Most Aeonium species are endemic to the Canary Islands, with a small number found in the Cape Verde Islands, Madeira, Morocco, and eastern Africa. Dry summers and winter rainfall is the norm for their native haunts. Some members of the genus are quite popular as garden and pot plants and have become naturalized in other parts of the world and are now considered weeds. Some species, however, are still quite rare in cultivation. There are also a number of very popular hybrids and cultivars available. In general, they are quite easy to care for, and their very hardiness makes them landscaping favorites in drier climes. The genus shows a wide variety of growth patterns, from the tall, branching A. arboretum to the minute, spreading A. sedifolium. Many species form low, spreading mats such as A. haworthii, while others, like A. nobile, form a single large, if not spectacular, rosette. Some species are monocarpic, dying after they blossom. The plants are propagated by leaf cuttings, stem cuttings, and by seed.
