Aloidendron barberae, formerly Aloe barberae, also known as the tree aloe, is a species of succulent plant native to South Africa northwards to Mozambique. In its native climes this slow-growing tree can reach up to 18 m (54 ft) high and 0.9 m (3 ft) in stem diameter. Aloidendron barberae is Africa's largest aloe-like plant. The tree aloe is often used as an ornamental plant. Its tubular flowers are rose pink (green-tipped); it flowers in winter and in its natural environment is pollinated by sunbirds.
Aloidendron barberae was first collected and submitted for classification by Mary Elizabeth Barber, who was a plant collector in the former Transkei. She sent specimens of the plant and its flowers to the Royal Botanic Gardens at Kew, where in 1874 it was named by William Turner Thiselton-Dyer (1843–1928) in her honor. Subsequently, it was also found in KwaZulu-Natal by the well known traveller, explorer and painter Thomas Baines in 1873. He also sent a specimen to Kew, where it was named Aloe bainesii. Although known as A. bainseii for many years, Aloe barberae was the name first given to this plant, and takes precedence according to the International Code of Botanical Nomenclature, and so is the epithet used in the combination Aloidendron barberae.
The tree aloe's habitat is subtropical coastal forests, kloofs (ravines) and dry valleys in the eastern regions of southern Africa. Aloidendron barberae is widely distributed from the Eastern Cape through the former Transkei, KwaZulu-Natal, Swaziland and Mpumalanga; and northwards to Mozambique and East Africa.
