This time of year, some native wildflowers in our woodlands, known as “spring ephemerals,” get a reproductive jump on their larger neighbors, then disappear. As Rappahannock resident and spring-ephemeral fan Bruce Jones put it in a recent email, “The spring dudes have a timetable: get out of the ground, bloom, get pollinated, and go to sleep when the leaf canopy closes in.”
Catching these wildflowers at their most beautiful is tricky. Bloom time depends on several factors, with temperature and exposure to sun key among them. These factors can vary with location, especially at different elevations. The length of bloom period also varies depending on the species, with some flowers coming and going so fast it’s easy to miss them. The bloodroot near my house bloomed and disappeared in a little more than a week. With the long, cold winter and fitful start of spring this year, timing walks to see spring ephemerals in bloom is even trickier than in most years. The best approach, I find, is to go into the woods as often as possible to see what’s blooming.
Some of the most sought-out spring ephemerals are peaking or will start soon: Virginia bluebells (Mertensia virginica), trillium and ladyslippers. Last Sunday (April 19) I found bluebells along the Rappahannock River in the rich floodplain they prefer, their delicate beauty offsetting the river’s torn-up banks, ravaged by the winter and spring storms. Shenandoah River State Park (in Bentonville) offers the mile-long Bluebell Trail for seeing these and other spring ephemerals.
Depending on the species, ladyslippers (in the orchid family) and trillium typically start their show the last week in April. Thompson Wildlife Management Area (WMA), on the western border of Fauquier County, is famous for its trilliums, especially the large white trillium (Trillium grandiflorum). Ladyslippers, including the yellow ladyslipper (Cypripedium parviflorum) and the more common pink ladyslipper (Cypripedium acaule), also grow there.
Commenting on reports from someone who lives near Thompson, MidAtlanticHikes.com says that, along Thompson’s Trillium Trail there are “literally millions of Trillium…, thousands of Showy Orchis (Galearis spectabilis or Orchis spectabilis) and, if you know where to look, some very impressive Yellow Lady Slippers.” On the website’s Thompson WMA page is an excellent, downloadable U.S. Geological Survey topographic map that should help with the hunt — “Yellow Ladyslippers” set in large blue type with an arrow pointing to the spot. It also shows where to park for the Trillium Trail.
One option for seeing Thompson’s trilliums and ladyslippers is a bird walk by the Northern Virginia Bird Club on May 9, which also offers the chance to see many of the birds now migrating through or into our area to breed. Even if you miss the trilliums and ladyslippers this year, Thompson is still worth visiting for its great wildflower-viewing opportunities throughout the bloom season.
Shenandoah National Park is also a great place to see spring ephemerals. Its website has a page devoted to the park’s wildflowers that includes a downloadable chart of the most common ones in the park, organized by bloom times. The park’s 29th annual Wildflower Weekend is May 9-10 (download a schedule at nps.gov/shen/upload/Wildflower.pdf).
When I asked Bruce about the progress of his spring ephemerals in an email last week, he wrote back that celandine wood poppy (Stylophorum diphyllum) was in full bloom, twin leaf (Jeffersonia diphylla) was through with its bloom, and Hepatica were also about through flowering. However, he added, other spring ephemerals “are just popping through the leaf litter.”
“For the next 14 days something will be in bloom,” he says, “and it changes about every day.” (Check out Bruce’s spring ephemerals on his Jones Nature Preserve website.)
Where I live, I have yet to find some of the more spectacular spring wildflowers, such as trillium or ladyslippers, but I thoroughly enjoy the bloodroot that blooms throughout the forest here every year, brightening up the forest floor and offering hope that spring has finally begun. The more delicate wood anemone (Anemone nemorosa) is now blooming in the wetland down near the ponds, and the tiny star chickweed (Stellaria pubera), which started blooming in early April, is everywhere in the woods and should continue into June, which makes it not that ephemeral, but certainly a joy to see.
