Circium pumilum, Spreng. (Carduus odoratus, Porter)

Native. Biennial. Propagates by seeds. Time of bloom: July to September. Seed-time: August to October. Range: Maine to Pennsylvania and Delaware. Habitat: Pastures, and borders of fields.

Root round, thick, solid, often branching, the autumn tufts of leaves large and spreading. Stem one to three feet tall, stout, hairy, with few branches, very leafy. Leaves oblong lance-shaped, sessile or partly clasping, softly hairy, green on both sides, pinnatifid, the lobes short, triangular, very prickly-toothed. Heads purple, pale lilac, or sometimes nearly white, very large, often three inches broad, very sweet-scented; bumblebees are nearly always probing them for nectar, and in the writer's childhood it was a custom of country children to strip away the bracts, pull the florets from the receptacle, and eat the sugary nectaries like taffy; the heads are solitary, terminal,, usually subtended by involucrate clusters of small leaves, the outer bracts of the involucre sometimes slightly glutinous on the back, prickly-tipped, the inner ones unarmed and very slender. (Fig. 355.) Means of control the same as for the Common Thistle.
