A Succulent Subshrub

Kalanchoe sexangularis is a succulent subshrub in the family Crassulaceae. It belongs to a genus that spans annuals, biennials, perennials, shrubs, and even trees, all sharing fleshy foliage and tubular, four-lobed flowers.

Southern African Native

This species comes from a stretch of southern Africa running from southern Zambia up to northern KwaZulu-Natal, taking in Zimbabwe, Mozambique, Eswatini, and neighbouring provinces. It grows there in a seasonally dry tropical setting. It has since been introduced further afield, turning up in Kenya, Spain, and Tunisia.

Sun And Sparing Water

Like other kalanchoe, this one wants a sunny spot, whether indoors or out, and only needs watering once the soil has gone properly dry to the touch. It is a low water need, high light plant, so err on the side of restraint with the watering can. Handle the stems gently when moving or repotting, as kalanchoe branches are tender and snap easily.

ToxicityAuthoritative · species

Toxic to cats & dogs
