Aloe marlothii

Mountain aloe

A large, single-stemmed tree aloe of the summer-rainfall bushveld of north-eastern South Africa, Eswatini, eastern Botswana and southern Mozambique, reaching 4–6 m with a skirt of dead leaves and spiny grey-green leaves up to about 1.5 m long. Its flat-topped, horizontally branched flower heads of yellow to red flowers appear in the dry winter. It needs full sun, a warm wet summer and a dry, cool winter; indoors only young plants are manageable.

Where it grows wild

On rocky hills, ridges and stony or sandy flats in savanna and bushveld, often on bare stony soils where it can be the dominant plant. It grows fully exposed to sun and wind.

Reported from about 15 m near the coast (subsp. orientalis) to about 1,800 m inland; Flora Zambesiaca gives 1,000–1,200 m for its part of the range. Few wild records carry an elevation.
