Cultivation and Propagation: Agave avellanidens is usually cultivated outdoors in rock gardens, in cactus and succulent gardens, in Mediterranean-style landscapes, in borders, or as a specimen. It needs full sun and a very well-drained, slightly acidic, sandy or gravely soil. As an ornamental it is also grown in containers where it stays much smaller than its outdoor brethren. Keep it in a cool, frost-free area in winter and put it out on the balcony or patio in summer. It grows fairly fast in summer if provided with copious water but allows to dry thoroughly before watering again. During the winter months, one should only water enough to keep the leaves from shrivelling. It do well in full sun or a lightly shaded area.
Scenography: These striking plants are wonderful when used for accent or simply to provide some all year round foliage and often used in a pot as a patio plant, can be moved around to change the scenery or position to give more shelter.
Warning: It can get large, and it is armed with needle-sharp spines.
Propagation: Seeds or suckers which often are found growing around the base of the plant. Remove the basal suckers (if available) in spring or summer and let the cuttings dry for a few days before inserting in compost.
