Kalanchoe
Kalanchoe blossfeldiana
Family Crassulaceae
Est. zones 10-12

The grocery-store flowering succulent that blooms for months on a sunny sill with near-zero care. To rebloom it, give it 6 weeks of long dark nights in fall (like a poinsettia) — that short-day trigger sets new buds. Nearly unkillable by underwatering; killed easily by overwatering.
