Echidnopsis malum (Lavranos) Bruyns
Pseudopectinaria malum, Ceropegia malum
Echidnopsis malum, formerly known as Pseudopectinaria malum, is a small succulent with grey-green or brownish stems the grow up to 15 cm long. Flowers are urn-shaped, held upright, depressed at the apex, and with a pentagonal opening. They are bright green with red streaks outside, dark purple-red inside, and have long white hairs in the lower and upper parts. The middle portion is somewhat tuberculate. The transverse wrinkling of the corolla tube is also remarkable, being more pronounced than in any other species. The corolla-lobes are triangular-ovate and very fleshy.
USDA hardiness zone 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. 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. 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 fall, with flowering in fall when the weather starts to cool down. Water in moderation when needed in the growing season, making sure soil is fairly dried out between waterings. Do not water between November 1 and March 1.
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.
