When grown outdoors, Coleus plants will survive and grow in the sun, but foliage color is much more intense when grown in light shade or when grown under ultraviolet light indoors. Sow seeds in spring or purchase small seedlings and transplant to beds after temperatures reach 50ºF. Space plants 12 inches apart and pinch back when plants are 4 to 6 inches to encourage bushier growth. Apply fertilizer (10-10-10) once per month
Seedlings are less brilliant in color when young, intensifying in color as they age.
