Aloidendron barberae is an evergreen tree named after Mary Elizabeth Barber, a plant collector in the Transkei. This tree can grow up to 18m with a rounded spreading crown. The main stem sometimes branches from low down. It is the largest Aloe in Africa and is popular for its upright shape which has architectural qualities. This tree’s distribution in South Africa stretches from KwaZulu-Natal in the north to Eastern Cape in the south. The Tree aloe occurs naturally in subtropical coastal forests, kloofs, and dry valleys in the summer rainfall regions.

Aloidendron barberae has large distinctive branches and a rough greyish bark. The bark is furrowed on old branches and smooth on young ones. It bears a rounded crown of long, dark-green succulent leaves that have toothed margins. The leaves are arranged in dense rosettes crowded towards branch ends. Tree Aloe flowers from April to June producing relatively small flowers that vary in colour from orange to pink. These blooms are rich in nectar attracting sunbirds and other insects to the garden.

This Aloe makes an excellent focal point in the garden and grows well in large pots, making it an ideal specimen for garden and parks. Although Aloidendron barberae has a shallow, spreading root system, care should be taken not to plant it too close to buildings because the stem base can grow very big.
