Amaranthus hypochondriacus (am-uh-RANTH-us hy-po-kon-dree-AH-kus)

Family: Amaranthaceae Native

Amaranthus hypochondriacus , or Prince's Feather, is an herbaceous annual or short-lived perennial plant with showy feathery red flowers often grown as a ornamental. It is commonly viewed as a weed on wasteland as well as on agricultural land. Amaranthus is monoecious (meaning individual flowers are either male or female, but both sexes can be found on the same plant). It is pollinated by wind. Prince's Feather prefers well-drained fertile soil in full sun. It is often cultivated, especially in tropical areas, for its edible leaves and seeds, though it is less often seen in northern climates because it is late maturing.The plant tends to have a clumping habit. Diseases, Insect Pests, and Other Plant Problems: Aphids may be a problem. Amaranthus are not poisonous, but when grown on nitrogen-rich soils they can concentrate nitrates in the leaves. Nitrates are implicated in stomach cancers, blue babies and other health problems. It is inadvisable, therefore, to eat this plant if it is grown on land where chemical fertilizers are used.
