Stapelianthus decaryi Choux
Stapelianthus decaryi is a unique succulent, up to 4 inches (10 cm) tall, that forms large, compact clumps. Stems are grey-green spotted with red-brown, covered with tubercles, and up to 0.6 inches (1.5 cm) in diameter. Flowers are chalice-shaped, creamy-yellow, and maroon speckled. They are up to 1 inch (2.5 cm) across and appear in late summer and fall.
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
Stapeliads are relatively easy to grow. They should be treated as an outdoor plant 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, so most growth is in spring and fall, with flowering in fall when the weather starts to cool down. In the growing season, water in moderation when needed, making sure soil is fairly dried out 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. The seed is also a method of propagation.
