Botanical Profile

Growing Giant Tree Aloe

This slow-growing tree forms a massive, gray-brown trunk up to 3 feet thick, branching into a rounded crown of rosettes. The leaves are long, curved, channeled, with small teeth. In winter/spring, it produces branched spikes of tubular, rose-pink flowers. It requires full sun, extremely well-drained soil, and minimal water—extremely drought-tolerant.

Hardy to about 25°F (-4°C); zones 9–11. In marginal areas, protect from wet cold. A magnificent specimen for xeriscapes, rock gardens, and large succulent collections. Its architectural form is unparalleled. A living sculpture for frost-free, arid landscapes.
