Aloe ferox

Aloe ferox, the Cape Aloe, is a single-trunked tree-like species known for its medicinal properties similar to those of Aloe vera. It is a succulent plant that has become rare in its South African homeland, probably due to the excessive harvesting of the gel contained in its large leaves. Its architectural design will delight exotic plant enthusiasts. Although not hardy, this plant withstands long, hot, and dry summers very well. In colder and wetter regions, it can be easily grown in a large pot and overwintered frost-free.

Aloe ferox is a South African botanical species in the Asphodelaceae family, native to an area including the Western Cape, Eastern Cape, Free State, KwaZulu-Natal, and Lesotho. In the wild, it is found in hills, in grassy fynbos (a type of dry savanna), and on the edge of the Karoo desert. This species is listed as an endangered plant. It is a succulent tree-like perennial plant. In the ground, Cape aloe can reach a height of 3m. Young plants form a rosette shape, with the trunk starting to develop after a minimum of 3 or 4 years. The rosette of leaves can reach a diameter of 1m. It consists of thick, green-grey leaves arranged in a spiral. Each leaf can weigh up to 2kg. The edges are equipped with small reddish-brown thorns, as is the underside. The upper surface of the leaves is usually spineless. Flowering occurs on mature plants. It can appear in different seasons, depending on the climate. From the rosette of leaves, a branched flower spike emerges that can measure between 60cm and 1.20m in height. Each branch carries a very dense floral spike composed of numerous small tubular flowers. Each flower consists of 6 petals and long protruding stamens. The colour of the flowers changes successively from coral red to orange and then yellow before fading.

Cape aloe grows very well in a large pot to decorate the terrace or balcony, taking care to bring it indoors frost-free in autumn. It can be overwintered in the house or in the conservatory, in any bright and not too heated room. This plant will also thrive in the ground on protected coasts, in a rock garden or on a well-drained slope. It is hardy to -4/-5°C at most in very dry soil. For example, it can be associated with small agaves or a collection of cacti and succulent plants. You can plant ground covers with the same undemanding temperament, such as Delosperma, which will fill the space around its emerging silhouette.

About Agaves and Aloes:

Aloes and agaves resemble each other but belong to two different botanical families. The main difference lies in the fact that aloe rosettes flower for many years, while the flowering of a mature agave rosette marks the end of its life. In some species of Aloes, interfoliar buds give rise to new plants that cover the dried remains of the mother plant. In agaves, the central flower spike develops from the terminal bud. In aloes, the flower buds emerge between the leaves. Agaves are native to North America, while aloes are found only in the southern half of Africa and in nearby islands in the Indian Ocean.
