Amaranthus tricolor L.
Common Name: AMARANTH
Coefficient of Conservatism: *
Coefficient of Wetness: 3
Wetness Index: FACU
Physiognomy: Ad A-Forb

A species domesticated from eastern Asia and collected by O. A. Farwell at Detroit (Wayne Co.) in 1912, presumably as an escape from cultivation. Strains with blotched and colored leaves are cultivated under the name of Joseph’s Coat.

Specimens of A. tricolor might run in the key to the first two species because of the prominent axillary flower clusters. These are, however, more prominent than in A. blitoides and A. albus, and become contiguous and crowded terminally, though they may be leafy-bracted. The erect stature of A. tricolor immediately distinguishes it from A. blitoides, and the seeds are larger than in A. albus.
