Flowering spring-early summer. Floodplain forests, swamps, wet-mesic coniferous or broadleaf woods, alpine meadows, pastures, moist areas in sagebrush or desert washes; 50-2600(-3200) m; B.C., N.S., Ont., Que.; Calif., Colo., Conn., Del., D.C., Idaho, Ill., Ind., Iowa, Ky., La., Md., Mass., Mich., Minn., Mo., Mont., Nev., N.J., N.Y., N.Dak., Ohio, Oreg., Pa., Tenn., Utah, Vt., Va., Wash., W.Va., Wis., Wyo.

The stems of Floerkea proserpinacoides have a spicy flavor and are eaten in salads. A flower of F. proserpinacoides is the logo for the Flora of North America project.

Annual herb 5 - 30 cm tall Stem: weak, decumbent to somewhat upright, hairless. Leaves: alternate, compound or deeply divided into three to seven segments 0.5 - 2 cm long, each segment linear to elliptic or inversely egg-shaped. Flowers: white, with three lance-egg-shaped sepals 2.5 - 6 mm long and three 1 - 2 mm long petals that are inversely egg-shaped. Fruit: separating into tiny, egg-shaped to spherical, warty segments (mericarps).

Similar species: No information at this time.

Habitat and ecology: Common in sugar maple woods, often near springy creeks.

Occurence in the Chicago region: native

Etymology: Floerkea is named after the German botanist Heinrich Gustav Floerke (1764-1835). Proserpinacoides means "like Proserpinaca."

From Flora of Indiana (1940) by Charles C. Deam

Locally abundant in thick woodland in rich, moist soil, usually associated with sugar maple, beech, white oak, and white elm. We have no records for the area south of Sullivan County. This little annual when removed from the woods to a rich, shady flower garden will persist as a weed.
