Agave macroacantha is a succulent that forms dense clumps of rosettes that can be basal or grow on a very short stem. Leaves are fleshy, grayish-green, and up to 1.8 feet (55 cm) long. They have small dark brown teeth and an almost black, up to 1.2 inches (3 cm) long terminal spine. Flowers are small, grey and red, and appear in clusters on a sturdy, up to 10 feet (3 m) tall stem.
USDA hardiness zones 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C).
How to Grow and Care
Agave is not a difficult plant to grow. They are slow-growing and dramatic and will even thrive on a bit of neglect. If you're the type of person who likes to fuss with houseplants and water a lot, Agave is probably not the plant for you. If, however, you're the type of person who likes to set it and forget it, and you have a sunny window, Agave might be the way to go. Be aware that some of the large varieties will eventually outgrow your room (unless you have a large greenhouse), and Agave can be aggressive. They have irritating sap and sometimes very sharp thorns that can cause injuries to small children and even pets.
In general, Agaves do not need to be repotted every year. This is because most species commonly found in cultivation grow very slowly and take a long time to outgrow their pot.
