Synonym(s)
Trichocaulon decaryi, Ceropegia pilosa
Scientific Classification
Family: Apocynaceae
Subfamily: Asclepiadoideae
Genus: Stapelianthus
Origin
The native range of Stapelianthus pilosus is in the far south of Madagascar.
Description
Stapelianthus pilosus is a small, highly branched succulent that forms a clump of green to dark brown stems densely covered with tubercles, each tipped with a soft bristle. The stems are erect, ascending, or decumbent, cylindrical, and can grow up to 12 inches (30 cm) long and 0.5 inches (1.3 cm) in diameter. Tubercles emerge green in spring but quickly assume their bright, eye-catching hues.
The flowers, which have five triangular lobes, are yellow with brown spots and appear in late summer and fall. They can reach a diameter of up to 0.7 inches (1.8 cm).
Hardiness
USDA hardiness zones 9a to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Stapeliads are relatively easy to grow. However, they should be treated as outdoor plants as they will easily rot indoors and cannot flower without exposure to outdoor temperature fluctuations. They should be grown under cover so that watering can be controlled. Stapeliads require a reasonable amount of sunlight to promote flowering and maintain a well-shaped plant. Very shady positions will produce very poor flowering.
These plants come from climates where they survive extremely high temperatures in the summer months. Most growth occurs in spring and fall, with flowering typically in fall as the weather cools down. In the growing season, give them moderate water, ensuring the soil is dry between waterings. Do not water between late fall and early spring.
The easiest and best way to propagate Stapeliads is from stem cuttings, which can be taken virtually throughout the year. Using the seeds is also a method to propagate Stapeliads.
