Aloidendron barberae is a species of aloe native to South Africa northwards to Mozambique. It was previously known as Aloe barberae. It is Africa's largest aloe. The native habitats of this tree are the subtropical coastal forests, ravines and dry valleys in the eastern regions of southern Africa. It is slow-growing can reach a height of 18 m and 0.9 m in stem diameter.
The plant’s branching is forked or dichotomous (the axis is divided into two branches). The branches form a spreading, rounded crown that can be up to 5m wide. The leaves are arranged in a dense rosette, they are long, narrow, deeply channelled and curved. The leaf surface is dark green and has whitish teeth on the margins. In winter it produces tubular flowers which are a coral pink colour and they are borne on small, upright racemes. 

In suitable climates, Aloidendron barberae is planted worldwide as a sculptural focal point in gardens. Because they develop a massive stem base, it is not recommended to plant this tree too close to permanent structures, pools or paving.
