      Aloe barberae, Tree aloe, is native to South Africa. As a slow-growing tree it is up to 18m high and 0.9 m in stem diameter, which is believed Africa's largest aloe. This plant is a striking sculptural tree aloe bearing a rounded and neat crown, forming an excellent focal point in the garden. The branching is forked or dichotomous. The leaves are arranged in a dense rosette, long, narrow, deeply channelled and curved. The leaf surface is dark green with a toothed margin. The inflorescence is produced from the upper axillae. The racemes are cylindrical and its tubular flowers rose pink (green-tipped) and appear in winter. The tree aloe is often used as an ornamental plant.
