Aloe barberae, commonly known as the Tree Aloe or the Bitter Aloe, is a large succulent tree native to South Africa. It belongs to the family Asphodelaceae and is known for its striking appearance and unique growth habit.
Aloe barberae is a slow-growing tree that can reach heights of up to 50 feet (15 meters) or more in its native habitat, although it usually remains smaller when grown as a landscape plant. It has a single, thick, grayish-brown trunk that can reach several feet in diameter, topped with a canopy of dense, rosette-like clusters of leaves. The leaves are thick and fleshy, with a blue-green color and serrated edges, and can reach lengths of up to 3 feet (90 cm) or more. In the summer months, Aloe barberae can produce large, showy, tubular flowers that are typically orange or red in color and attract pollinators such as birds and bees.
