Pale Corydalis loves a cool, moist home; it ranges across the continent within the Dominion of Canada, comes down into New England, and wanders along the mountain tops to North Carolina. The blossoms are odd, little, pink sacs with yellow mouths, hanging upside down along the tip of a slender stem.

Their appearance makes clear their family relationship; they are cousins of the Dicentras but seem to possess only part of the family equipment; in fact each looks like a flower cut in half. The general effect of the plant is extreme delicacy.

The Golden Corydalis, Corydalis aurea, blooms earlier than the pink species and is a denizen of rocky woodland banks, and ranges from Quebec to the Mackenzie River and as far south as Wisconsin and Pennsylvania. It is reported from northern Ohio, but is rare. The flowers are golden yellow and the outer petals ridged on the back. The seed-pods look beaded, not erect and straight like those of its pink sister. The blooming period extends from March to May.
