What is Agave americana (Century Plant) and how large does it grow?

Agave americana, also known as the Century Plant or American Aloe, is a dramatic succulent with large blue-green leaves and sharp teeth along the margins. At maturity, the rosette can reach 4-6 feet tall and 6-10 feet wide, with a flower stalk that may grow up to 20-40 feet tall.

How do I care for Agave americana in my garden?

This plant thrives in full sun and requires well-draining sandy or gravelly soil. Water deeply but infrequently, allowing the soil to dry between waterings. It is extremely drought-tolerant and low maintenance. Use a low-nitrogen, balanced fertilizer sparingly, and protect young plants from prolonged freezing temperatures.

Is Agave americana a good choice for xeriscaping or rock gardens?

Yes, Agave americana is an excellent choice for xeriscaping, rock gardens, and water-wise landscapes due to its extreme drought tolerance and architectural foliage. It serves as a striking focal point and is also suitable for large containers on patios and balconies.

When does Agave americana bloom, and what happens after flowering?

The Century Plant typically blooms after 10-30 years, producing a towering flower stalk with yellow-green flowers. After flowering, the main rosette dies, but offsets (pups) generally develop around the base which can be propagated to grow new plants.
