Croton (Codiaeum)

Other plants pale beside the flashy croton. The hundred-plus varieties dazzle with different leaf colorations and shapes. The one shown combines spots and streaks of green, red, pink, yellow, black, with flushes of orange.

Light

If crotons don’t get strong light-even full sun-for at least four hours a day, they will turn green and lose their usual rainbow colors. Ful coloration will return if you summer your plant outdoors when the sun is strong.

Water

Crotons like moist, but not wet soil at all times. They react adversely to hot, dry conditions and may drops leaves, so provide as much humidity as possible by misting daily.

Special Help

Use a general-purpose potting mixture. Feed every other month from early spring trough midsummer. Air layer or take stem cuttings in spring or summer.
