Aloidendron is a genus of succulent plants in the subfamily Asphodeloideae. It was split off from the much larger genus Aloe in 2013. Although aloes are most often included in rockeries, their application in horticulture is not limited to this feature and they can be used in almost any setting and in conjunction with most common garden plants. Their natural adaptation to harsh and often arid climates makes aloes outstanding subjects for the water wise garden.

Aloidendron barberae, previously known as Aloe barberae and also Aloe bainesii, is commonly known as Tree Aloe. It is a large succulent that grows into a tree up to 15 meters tall with upright growing thick mottled grey stems. The terminal branches hold rosettes of recurved, dark green leaves. In late winter, the rose-pink flowers in a tight inflorescence rise above the foliage. Plant Aloidendron barberae in full sun for best results. They are drought tolerant and hardy to about -4°C although reportedly survives short durations down to -7°C. It is a great tree for the succulent garden or near a pool and is good in large containers but should be fertilized regularly.
