Aloe hemmingii is an attractive succulent that forms rosettes of shiny, lime green to dark green or orange leaves with numerous white linear spots. The rosettes have 10 to 15 leaves and grow up to 10 inches (25 cm) in diameter. Flowers are yellow to reddish and appear in spring on an unbranched or few-branched inflorescence. This species is very similar to Aloe somaliensis and often erroneously sold as Aloe harlana by many nurseries and garden centers.
Do not allow the plant to sit in water. Allow the soil to dry through completely before watering again.
It wants high light. As much direct light as possible should be provided, a south or west facing window (in the northern hemisphere) would be ideal. When placing this plant in direct sunlight it should be slowly acclimated over a few days to avoid the risk of leaves scorching or yellowing.
Aloe does not require a high soil fertility. Feeding once a year, in the spring, with a houseplant fertilizer should be sufficient.
Use an extremely well draining soil mix (see succulent soil) and water thoroughly, allowing excess to drain.
Plant will survive temperatures down to 5°C / 41°F. Daytime temperatures between 15°C and 26°C (60°F and 80°F), and night temperatures between 12°C and 21°C (55°F and 70°F) are ideal for healthy growth.
