming plant.

Calme's Neck

The Shenandoah River at Calme's Neck

A few Saturdays past I joined the Virginia Native Plant Society's Piedmont Chapter on a walk at Calme's Neck. This site is registered by VNPS as a unique area full of native plants, some quite unusual, and is on private land. One of the VNPS members who lives in this development hosted the group.

After driving up and around some steep curves on a gravel road for several miles, I arrived a little later than the announced 10 AM meting time. Our hike leader, Gary Fleming, a gentleman who has been mapping the flora of Virginia for the past 30 years for the Digital Atlas of the Virginia Flora, was about to conclude his introductory talk. There is probably not a corner of the state that he has not covered at some time or another. There were about 25-30 of us in the group--some of the VNPS chapter members have been visiting this particular site for the past 21 years.

We started our hike near the top of a hill and walked towards some rocky high bluffs overlooking the Shenandoah river. The just-budding trees were bare enough to allow spectacular views of the farms on the other bank and the distant mountains on the other side of the valley.



The rock ledges sheltered a variety of mosses, early Saxifrage (Saxifraga virginiensis), and ferns, among them walking fern, which I've only seen once before in Maryland.

Beyond the bluffs, the hill sloped down and the trail parallelled the river. Virginia Bluebells grew thickly along this floodplain, but with spring so late, their flower buds were still pink and rolled up tight. There were also both Dutchman's Breeches and Squirrel Corn plants here and there, and one of the ladies on the hike (they were all so knowledgeable!) explained the differences between these two very similar plants: the "breeches" of the Squirrel Corn are much tighter, resembling the Bleeding Heart, the leaves are bluer, and true to their name, the Squirrel Corn has a small underground tuber that resembles a grain of corn (we didn't dig one up to verify this).

Squirrel Corn (Dicentra eximia)

After a while the floodplain narrowed out and we turned inland to walk up a very steep hill that was covered with spring flowers. Twin leaf, a low-growing plant with star-shaped white flowers that I had never noticed before, grew all over the slope. There were also trout lilies, but only one of these in bloom. The more knowledgeable members of the group explained that trout lilies must develop two leaves before they will bloom, and the individual plants found in these woods don't do this very often, although in other regions they do bloom profusely.




Twin Leaf (Jeffersonia diphylla)

At one point on the slope I found something among the carpet of leaves that I though might be a dead bird, but upon closer examination it turned out to be a huge owl pellet, with tiny bones imbedded. It was relatively fresh, indicating a large own had been here recently--a barn owl, or something more picturesque?

Back at the top of the hill, I eventually saw our parked cars through the tree trunks, so we had hiked around in a big circle. I was among the laggards at the rear, and most of the other folks had already driven down the gravel road to have our brown-bag lunches by the river. Our picnic site was a lovely grassy spot  by the banks of the Shenandoah where the residents of this private enclave had placed a picnic table. It was nice opportunity to get to meet the other members, and quite by coincidence, one of the young ladies in the day's hike turned out to be someone I had been corresponding via Email at the botanist's office in Shenandoah National Park.

Our hostess, Blanca, had been born in Argentina, and naturally, we spoke a bit in Spanish.  As we ate our lunch, we were amused by a group of cormorants flying around on the other bank and diving into the river. I didn't know that cormorants strayed this far inland from coastal areas, but was told that they come regularly to the Shenandoah during their molting season.

All the folks I met were very congenial, and I will definitely be joining VNPS for more hikes in the future. It's a great way to get to know the many beautiful natural treasures in this area!

Spring Fever


Yesterday Herb and I got up early to begin spring cleaning in our yard. We had rented a chain saw to cut down some big branches that had broken off during the winter. Mercifully, this year's snowstorms were not as severe and there were fewer branches down than the previous winter, when we spent three weekends cleaning up the yard. We were done in a couple of hours.

In the afternoon the sun came out and the temperature rose--I noticed one crocus flower bud had poked up in my front yard, but all the others seemed to be at least a week away from any bloom. I figured that Brookside Gardens, being closer in town and warmer, is seasonally ahead, so I drove there to scout out painting locations for the coming weeks.

An expanse of mauve crocus flowers greeted me at the entrance by the Visitor's Center. Further up the path, intoxicating scents of Witch Hazel and narcissus wafted from my favorite patch of birches (see last year's posting A Host of Golden Daffodils). It wasn't quite warm enough for painting yet, but there were enough flowers to gladden the heart on this sunny afternoon.
