Aloe marlothii (Mountain Aloe)

Aloe marlothii (Mountain Aloe) brings bold structure to xeriscapes and drought-tolerant gardens. This single-stemmed succulent forms a dense rosette of fleshy grey-green leaves with reddish-brown spines along the margins and often across the leaf surfaces. Mature leaves can reach up to 5 feet long, creating a dramatic architectural focal point.

As Mountain Aloe matures, it develops a tall trunk surrounded by a skirt of persistent dried leaves. In winter, mature plants produce branched, candelabra-like flower stalks with horizontal or slightly angled spikes of orange, red, or yellow tubular flowers that attract hummingbirds and bees.

Origin and habitat

Native to South Africa, including KwaZulu-Natal, Mpumalanga, Limpopo, and Gauteng, with its range extending into Eswatini, Botswana, and Mozambique. Aloe marlothii grows in rocky hills, open flatlands, and bushveld.

Mountain Aloe care

• Light: Full sun supports its blue-grey coloration and robust spines. It tolerates partial shade but may grow less compactly.
• Water: Drought-tolerant once established. Water deeply but infrequently, letting the soil dry completely between waterings. Reduce watering significantly in winter to help prevent root rot.
• Soil: Use porous, well-draining cactus and succulent soil. Pumice or coarse sand can help improve drainage.
• Cold protection: Listed cold tolerance is approximately 20°F (-6°C). Protect during hard freezes rather than relying on this temperature as a guarantee.
• Companion plants: Pair with Agave, Portulacaria afra, or flowering Echinopsis for contrasting textures and seasonal color.
