in the spring, before trees leaf out and shade the forest floor, and when the ground
is nutrient-rich and moist, spring ephemerals – wildflowers that bloom and
disappear within a month or two – appear.
These beautiful woodland wildflowers take advantage of this time of year,
before competition begins in earnest.  In
order of appearance, the photographs are of:
BLOODROOT, Sanguinaria canadensis; BLUE COHOSH, Caulophyllum
thalictroides; CUT-LEAVED TOOTHWORT, Cardamine concatenata; DUTCHMAN’S
BREECHES, Dicentra cucullaria; HEPATICA, Hepatica nobilis; LARGE-FLOWERED
BELLWORT, Uvularia grandifolia; PURPLE TRILLIUM, Trillium erectum; TRAILING
ARBUTUS, Epigaea repens; TROUT LILY, Erythronium americanum; WILD GINGER,
Asarum canadense.
