The croton (Codiaeum variegatum) appears to possess it all: colorful foliage, nearly limitless leaf forms, and even a cultish following. But these plants have a drawback: They’re difficult to please indoors. In their native habitats, crotons like humid, warm conditions with dappled light and plentiful water. the first challenge when growing them indoors is maintaining the perfect temperature—when it’s too cold, they begin losing leaves. However, crotons are well well worth the effort because well-grown croton is an explosion of color.
