Introduced. Annual. Propagates by seeds.

Time of bloom: June to August.

Seed-time: July to September.

Range: Maine, Ohio, Michigan.

Habitat: Fields, waste places.

Not a common plant as yet in this country, and but a few years ago listed as only to be found at one point on the coast, a "fugitive" from Europe. It is small, with a fleshy taproot from which spring several naked stems, three inches to a foot high, sometimes simple but usually branching near the top, full of milky and bitter juices, thickened and hollow just below the heads. Leaves all basal, in a flattened rosette, two to four inches long, spatulate, hairy, coarsely and sharply toothed, tapering to margined petioles. Heads yellow, about a half-inch broad, the bracts of the involucre in one series, equal, thickened, narrow, pointed, and strongly keeled, lengthening after flowering and curving over the achenes, which are ovoid, finely ribbed, and without pappus. (Fig. 361.)

Means Of Control

Prevent seed production by close cutting while in early bloom.
