Aloe rupestris, commonly known as the Bottlebrush Aloe, is a fast-growing, single-stemmed succulent native to rocky outcrops and bushveld in southeastern South Africa, Eswatini, and southern Mozambique. It can reach up to 33 feet in height, though it often requires support to prevent falling over. The Bottlebrush Aloe is notable for its tall candelabra inflorescences with densely packed yellow buds that open to reveal bright reddish stamens, resembling a bottlebrush. This occurs during the winter months, adding vibrant color to the garden when few other plants are in bloom. The leaves are U-shaped, deeply grooved, with reddish-brown margins and slightly hooked teeth, which add to its distinctive appearance.

In cultivation, Aloe rupestris is valued for its dramatic floral display and architectural form. It is well-suited to rockeries, succulent gardens, and as a focal point in xeriscaped areas. This aloe prefers full sun to partial shade, well-draining soil, and requires minimal water once established, making it a low-maintenance choice for dry climates. It is also used in traditional medicine. However, it is important to provide ample space for growth and to be cautious of the sharp teeth along the leaf margins. While generally disease-resistant, it can be susceptible to root rot if overwatered.CC BY-SA 4.0
