Description

Thaspium trifoliatum, commonly called meadow parsnip, is a branched, generally upright perennial growing 12-30- tall on ridged stems. Plants are native to eastern North America from Minnesota to New York south to Texas and Florida with concentrations found in the Mississippi River valley. In Missouri, it is typically found on prairies, rocky open woods, thickets and along streams (Steyermark). Small yellow flowers in compound umbels bloom from mid to late spring. Winged fruits appear in mid to late summer. Plant is very similar to Zizia aptera, except the middle flower in each umbel is stalked and fruits are winged not ribbed. Heart-shaped basal leaves are usually undivided, and stem leaves are trifoliate and toothed with ovate leaflets to 2- long.
