Astroloba corrugata is widespread and well-defined species, it is immediately recognisable by its stout (often recurved) leaves which are covered in tiny, fine, asperous tubercles. Like all Astrolobas, its stems branch & offset from the base, forming columns that are densely covered in sharp, succulent leaves. It grows very often with Haworthia arachnoidea var. nigricans and Gasteria brachyphylla.
These plants are increasingly popular as succulent ornamentals, due to the extraordinary beauty of their leaf structure. Some have intricate patterns of lines, margins, spots and raised tubercles on their leaves. Nearly all of them display a crystal-like regularity in their leaf arrangement. This is not always apparent in wild plants, which are usually disfigured by their harsh habitat. In cultivation, they are at their best when provided with some protection from full sun. In a semi-shade environment, with extremely well-drained soil and gentle conditions, Astrolobas can become remarkably beautiful and ornate. Unfortunately, when conditions are not ideal, occasional random leaves can die, shrivel up and go brown, all along its stem. This is unfortunate because, as explained, much of the beauty of the plants comes from the intricate, crystalline pattern of their leaves. However this disfigurement can be avoided by keeping the plants in optimal, fertile conditions – growing steadily and sheltered from stress.
All Astrolobas can be propagated by seed, by cuttings/offsets, and by division of clumps. Cuttings or offsets should be dried for several days to weeks, in a cool, shady environment, before being planted in well-drained sand. Seeds should be collected and sown on well-drained soil. It is optional to cover them with a very thin, fine layer of sand. Keep moist until they germinate, and continue to water regularly until they are relatively large and strong. Keep in a bright spot, but out of direct sunlight. Hybrids can be made between all the Astroloba species (except for rubriflora, which has evolved a highly distinct chemistry in its flowers). Astrolobas can also be hybridised with other related genera, such as Tulista, Haworthiopsis, Gasteria, Aristaloe, Gonialoe and Aloe themselves. It is especially easy to hybridise with Gasteria and Tulista.
