Grow in full sun for best foliage color; plants may require staking if grown in partial shade, and their color will be less vibrant. (Plants grow best in the partial shade in the West.) Moist but well drained soil. Pinch plants to encourage them to be bushy and more compact. Hardy to Zone 10 (30 degrees F) but not long lived. Plants can be overwintered indoors in a sunny, south-facing window.
