Description: Solitary or slowly clumping succulent rosette that will grow to a height of 90-120 (150). The arching leaves are characteristically variegated and have a broad creamy white band down the centre of each leaf, with grey-blue sharp-spined edges.

Cultivation and Propagation: This is a very popular cultivar but it is relatively slow to grow and propagate, it tend to do less well than the standard blue-grey species plant, hence the price. They do well in full sun or a lightly shaded area.
In winter watering this plant can be done once every 1-2 months, there is no need to mist the leaves. Agave americanaSN|162]]SN|162]] is theoretically hardy to -9° C , particularly when dry but this cultivar is more tender and it is best to avoid severe freezing temperatures.

Propagation: Exclusively by suckers Remove the basal suckers (if available) in spring or summer and let the cuttings dry for a few days before inserting in compost.

Use:: These striking plants are wonderful when used for accent or simply to provide some all year round foliage colour and often used in a pot as a patio plant, they make an eye-catching statement and along with other evergreen plants in pots, can be moved around to change the scenery or position to give more shelter.
