Agave americana is a popular succulent that forms large attractive rosettes of grey-green to blue-green leaves. Each rosette grows up to 6 feet (1.8 m) tall and up to 10 feet (3 m) in diameter. Leaves are up to 5 feet (1.5 m) long and have a waxy bloom, pointed tip, and sharp marginal spines. Despite its common name, "Century Plant," it typically lives between 10 and 30 years. Near the end of its life, the rosettes send up a stout flowering stalk, branched near the top and up to 30 feet (9 m) tall. Flowers are yellow or greenish-yellow, up to 4 inches (10 cm) long, and occur in panicles at the branch ends. Rosettes die after flowering but produce offsets around the base, often forming a colony of new plants. Fruits are oblong capsules with a pointed tip, up to 3.2 inches (8 cm) long, and turn from green to brown as they mature.
The specific epithet "americana (a-mer-ih-KAY-na)" means "American" and refers to the place where the species was first discovered. It is a compound of two words, "America" and the feminine form of the Latin suffix "-anus."
How to Grow and Care for Agave americana
Light: Like all Agaves, this plant requires full sun to partial shade. If you are growing A. americana indoors, choose a bright, sunny window with as much sun as possible. From spring to fall, it loves going outside.
Soil: A. americana will tolerate most soils as long as they have good drainage, but its preference is sandy or rocky soil.
Hardiness: During the growing season, it likes warm temperatures, while in winter, when resting, this succulent enjoys cooler temperatures. A. americana can withstand temperatures as low as 10 to 50 °F (-12.2 to 10 °C), USDA hardiness zones 8a to 11b.
Watering: From spring to fall, water thoroughly when the soil becomes dry. In winter, water sparingly about once a month. Plants in containers require more frequent watering than those in the ground.
Fertilizing: Give your A. americana a small amount of fertilizer in the spring during the first two years. Established plants seem to take care of themselves.
Repotting: If you notice your A. americana becoming pot-bound, repot it with fresh soil in a new pot that is just slightly larger than the old one. Give the plant a week or so to readjust before you water it again.
Propagation: Since it can take years to produce seeds, A. americana is usually propagated by offsets. The best time to remove the offsets is in spring and summer. Sow the seeds in spring.
