Flora of the Southeastern United States

Daucus pusillus Michaux. Common name: American Queen-Anne's-lace, American Carrot, Rattlesnakeweed, Seed-ticks. Phenology: Apr-May; May-Jun. Habitat: Rocky prairies, open woodlands, pastures, fields, roadsides, waste places. Distribution: Widespread in Southeastern United States, north to NC and MO; also distributed on the west coast of North America and south into n. Mexico; the species also occurs in s. South America, in Chile, Argentina, s. Brazil, and Uruguay, where it is considered native. There is perhaps doubt that this species is native in North America, at all. It should be expected in the lower Piedmont of NC and in the Coastal Plain of se. VA, which it closely approaches. Robert Wright has collected this species as a waif in Henrico County, VA (Wright et al. 2023). The native distribution of this species is speculative.

ID notes: This (allegedly) native carrot is smaller and less branched than the ubiquitously naturalized D. carota, and the involucre held bowl-like under the compound umbel and extending beyond it in flower and to about its edge in fruit is a distinctive gestalt.

Origin/Endemic status: Native
