Rock harlequin

Capnoides sempervirens, rock harlequin or pink corydalis, is an annual or biennial herb in the Papaveraceae family (formerly placed in Fumariaceae) and is the sole species of the monotypic genus Capnoides. The plant is native to rocky, often fire-disturbed woodlands and outcrops across northern North America from Newfoundland to Alaska and southward through the eastern United States. Stems are erect, slender, and glaucous, reaching 20 to 80 centimetres in height. The leaves are alternate, bluish-green, and finely dissected into small oblong lobes, contributing to a delicate ferny appearance. Flowers are produced in loose drooping panicles from late spring into autumn; each tubular zygomorphic blossom is pink with a yellow tip and one spurred outer petal, measuring about one to one and a half centimetres long. The slender capsular fruits bear small black seeds with fleshy elaiosomes that promote ant dispersal.
