COW PARSNIP Heracleum lanatum, Michx. Other English names: Woolly Parsnip, Masterwort. Native. Perennial. Propagates by seeds. Time of bloom: June to July. Seed-time: August to September. Range: Labrador to Alaska, southward to North Carolina, Mis- souri, Utah, and California. Habitat: Moist ground; waste places, sides of ponds, ditches, and streams. One of the largest of umbellifers, well named for Hercules, the giant. The huge, fleshy root sends up a stalk four to eight feet tall, sometimes two inches thick at base, deeply ridged and grooved, and wrapped in matted white hair. Leaves large, ternately compound, the segments broadly ovate, sharply toothed, and cut- lobed, stalked, somewhat thin for their size, densely covered on the under side with a network of white, woolly hair; petioles stout, much inflated, and clasp- ing at base. The whole plant has a disagreeable odor, especially when bruised, and the juice is extremely acrid; that of the root, when applied to the skin, will quickly draw. 213. — Cow Parsnip (Heracleum lana- tum).
