Amaranthus tricolor (Joseph's coat)

Amaranthus tricolor, commonly known as Joseph's Coat, is an ornamental annual in the Amaranthaceae family native to tropical Asia. It is grown for its vividly colored foliage rather than its flowers, forming an upright plant typically 1 to 3 ft tall. Leaves are broad and soft-textured, displaying striking combinations of green, yellow, orange, and red that often intensify toward the upper growth. The overall effect is bright and multicolored, with new leaves providing the strongest contrast.

This species prefers full sun and well-drained soil with regular moisture. Growth rate is fast in warm conditions. Cold tolerance is low, as it is a true annual and sensitive to frost. Amaranthus tricolor is suitable for garden beds, borders, and container growing, where its foliage provides strong seasonal color.
