Aloe rivae, commonly known as Aloe, is native to east Africa including Kenya and Ethiopia. In its native habitat it grows in open wooded grassland on rocky slopes.

The etymological root of the binomial name Aloe is derived from the Semetic alloeh a name for this genus. Rivae is named after Domenico Riva (1856 – 1895), an Italian botanist.

The landscape architect may find Aloe rivae useful as a suitable specimen plant in a rock or desert garden setting. Its is also suitable for growing as a house plant, suitable for bright conditions.

Aloe rivae prefers moist, well-drained soils. It tolerates most pH of soil.

When maintaining Aloe rivae as a houseplant its soil should be watered regularly. Watering should be reduced during the winter months. Its preferred active growing temperature rages from between 18ºc to 28ºc, although it will tolerate a temperature as low as near freezing. Feeding with weak fertiliser solution should be carried out once a month during the growing season. Cuttings may be taken from sprawling plants, placed in moist sand for a couple for weeks, during which period they will root.
