Pseudolithos migiurtinus (Chiov.) P.R.O. Bally
Ceropegia migiurtina, Lithocaulon sphaericum, Pseudolithos sphaericus, White-sloanea migiurtina
Pseudolithos migiurtinus is a dwarf succulent with a knobbly, leafless, usually solitary stem with roundish tessellations. The stem can reach 4.8 inches (12 cm) in height and 2.6 inches (6.5 cm) in diameter, at first subspherical to pyramidal, four-angled, or cylindrical with age. It varies in color from light green to reddish-brown.
The stem angles bear four vertical lines of smaller and protruding tessellations, from which arise short subspherical to cylindrical lateral shots bearing clusters of cupule-shaped flowers that appear in spring and fall. The flowers are dark red to dark maroon and up to 0.3 inches (0.7 cm) in diameter. Fruits are paired, up to 3.2 inches (8 cm) long follicles with tiny dark brown seeds.
Pseudolithos migiurtinus is native to Somalia.
USDA hardiness zone 11a to 11b: from 40 °F (+4.4 °C) to 50 °F (+10 °C).
How to Grow and Care
Stapeliads are relatively easy to grow. However, they should be treated as an 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. They require a reasonable amount of sunlight to promote flowering and maintain a well-shaped plant. Very shady positions will produce very poor flowering.
Stapeliads come from climates where they survive extremely high temperatures in the summer months, so most growth is in spring and autumn, with flowering in autumn when the weather starts to cool down. Water in moderation when needed in the growing season, ensuring the soil is fairly dried out between waterings. Do not water between November 1 and March 1. Fertilize lightly, if at all, to prevent overly lush and weak stems.
The easiest and best way to propagate Stapeliads is from stem cuttings which can be taken virtually throughout the year. Seed is also a method of propagation.
