Description

Devil’s Backbone is a striking, low-maintenance plant known for its unique, zig-zagging stems that give it a spiky, architectural look. The plant gets its common name from the shape of its stems, which resemble a bird's back or spine. In late winter to spring, it produces small, red, bird-shaped flowers that add a dash of color to its otherwise green form. While it’s a hardy succulent that thrives in sunny, dry environments, it's also a great choice for indoor spaces where you want a plant with a bit of character.

Light requirements

Pedilanthus tithymaloides thrives in full sun to partial shade. It does best when it receives at least 4–6 hours of direct sunlight per day, although it can tolerate some shade. However, in shadier spots, the plant’s growth might become a bit more leggy, and flowering may be reduced.

Soil preferences, including pH and drainage

This plant prefers well-draining, sandy or loamy soil with a slightly acidic to neutral pH (6.0–7.0). As with most succulents, it needs excellent drainage to avoid root rot, so be sure the soil is light and porous. If growing in a pot, ensure the container has drainage holes.

Water needs

Pedilanthus tithymaloides is highly drought-tolerant, like most succulents, and doesn’t need frequent watering. Allow the soil to dry out completely between waterings, and water deeply but infrequently. In cooler months, reduce watering even further, as the plant is less active. Overwatering can lead to root rot, so it's important to avoid keeping the soil too wet.
