Aloe maculata All.
Soap Aloe / Spotted Aloe
Soap Aloe is one of the most widely distributed Aloe species in southern Africa, naturalised across many Mediterranean and Macaronesian countries. Its common name derives from the fact that its leaf gel lathers like soap when rubbed between the hands, a property traditionally used to wash clothes and hair.

Overview
| Category | Classification |
|---|---|
| Family | Asphodelaceae |
| Genus | Aloe |
| Growth Habit | Acaulescent to subcaulescent; forms dense colonies through basal offsets. |

| pH Target | 6.0 – 8.0 |

Origin & Habitat
Morphology
Lanceolate-triangular leaves 20–35 cm, bright green with irregular white spots (from which the epithet maculata derives), most evident on young plants; margins with cream to brown spines of moderate strength.
ecoStem very short, rarely visible; in dense colonies basal shoots overlap to form compact rosette masses up to 1 m across.
ecoSimple inflorescence 60–100 cm; cylindrical raceme with bicoloured flowers — red at the base and yellow at the tip — or entirely yellow or red depending on variety. Blooms autumn–winter (Southern Hemisphere: May–July).
ecoFibrous shallow root system with short rhizomes that facilitate clonal spread. Highly efficient in dry poor soils.

Propagation Strategy
- 1 A. maculata propagates actively through basal offsets and underground stolons that produce new plants away from the mother (as in nature)
- 2 For direct offsets: separate when they are 8–10 cm tall with their own roots using a disinfected knife
- 3 For stolon plants: locate the underground connection point and cut it cleanly; the new plant already has its own roots
- 4 Plant immediately in well-drained substrate; water after 7–10 days
- 1 Sow fresh seeds on the surface of fine sand + perlite; do not cover
- 2 Keep at 20–25 °C under a transparent cover; lightly moisten every 3–4 days
- 3 Germinate in 2–3 weeks; gradually ventilate before removing the cover
- 4 Transplant to individual pots when seedlings are 3–4 cm
A. maculata is one of the easiest species to propagate; stolons make it an excellent ground cover in dry gardens
Not controlling stolons in small spaces, where they invade other plants
Every 1–2 years in spring, given its rapid stolon growth; or when roots emerge from the pot.
Succulent fertilizer at 50% dose, once in spring and once in summer; no fertilizer in autumn or winter.
Uses & Applications
Precautions / Toxicity
Low human toxicity. Latex (aloin) is mildly toxic to dogs and cats. CITES Appendix II.

"A. maculata is one of the few Aloe species producing a soap-like lather due to saponins in its gel — a convergent trait with Saponaria officinalis reflecting independent adaptation. Its ease of naturalisation makes it invasive in Portugal, the Canary Islands and parts of Australia."
