Description: Agave attenuataSN|277]]SN|277]] produce smooth curving trunks, often branched and eventually old leaves fall off, leaving them naked and visible. If planted in the ground it will likely form a clump to 90 to 120 cm or more tall by even wider with many rosettes of leaves.(unusual among agaves). Fear not this plant as it has no spines unlike its prickly cousin.
Stems: Stout curving , often branched, smooth grey stems that rise up to 100 cm tall (unusual among agaves) and eventually old leaves fall off, leaving them naked and visible.
Leaves: Wide, soft, pliable, somewhat translucent ovate-accuminate, 50-70 cm long and 12-16 cm large. The leaves are powdery green, light yellowish green or grey/blue green.There are no teeth, nor terminal spines, although the leaves taper to points that fray with age. They emerge from a tight central spear to arch gracefully back, looking a bit like a large open green flower.
Flowers: Flowers are pale greenish yellow on a dense raceme 1,5-3,5 long . Over many months the vertical flower stalk develops, first as a mass of green buds which open from the bottom up into flowers of greenish-yellow, then it reflexes back towards the ground before arching upward again. The flowers are followed by seed pods and from the axils of the flowers many new 'plantlets' (or bulbils) will sprout, meanwhile the mother rosette slowly dies. But sometime - unlike other members of it's family - this plant doesn't die after flowering.
Blooming Time: Spring. It may take up to 10 years to bloom.
Cultivation and Propagation: Agave attenuata is an excellent plant which works well with other succulents or even tropical plant material. It is well suited for a container inside or a sheltered warm spot outdoors. It is a frost tender plant and it will usually be severely damaged in temperatures below -2° C. Although Agave attenuataSN|277]]SN|277]] survives in poor soils and can tollerate full coastal sun to to full shade, it does best in rich but well-drained soil mix ( 2 parts peat moss to 1 part loam to 1 part of pumice) with half sun exposures. The plant is extremely drought tolerant but does better with ample moisture and grows quickly if kept well watered and nourished (Slow release fertilizer applied once or twice a year is usually sufficient). During the winter months, one should only water enough to keep the leaves from shrivelling. Plants cultivated outdoors are more drought tolerant and can take some heat and full sun. It tolerates seaside conditions too. Protect from snails which can also disfigure the plant.
Offsets or 'pups' can be removed to maintain the strong architectural lines of the agave and provide great additional plants, or left to form a clump.
Propagation: By seeds or by removing suckers produced at the base of older plants or using the thousands of small bulbils produced on its' entire flower stalk length. Seeds germinate readily when they are fresh. The basal suckers can be removed in spring or summer, letting the cuttings dry for a few days before inserting in compost.
