Botanical illustration of Kalanchoe
Succulent · Kalanchoe blossfeldiana

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.

Questions

Kalanchoe questions, answered straight.

Is kalanchoe safe for kids and pets?

With care. Toxic to cats/dogs — bufadienolides (cardiac glycosides), so ASPCA flags possible abnormal heart rhythm alongside the usual GI upset Site it accordingly if children or pets roam the garden. This is general reference, not medical or veterinary advice — call a vet or poison control if something has actually been eaten.

How do you propagate kalanchoe?
