Aloiampelos ciliaris
| Light | Bright light to full sun; tolerates part shade |
|---|---|
| Water | Regular in growth; let the top of the mix dry between waterings, drier in winter |
| Soil | Well-draining but slightly richer than most succulents (see Soil and potting mix) |
| Temperature | Keep above freezing; USDA zones 9b–11 |
| Propagation | Cuttings (very easy); also seed |
| Toxicity | Poorly documented for this species; like other aloes it may cause mild digestive upset if eaten, so best kept away from pets. No serious poisonings reported |
Aloiampelos ciliaris is the common climbing aloe, a fast-growing scrambling succulent from South Africa's Eastern Cape. Unlike the stout rosette aloes most growers picture, it produces long, slender, flexible stems that clamber up through surrounding shrubs, edged with soft white marginal hairs and topped, for much of the year, by cheerful clusters of orange-red flowers. It is one of the easiest members of the genus Aloiampelos to grow and root, which has made it a familiar garden and windowsill plant well beyond its native range.
Description
Aloiampelos ciliaris is a climbing or sprawling perennial with thin, cane-like stems that can reach several metres in length when supported, though they remain quite slim — often no thicker than a pencil. The leaves are lance-shaped, soft and slightly recurved, and spaced out along the stem rather than packed into a tight rosette.
The species takes its name from the delicate white hairs (cilia) that fringe the leaf margins and, most distinctively, encircle the stem in a small collar (the leaf sheath) where each leaf clasps it. This ciliate sheath is a reliable field mark separating it from close relatives.
Flowering is generous and can occur through much of the year in mild climates, peaking in late winter and spring. The tubular flowers are carried in loose, unbranched heads and are typically orange-red tipped with green or yellow, attractive to sunbirds and other nectar feeders.
Distribution and habitat
The climbing aloe is native to the Eastern Cape of South Africa, where it grows in thorny, succulent-rich thicket and scrubby bushland, often in dry river valleys near the coast. Its scrambling habit is an adaptation to this setting: rather than building a self-supporting trunk, it leans on and grows up through neighbouring shrubs to reach light, its slender stems threading among the branches of denser vegetation.
Cultivation
Aloiampelos ciliaris is one of the most forgiving of all aloes and an excellent beginner's plant. It appreciates a slightly more generous, water-retentive mix than the stone-loving desert cacti — good drainage still matters, but it will not sulk in an ordinary well-draining succulent soil. Give it bright light to a few hours of direct sun; in too much shade the stems stretch and the plant flowers less.
Because it is a climber, it does best with something to lean on — a small trellis, an obelisk, or an adjacent shrub — though it will also trail attractively from a hanging pot or tumble over a wall. Water regularly through the warm growing season, letting the surface dry between drinks, and ease off in winter. It is fast, hungry by aloe standards, and responds well to occasional feeding and a fresh pot when it fills its container; see Watering and Repotting for general technique. Growth is quick enough that a leggy plant can simply be cut back hard and will resprout.
Propagation
This is where the climbing aloe truly shines: it roots from stem cuttings almost embarrassingly easily. A length of stem laid or stood in a gritty mix, or even in water, will usually root within a few weeks. Take cuttings in the warm season, let the cut surface dry for a day or two, then pot up. The species also grows readily from seed where flowers have been pollinated, but cuttings are so quick and reliable that most growers rarely bother.
Common problems
- Etiolation — the commonest complaint; in low light the stems stretch, the leaves space out further, and flowering drops off. Move it brighter and cut back leggy growth.
- Rot — although more tolerant of moisture than desert succulents, it can still rot at the base if left cold and wet in winter or grown in a poorly draining mix.
- Pests — mealybugs may hide in the leaf sheaths and among the marginal hairs; scale can appear on the stems. See Pests and diseases.
