distribution_en:

description_en: Genus of 28 species of vigorous, erect to spreading, usually prickly annuals, perennials, and one shrub, from scrub and wasteland in S. and S.E. USA, Central America, and the West Indies. The fleshy roots produce large clusters of mostly basal, entire to deeply lobed, smooth to prickly, glaucous leaves. Paper-thin, poppy-like, white, yellow, or mauve flowers are borne singly or in corymbs in a long succession from summer to autumn. The flowers are followed by very prickly seed pods; the seeds may cause severe discomfort if ingested. The stems, when cut, exude a pale yellow to orange latex. Although some species are perennial, they are often cultivated as annuals. Grow in a gravel garden, or in a sunny mixed border. Prickly poppies self-seed freely.
