Amaranth
Amaranth, or more correctly Amarant (see Milton's Paradise Lost, iii. 353), from the Greek amarantos, unwithering, is the name of a large order of weedy herbaceous plants, mostly growing in dry situations in the tropics, having a crowded inflorescence of florets with dry membranous floral leaves, often coloured, as in the familiar "cockscomb," "love-lies-bleeding," and "Prince-of-Wales'-feathers."
