Amaranthus hypochondriacus is an ornamental plant commonly known as Prince-of-Wales feather [3] or prince's-feather. [4] [5] It is called quelite, bledo [6] and quintonil in Spanish. [7] [8]
A. hypochondriacus is a vigorous, upright plant that typically reaches 40–200 cm (15–80 in) tall. [9] It is often grown for its flowers, which appear in dense, catkin-like inflorescences in the summer and autumn. They are usually deep purplish-red, but may be yellow-green. [10] These give way to dry fruits, about 1.5–3 mm (1⁄16–1⁄8 in) long, that split open when ripe. [11] The fruits contain smooth, shiny seeds that may be subglobose to lenticular, either whitish-pink or dark reddish-brown to black, and 1–1.4 mm (3⁄64–1⁄16 inch) in diameter. [12] The leaves are simple and alternately arranged, with entire margins. [11] They are rhombic-ovate to broadly lanceolate in shape, about 4–12 cm (1+1⁄2–4+1⁄2 inches) long and 2–7 cm (1–3 inches) wide, borne on long peduncles. [12]
Originally endemic to Mexico,[ additional citation(s) needed ] there is near certainty that A. hypochondriacus is the common ancestor to the genus Amaranthus , but the later domestication of groups remains unclear. There has been opposing hypotheses of a single as opposed to multiple domestication events of the three grain species. [13] [14] There is evidence of phylogenetic and geographical support for clear groupings that indicate separate domestication events in South America and Central America. [13] A. hybridus may derive from South America, whereas A. caudatus , A. hypochondriacus, and A. quentiensis are native to Central America and elsewhere in North America. [13] [14]
In temperate regions, it is cultivated as a half-hardy annual plant. Numerous cultivars have been selected, of which 'Green Thumb' [15] and 'Pygmy Torch' [16] have gained the Royal Horticultural Society's Award of Garden Merit. It grows best in well-drained soils in full sun, and is suitable for USDA hardiness zones 3–10. It may be susceptible to aphids. [10]
In Africa and El Salvador, like many other species in the family Amaranthaceae, it is valued as source of food. [17] The leaves and seeds are very nutritious and have a mild flavor. [9] The seeds also contain phenolic compounds. [18]
