I had a quick look around the Carderock area on Friday (March 29), and saw the following plants blooming or budding. Also had fun taking closeup shots.
Arabidopsis lyrata (lyre-leaved rockcress): a few flowers –>
Boechera laevigata (smooth rockcress): buds
Cardamine angustifolia (slender toothwort): buds
<–Cardamine concatenata (cut-leaf toothwort): flowers
Claytonia virginica (spring beauty): lots of flowers
Dicentra cucullaria (Dutchman’s breeches): a lot of buds, a few flowers
Dirca palustris (leatherwood): full bloom –>
<–Erythronium americanum (trout lily): gobs of leaves; 5 flowers
Lindera benzoin (spicebush): flowers
Mertensia virginica (Virginia bluebells): lots of buds, just a few open flowers –>
<–Micranthes virginiensis (early saxifrage): full bloom
The next few weeks should be spectacular.

That rockcress looks very familiar, besides resembling our native species. Did you feature it earlier? I should see how it compares to ours. I sort of ignore ours just because it is not horticulturally significant. We do not plant it, and it is not common in the wild.
Oh bother, some of the pictures are not opening. Things are running slower here.
Smooth rockcress, spring beauty, Dutchman’s breeches and spicebush are not opening.
Loving the little trout lily. Beautiful
