About Hairy-leaf Tylecodon

Tylecodon hirtifolius · also called Hairy-leaf Tylecodon, Hairy-leaved Tylecodon · houseplant

A low, spreading succulent shrublet from the arid regions of South Africa, notable for its densely glandular-hairy, oblanceolate leaves and yellowish-green tubular flowers in mid-summer. Growing to 30 cm, it thrives in full sun with sharply draining soil. Toxic to pets and people — contains bufadienolide compounds; handle with gloves.

Preferred mix: Sandy or rocky, sharply draining succulent mix

Watch for — Root rot from summer watering: Watering during summer dormancy is the primary cause of death. The plant signals readiness to grow by pushing new leaves in autumn — only begin watering then.
