|discussion=<p><i>Amaranthus tricolor</i> is widely cultivated as a garden plant for its showy, often variegated, distal leaves of striking colors—red, scarlet, maroon, purple, yellow, cream, and green. Other cultivated varieties with green leaves are sometimes cultivated as a potherb. Escaped plants sometimes occur near places of cultivation; we have no evidence of widespread establishment.</p>
