Field notes
Morphology
Grows to about 60 cm, with thin, winding, upright or hanging stems and flat rosettes 6–11 cm across. The obovate, blue-green leaves are 3–5.5 cm long with fine curved hairs on the margin, which is often tinged red. Loose panicles of pointed cream flowers appear in spring.
Distribution & habitat
Native to the Canary Islands and northern Africa, where it grows as a sand-dwelling coastal plant; introduced to similar climates such as southern California.
Cultivation notes
Grown outside in USDA zones 9–11; drought tolerant and best in full sun. Aphids and mealybugs can be a problem. Wikipedia records an RHS Award of Garden Merit for the species and its 'Variegatum' form, but the species' award was rescinded after the RHS aeonium trial.
