Aloe distans

In the genus Aloe, most species grow upright — rosettes pointing skyward, stems reaching for light. The creeping aloes (series Mitriformes) do the opposite: they sprawl. Their stems run along the ground, cascade over rocks, hang from cliffs, and colonize rubble fields — a horizontal growth strategy that is unique among the large-rosette aloes and ideally suited to the rocky, wind-swept Cape mountains where they evolved.

Aloe distans is the smallest, fastest-growing, and most commonly cultivated member of this creeping group. Where its relatives Aloe mitriformis (= Aloe perfoliata subsp. mitriformis) and Aloe comptonii grow slowly and stay compact, distans is an aggressive, rapid colonizer — sending long, sprawling, snake-like stems up to 3 metres across the ground, each stem tipped with a small, jewel-like rosette of bright green leaves armed with prominent golden-yellow teeth. The overall effect is a living cascade of toothed rosettes spilling over rocks and walls — and when the scarlet, capitate (head-shaped) flower clusters appear in late spring to early summer, the display is spectacular.

The species is restricted to a narrow coastal belt around Saldanha Bay in the Western Cape — one of the smallest ranges of any widely cultivated aloe. Despite this tiny native footprint, it is one of the most common aloes in gardens worldwide, propagated from stem cuttings that root with almost absurd ease. Its combination of ornamental appeal, fast growth, ease of propagation, and snow-surviving toughness (Wikipedia: “it easily survives through both very hot summers and snow in the winter”) makes it one of the most reliable ground-cover aloes for Mediterranean and temperate gardens.

Taxonomy: A Name That Will Not Stay Put

Family: Asphodelaceae Subfamily: Asphodeloideae Genus: Aloe Accepted name: Aloe distans Haw. (1812) — recently reinstated as a distinct species by SANBI after long treatment as Aloe mitriformis subsp. distans or Aloe perfoliata var. distans Taxonomic note: POWO currently treats distans as a synonym of Aloe perfoliata L. The BCSS (British Cactus and Succulent Society) treats it as Aloe mitriformis subsp. distans. SANBI’s Red List reinstated it as a separate species. This article follows the SANBI reinstatement. Common names: Jewelled Aloe, Creeping Aloe; Juweel-aalwyn (Afrikaans)

The taxonomic history of Aloe distans is one of the most confusing in the genus Aloe — a species that has been described, synonymized, reinstated, resynonymized, and reinstated again over the past two centuries.

1812 — Original description. Adrian Hardy Haworth described Aloe distans as a distinct species.

2002 — Demotion to subspecies. Van Wyk & Smith reduced distans to a subspecies of Aloe mitriformis: Aloe mitriformis subsp. distans. Under this treatment, the three forms — mitriformis (compact, slow), comptonii (large, eastern), and distans (small, fast, coastal) — were united under one species name.

Later — Further lumping into Aloe perfoliata. Some authorities went further and synonymized the entire mitriformis complex under the older Linnaean name Aloe perfoliata, creating Aloe perfoliata var. distans. POWO follows this treatment.

Recent — SANBI reinstatement. The SANBI Red List notes that Aloe distans “was only recently reinstated after long being considered a synonym of Aloe perfoliata (now Aloe mitriformis).” The reinstatement is based on the species’ restricted coastal distribution, smaller size, prominent marginal teeth, faster growth rate, and more heavily spotted leaves — characters that distinguish it from the interior mountain forms.

Key Diagnostic Characters (vs. Aloe mitriformis sensu stricto)

Paleofish on Agaveville summarizes: “distans is less than half [the] size [of comptonii] and a much greener, faster-growing plant.”

Distribution and Ecology

Native Range

Aloe distans is restricted to a narrow coastal belt in the Western Cape, centred on Saldanha Bay and extending from approximately Danger Point (150 km north of Cape Town) northward to St. Helena Bay (Van Wyk & Smith 2003; BCSS).

This is one of the smallest native ranges of any commonly cultivated aloe — a coastal strip barely 200 km long. The species grows on rocky outcrops and sandy flats near the coast, in the West Coast Strandveld vegetation type — a Mediterranean-climate landscape of low scrub, windswept rocks, and sandy soils, receiving most of its rainfall in winter.

