On the Last Day of Winter

Today is the first day of meteorological spring* (astronomical spring is still three weeks away), but as of yesterday, the 28th of February, the wildflower show had already begun along the Potomac. Barely.

Claytonia virginica (spring beauty; Montiaceae)

Just a few dozen of these were up in sheltered locations.

This one specimen of Packera aurea (golden ragwort; Asteraceae) already had well-developed buds. Often this species will retain leaves through the winter, and many low-lying leaves were visible, but I saw none of the tall growth yet. In the same location last year just a few flowers were open on March 23, with peak bloom about April 13; in 2015, I saw the first ones March 24, with peak bloom in mid-April.

Erigenia bulbosa (harbinger-of-spring; Apiaceae)

More about this in an upcoming post. Can you see it sheltering there under the maple leaf? That’s one plant with about 14 flowers!

A few alien species are starting to bloom: Veronica hederifolia (ivy-leaved speedwell) and Cardamine hirsuta (hairy bittercress).

And, I saw one clump of Mertensia virginica (Virginia bluebells) foliage emerging, but that makes a boring photo.

Just Around the Corner

A few days ago a friend reported seeing spring beauty (Claytonia virginica) blooming on the Billy Goat C trail. Damn, that’s early!  Think I’ll head out tomorrow and have a look, because it has been literally months since I last photographed a wildflower.

<—not my friend’s picture; one of mine from last year




Except for this one: trailing arbutus (Epigaea repens), a low-growing evergreen in the Ericaceae. Please forgive the picture quality; it’s a quick iPhone snapshot to remind me to go back and look for it again, because it’s already budding up, and I’ve never seen one in bloom. If I manage to catch it flowering I will of course be writing about it here.

Nerd moment: I just realized it’s time to start my 2018 spreadsheet.


There are a lot of pink wildflowers in the Maryland Piedmont. As with blue and purple, “pink” can vary quite a bit, from almost white to practically red.

Claytonia virginica (spring beauty; Portulacaeae)

One of our earliest ephemerals, blooming as early as late February after a warm winter, and lasting into May. In woodland soils almost everywhere. Usually white with a pink tint.

Mertensia virginica (Virginia bluebells; Boraginaceae)

Virginia bluebell buds start violet and turn pink before opening blue, except when the flowers are pure white or pure pink. I visit this stand every year just to make sure that the flowers really are all pink from start of bloom through senescence. They are.

Cercis canadensis (redbud; Fabaceae)

Around here, this understory tree usually blooms in April, when other trees are just starting to blush green. It’s a beautiful effect, though maybe not as stunning as…


Rhododendron periclymenoides (pinxter azalea; Ericaceae)

I don’t know that we have a more stunning native shrub than this. I’ve seen it in rocky, wet areas in Rachel Carson Conservation Park and Sugarloaf Mountain; it blooms in mid spring.

Silene caroliniana ssp. pensylvanica (wild pink; Caryophyllaceae)

Look for the flowers in early April to late May. These low-growing plants are often found in dry, rocky soils in open woodlands. There are several stands near Carderock.


Valeriana pauciflora (long-tube valerian, large-flower valerian; Valerianceae)

This delicate plant (S1/endangered) has an explosive inflorescence that usually opens in May. A great photo has always eluded me, despite hours and hours and hours of trying, because the plants bloom in the deep shade of dense woods. Shade is the bane of photographers. Maybe this year.

Hibiscus laevis (halberd-leaved rosemallow; Malvaceae)

Unlike the previous species, this one likes bright, sunny riverbanks. I love how it just glows in the light! Sometimes considered a forb and sometimes as a shrub, it’s a very tall plant with stems that get somewhat woody as the season progresses; but, like a forb, it dies back to the crown in autumn. Watch for it in early to mid summer. S3 in Maryland.

Hylodesmum nudiflorum (naked-flower tick trefoil; Fabaceae)

The tick trefoils can be tricky to identify, but this one stands out because the flowers are borne on leafless stems. The genus Desmodium was recently split, with some species placed in a new genus, Hylodesmum. According to the excellent gobotany site, species in the former as sun-loving, and species in the latter are shade-loving.

Desmodium paniculatum (panicled tick-trefoil; Fabaceae)

This one blooms in mid to late summer. It grows in moist to dry soils in sun to part shade, and does well in disturbed areas.

Lespedeza virginica (Fabaceae) Not seen as often as the alien invasive L. sericea, this species grows in dry areas, blooming in mid to late summer.

Asclepias incarnata (swamp milkweed; Apocynaceae)

If you want to spend hours being entertained by bees and butterflies, park yourself in front of a stand of milkweeds. I’ve seen them blooming in wet soils in sunny areas from late June to late August.

Persicaria amphibia (water smartweed; Polygonaceae)

Or, as I prefer to call it, DPP (damn pink persicaria). I’m fairly certain I’ve ID’d it correctly. Sometimes I’m not particularly attracted to a species until I sit and study it awhile and try to get good close-up pictures. So it was with this one. Click on the pic to see it larger. It’s pretty up close!

Sabatia angularis (rosepink; Gentianaceae)

I’ve only seen this plant once, in the shade of a small shrub even though it’s a sun-loving species. Watch for it in dry soils in open places. What a beautiful color.

So Close…

20150324-_DSC0110 Technically, spring is here in the mid-Atlantic piedmont, but it sure doesn’t feel that way.  I went out today in search of something – anything – blooming.  Found two aliens (lesser celandine and one of the speedwells) and two natives (I’ll post the other one tomorrow).  If the skies hadn’t been overcast this spring beauty might have opened up all the way.
