Description: Caralluma caudataSN|16423]]SN|16423]] (now transferred to Orbea caudataSN|16424]]SN|16424]] by Bruyns or to Orbeopsis caudataSN|16425]]SN|16425]] by L.C.Leach) has five-pointed fleshy starry flowers produced in late Summer or Autumn. The blooms are delicate and beautiful but exude an intense smell of rotting meat. This perfume attracts blow flies which are the natural pollinators.
Habit: It is a low clumping perennial succulent species that spread over the ground forming lax cushions. Plant to 9 cm tall and up to 20 cm in diameter.
Stems: 8-10 cm long 7-10 mm across, excluding teeth. Teeth long-tapering, spine-like, more or less spaced, horizontally spreading or up-curved 9-10 mm long and 5-8 mm broad at the base. Epidermis brownish-green or dark olive-green or grey-green more or less mottled with brownish or purple.
Flowers: Usually solitary or few together in pseudo-umbels near base of stem, rarely more than 2 open at once. Flowering stalks, erect, 5-20 mm long 2-3 mm large. Flowers buds up to 3,8 cm long 5-angled terminating in a slight spiral. Bracts 2,5 mm stiff. Corolla 4-9 cm in diameter, very deep-cleft, basin-shaped at the base, lobes up to 22 mm long, outside whitish stippled with red, inside not wrinkled variably downy or papillose, yellowish to dark-yellow with reddish or violet spots (rarely completely dark purple). Lobes lanceolate-acuminate to caudate, 22-40 cm long, 6-9 mm wide, horizontally spreading, border ciliate below, recurred above. Hairs purple to violet vibratile. Corona yellowish-red 4-7 mm in diameter, often entirely within the central purple depression. Outer corona-lobes 1,5 mm long, inner corona-lobes simple, lying over anthers, without extended horn. Pollinia 0,5 mm long 0,35 mm wide, bean- or D-shaped
Blooming season: This species produces few flowers simultaneously in late summer to autumn. Following successful pollination of flowers pairs of seed horns are produced, packed with seeds attached to silky parachutes.

Cultivation and Propagation: Caralluma caudataSN|16423]]SN|16423]] is a xerophytic plant adapted to dry soils, but despite its provenance it is without doubt an easy species to grow and not difficult as commonly supposed only bearing in mind that this species benefits from slightly warmer winter than others.
Growth rate: It is a relatively rapidly growing and easily flowering species that will make large clumps given the best conditions. Most plants will offset readily, and clumps can be produced in a few years.
Soils: It likes very porous mineral cactus mix soil, pH 7,5 to 8,5 (mildly alkaline), but can become too elongated if compost is too rich.
Repotting: This plant needs plenty of space for its roots, repotting should be done every other year or when the it has outgrown its pot. Use pot with good drainage.
Watering: It needs regular watering, especially during the hottest summer days; provide also some light watering if the green house temperatures in winter are elevated. Either excessive or very scarce watering can induce rot.
Fertilization: Feed with a high potassium fertilizer in summer.
Frost Tolerance: For safe cultivation it is best to avoid freezing temperatures (minimum 5° C). In the rest period no high atmospheric humidity!!
Sun Exposure: Best for half-shade but grow well in full sun and full shade too. Tends to bronze in strong light, which encourages flowering, but is likely to suffer from sun scorch or stunted growth if over exposed to direct sunlight during the hottest part of the day in summer.
Diseases: This species is relatively resistant to cryptogamic diseases than others and is quite resistant to the “Balck spot” disease of Asclepiads. Rot it is only a minor problem with Caralluma caudataSN|16423]]SN|16423]] if the plants are watered and “aired” correctly. If they are not, fungicides won't help all that much.
Uses: It is an excellent plant for container growing. Cascading, clustering, great for a hanging display. Stems may possibly become purple and limp in winter, but revitalize in early spring. It always looks good and stays small. It look fine in a cold greenhouse and frame or outdoor in a rockery.
Propagation: Seeds and cuttings. Cuttings will root only in hot weather. Cuttings must be kept very dry to root. Seeds germinate readily if they are sown when fresh.
