Description

Orbea ciliata is a much-branched succulent with decumbent or ascending stems and attractive star-shaped flowers. It grows up to 4 inches (10 cm) tall. Stems are grayish-green to dark purple-brown in full sun, 4-angled, sharp-toothed, and up to 3 inches (7.5 cm) long. Flowers are up to 4 inches (10 cm) across, pale yellow to creamy-white, and dotted with red.

Hardiness

USDA hardiness zone 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C).

How to Grow and Care

Several species are fairly easy to grow. Others, often those with slightly hairy stems and the more unusual flowers, are more challenging and require careful watering (with some fertilizer) during the growing season and complete withdrawal of water during the winter months. A minimum winter temperature of 10°C (50°F) is acceptable, providing that plants are kept dry. A heated growing bench or incubator may help delicate plants to get through the colder months. However, many species live under shrubs in habitat and prefer light shade rather than full sun.

A gritty compost is essential, and clay pots are advisable for the more delicate species. Some growers prefer a mineral-only compost to minimize the chance of a fungal attack on the roots.

Keeping Stapelias and their roots free of pests such as mealybugs is the real key to success as fungal attack often occurs due to damage to stems by insects. See more at How to Grow and Care for Stapelia.

Origin

Native to South Africa (Cape Province).

Kirkia 10(1): 291 1975

Origin and Habitat: It is native to the Karroo Desert in South Africa. (Calvinia Div Hantam, Ceres Div. Karoo between the Roggeveld Mountains and Paarde Berg Karoo between Bokkeveld and Paarde Berg Beaufort West Div. Nieuwveld, between Rhenoster Kop and Ganzefontein Prince Albert Div.

Description: Orbea ciliata is one of the oldest known “stapelia” easily recogizable for the creamy-white flowers with a prominent fleshy cup or raised annulus which forms part of the corolla and for the clavate and strongly vibratile hairs which form a fringe along the edge of the corolla lobes. These hairs hardly remain still and move in the slightest breeze, possibly attracting insects. It is a prostrate-growing plant with branches rooting at the base,
Stems: Short, decumbent and ascending, and branching from the base 4-7 cm long, 12-18 mm thick, exclusive of the teeth, obtusely 4-angled, glabrous, greyish-green, mottled with purple Teeth conical acute, divergent, 4-8 mm long. In cultivation stem tips often become funnel-shaped (cristate) with cup-shaped depressions. In a good light the stems become attractively dark purple-brown.
Flowers: Sub-solitary, up to about 7-10 cm across, bowl-shaped from near the base or middle of the stems with hardly any trace of the carrion odour characteristic of stapeliads. Pedicels 10-12 mm long, erect, glabrous. Sepals about 6-8 mm long 2-4 mm wide, convex ovate or ovate-lanceolate, acute, glabrous. Corolla about 7,5 cm in diameter, pale-green stripped with reddish, smooth and glabrous outside, densely papillate-rugose on the innerface, greyish to pale yellowish, minutely dotted with red, raised at the mouth around the thick recurved rim of the inner tube, which is densely covered with stiff purple hairs at the base around and under the corona. Corolla lobes about 2,5 cm long, 2 sm broad, spreading, ovate, acute, more or less revolute, ciliate from base to apex with clavate strongly vibratile white hairs. Outer corona-lobes arising above the base of the staminal column, connate at the base, somewhat spreading, with the free part 2 mm long, transverse or subquadrate, very obtusely or subacutely bifid, glabrous, apparently yellowish dotted with purple-brown. Inner corona-lobes lying against the backs of the anthers, about 1,5 mm long, thick, ovate, acute, or acuminate with the tips produced into a very short erect point, apparently yellowish, dotted and marked with purple-brown without extended horns or wings.

The gallery now contains thousands of pictures, however it is possible to do even more. We are, of course, seeking photos of species not yet shown in the gallery but not only that, we are also looking for better pictures than those already present. Read More.

Cultivation and Propagation: Orbea ciliata is one of the easiest stapeliads to grow. It like a half-sun or shaded position (never grow in too harsh sun), very resistant to heat will also tolerate quite cold temperatures but avoid frost, best in a ventilated environment. It is quite resistant to the “Balck spot” disease of Asclepiads, Water regularly during the growing season, keep dry in winter. Use a gritty, well-drained soil.
Propagation: It is easily propagated by removing a cutting, sometimes with roots attached, in spring and summer, but seeds germinate readily if they are sown when fresh.
