Tree Aloe (Aloe barberae)

Tree Aloe is a large succulent that grows into a tree 30 feet tall or more with upright-growing thick mottled gray 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 in full sun or light shade in a fairly well drained soil and irrigate only occasionally to infrequently. It is moderately drought tolerant in our mediterranean climate and overwatering of heavy soils, particularly in shady locations, seems to promote a black leaf spot. Hardy to about 25 degrees F and reportedly survives short durations down to 22 degrees F.
