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 rosette sends 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. The rosette dies after flowering, but produces offsets around the base, often forming a colony of new plants. The 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," means "of America," and refers to its American origin.
How to Grow and Care
Light: These plants require full sun to part shade. If you are growing Agaves indoors, choose a bright, sunny window with as much sun possible. Agave plants love going outside from spring to fall.
Soil: Agaves will tolerate most soils as long as they have good drainage, but their preference is sandy or rocky soil.
Hardiness: Agave americana can tolerate temperatures as low as 10 to 50 °F (-12.2 to 10 °C), USDA hardiness zones 8a to 11b.
Watering: Mature plants are very drought tolerant. From spring to fall, water thoroughly your Agave when the soil mix 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 Agaves a small amount of fertilizer in the spring during the first two years.
Repotting: When the pot becomes full of roots, it has become pot-bound. If you notice you Agave becoming pot-bound, repot it with new soil in a new pot that is just slightly larger than the old one.
Propagation: Since it can take years to produce seeds, Agaves are usually propagated by offsets.
Toxicity: Agave americana is not toxic to humans, but it may be mildly poisonous to children and pets.
