kalanchoe

Kalanchoe is a genus of about 125 succulent flowering plants in the family Crassulaceae, native to Madagascar and tropical Africa. It includes evergreen perennials and a number of cultivated hybrids. The best-known species in cultivation is Kalanchoe blossfeldiana, a compact flowering plant widely grown for decorative winter blooms.

Leaves are typically thick and fleshy; margins may be smooth or scalloped. Several species form plantlets along the leaf margins, a trait once grouped under the name Bryophyllum. Flowers appear in dense inflorescences and are commonly red, pink, orange, yellow, or white; Kalanchoe blossfeldiana, in particular, is valued for its bright winter clusters.

Cultivation: They prefer bright light and well-draining soil and should be watered sparingly, allowing the soil to dry between waterings. Protect from frost; average indoor temperatures of 60–85°F (15–29°C) are suitable. Fertilize lightly during the growing season.

Propagation and varieties: Propagation is easily accomplished by leaf or stem cuttings; many Kalanchoe species also produce plantlets on leaf margins. K. blossfeldiana has many cultivars and hybrids used in horticulture.

Toxicity and pests: Kalanchoe species contain cardiac glycosides and can be poisonous to pets and humans if ingested. Common pests include mealybugs, aphids, and scale; overwatering can lead to root rot.

Uses and notes: Beyond ornamental use, some species have traditional medicinal uses in certain cultures, though care is advised due to toxicity. Kalanchoe is popular as a indoor flowering plant and decorative succulent in homes and gardens.
