From Old World tropics. Kalan- choes have fleshy, typically green leaves and bell-shaped flowers; they are used principally as houseplants but can be grown outdoors year-round where winters are mild and frost free. Site indoor plants in a south-facing window and let them go fairly dry between waterings. Feed with a general-purpose liquid houseplant fertilizer monthly from spring until fall. Reduce watering in winter, but don't let soil dry out so much that leaves wither.
