Leaves: Short, unusually thick, wavy blue-green highlighted by 5 cm wide golden borders. The leaf margins tend to be somewhat irregular and irregularly spined as well.

Cultivation and Propagation: These striking small agaves 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.
Cultivation: 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 americana is theoretically hardy to -9° C, particularly when dry but this cultivar is more tender and it is best to avoid 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.