The species is assessed as Vulnerable (SANBI Red List), with “a continuing population decline inferred.” SANBI notes that the species is “locally abundant in suitable habitat” but that only seven subpopulations are currently known. Threats include coastal development, habitat degradation, and the species’ restricted range, which makes it vulnerable to localized events.

Like all Aloe species except Aloe vera, it is listed on CITES Appendix II.

Ecology — Coastal Wind, Winter Rain, and Vegetative Colonization

The coastal habitat is windswept, salt-sprayed, and cool — very different from the montane habitat of Aloe mitriformis proper. The species is adapted to:

Wind. The low, sprawling, ground-hugging growth form minimizes wind resistance. The stems run along the ground or cascade over rocks, keeping the rosettes below the wind shear layer.

Vegetative propagation. Stem fragments that break off root readily on contact with the ground — a colonization strategy perfectly suited to rocky coastal terrain where seed establishment is unreliable. SANBI notes for the broader mitriformis group: “Pieces of the stem that break off also root easily when in contact with the ground.”

Winter rainfall. Unlike the summer-rainfall maculate aloes, distans is a winter-rainfall species — actively growing during the cool, wet Cape winter and resting during the hot, dry summer. The summer-flowering habit (late spring to early summer) is also the opposite of most aloe species.

Morphological Description

Aloe distans is a small, fast-growing, freely branching creeping aloe with sprawling stems up to 3 m long. Stems are slender, prostrate, with erect, leafy terminal rosettes approximately 15 cm in diameter.

Leaves. Short, broad, roughly triangular, bright green (greener than the bluish mitriformis), often with scattered white spots — particularly on young growth. The leaf margins are armed with strong golden-yellow teeth that are the species’ most eye-catching feature. Leaves are retained along the stem, giving the sprawling stems a leafy, snake-like appearance.

Inflorescence and flowers. Flowers are arranged in dense, capitate (head-shaped) racemes — geometrically attractive, almost like fireworks of red. Individual flowers are deep scarlet, approximately 4 cm long (BCSS). Flowering occurs in late spring to early summer — unlike most aloes which flower in winter.

Growth rate. Very fast. Paleofish on Agaveville describes it as “an aggressive, rapid grower” — the fastest of the three mitriformis subspecies. Stem cuttings root and establish quickly.

Cold Hardiness: A Cape Mountain Survivor

Source-by-Source Analysis

Agaveville — Paleofish (mitriformis thread):Aloe mitriformis — pretty cold hardy down to at least 25 °F (–4 °C).” This applies to the mitriformis type; distans, being a coastal rather than montane form, may be slightly less hardy.

Agaveville — Paleofish (comptonii thread): “It seems to be fairly cold tolerant, not showing any obvious damage when we had a frost down to 25 °F.” — This applies to comptonii, the largest subspecies.

Wikipedia (Aloe perfoliata): “A very tough and compact species, it can be grown on embankments, rocky slopes and walls, and it easily survives through both very hot summers and snow in the winter.”

SANBI (PlantZAfrica, Aloe mitriformis): “The plants favour mild to hot summers and easily survive occasional snow in the rainy season.” Also: “The plant in itself is very tough and can often survive for several seasons without water.”

Llifle: “They can resist some cold and occasional snow in the rainy season although the frosts produce wounds and burns that disfigure their aspect.”

The Llifle note is important: frost causes cosmetic damage (wounds and burns) before killing tissue. The plant survives, but it does not emerge unscathed from hard frost.

Agaveville — Arizona grower (updated observations): Lists Aloe distans in the “don’t bother trying” category for Phoenix — but the reason is summer heat, not winter cold. Another Arizona grower notes: “Aloe distans grows at Tohono Chul much to my surprise, but that garden is blessed with alluvial soils above 2,200 feet.” — At higher elevation with cooler summers, the species succeeds.

Ecological Inference

The Saldanha Bay coastal climate is mild: winter lows rarely drop below –2 to –3 °C, and snow is exceedingly rare at sea level. However, the montane populations of the broader mitriformis complex (1,200 to 1,500 m altitude) experience regular frost and occasional snow — confirming the group’s inherent cold tolerance. The key distinction for distans is that it comes from the mildest part of the complex’s range (coastal, low altitude), which may translate to slightly lower frost tolerance than the montane forms.

