Aloe greatheadii var. davyana is stemless and grows singularly or in groups of up to 15 plants. The succulent leaves are arranged in a basal rosette. The leaves range from triangular to lance-shaped, are often faintly striped above with oblong white spots arranged in more or less distinct bands but are unspotted below and usually a whitish green; margins are armed with sharp, dark brown teeth. In winter, the apical half of the leaf dies back and becomes twisted, leaving the remaining part almost square in shape. The inflorescence can reach a height of up to 1.5 m high and has up to 6 branches. More than one inflorescence is often formed and up to seven have been counted on one plant alone. The flower colour ranges from pale pink to red. The species flowers in midwinter from June to July.
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.