Practical Synthesis

USDA zones 9a to 11b.

  • Zone 10a–11b: Reliable, excellent ground cover.
  • Zone 9b: Very good. The 25 °F (–4 °C) rating from Agaveville and the snow-survival reports provide strong confidence. Expect cosmetic frost damage on leaf tips in cold years, but no mortality.
  • Zone 9a (dry-winter): Viable for established plants. The prostrate, ground-hugging growth form provides natural frost protection (cold air flows over rather than through the plant). Cosmetic damage likely.
  • Zone 9a (wet-winter): Marginal. The winter-rainfall origin suggests tolerance of wet cold, but hard frost (below –6 °C) combined with wet soil may cause rot.
  • Zone 8b: Not recommended for permanent outdoor planting without protection.

Comparison with Two Related Species

Aloe distans vs. Aloe mitriformis Mill. (Rubble Aloe / Mitre Aloe)

The coastal form vs. the montane type:

CharacterAloe distansAloe mitriformis
DistributionCoastal (Saldanha Bay)Montane (1,200–1,500 m)
Rosette size~15 cm (smaller)15–30 cm (larger)
Growth rateVery fastSlow
Leaf colourBright green, spottedBluish-green, usually unspotted
TeethProminent, golden-yellowSmaller, variable
StemsLong (up to 3 m), heavily leafedShorter, less leafy
Cold hardiness25 °F (probably)25 °F (Agaveville)

Distans is the faster, greener, smaller, more ornamental form for ground-cover use; mitriformis is the slower, bluer, more compact form for rock-garden focal points.

Aloe distans vs. Aloiampelos ciliaris (Haw.) Klopper & Gideon F.Sm. (Climbing Aloe)

Two sprawling aloes with very different strategies:

CharacterAloe distansAloiampelos ciliaris
Growth habitProstrate, ground-huggingClimbing, scrambling
Stem lengthUp to 3 m (horizontal)Up to 5 m (vertical/scrambling)
Leaf shapeShort, broad, triangularNarrow, elongate
FlowersCapitate (head-shaped)Cylindrical racemes
Flowering seasonSummerWinter
Cold hardiness~25 °F~25 °F (similar)

Distans covers the ground; ciliaris climbs through shrubs and over walls. Both are excellent for erosion control and informal cascading plantings.

Optimal Growing Conditions

Light

Full sun for best leaf colour, densest growth, and maximum flowering. Tolerates partial shade but becomes etiolated and less colourful.

Temperature

Mild coastal preference. Tolerates frost (to at least –4 °C) and summer heat — but extreme desert heat (Phoenix-type, >45 °C with low humidity) is poorly tolerated (Arizona “don’t bother” reports). Best in Mediterranean or mild-maritime climates.

Substrate

Well-drained, sandy to rocky. The natural habitat is coastal sand and rock. Standard succulent mix works well.

Watering

Winter-rainfall pattern: water in winter (the active growth season), reduce or stop in summer. Drought-tolerant once established — SANBI notes survival “for several seasons without water.”

Landscape Uses

Ground cover, wall cascading, rock garden, erosion control, embankment planting, hanging baskets, coastal gardens. The sprawling habit and fast growth make this one of the best aloes for covering large areas quickly. The golden-toothed leaves are ornamental year-round, and the scarlet summer flowers are a bonus.

Hardiness Zone

USDA zones 9a to 11b.

Propagation

Stem cuttings are the easiest and fastest method — the stems root readily. Allow cut sections to callus before planting.

Division of established clumps.

Seed germinates readily but stem cuttings are far faster.

Pests and Diseases

Scale, aphids, and aloe snout beetle. Root rot from overwatering in summer (the dormant season). In Arizona, summer heat stress is a greater threat than any pest.

Conservation

Aloe distans is assessed as Vulnerable (SANBI Red List). Only seven known subpopulations exist in its restricted coastal range. While “locally abundant in suitable habitat,” the species’ dependence on a narrow coastal strip makes it vulnerable to development and habitat loss. Cultivation from ethically sourced material (nursery-propagated cuttings, not wild-collected) is the responsible approach.
