Havard's Century Plant
Havard's century plant has proven to be a beautiful, cold-hardy garden plant at the Demonstration Garden despite being native to the warmer climate of west Texas.
It grows as a rosette of succulent, triangular leaves with toothed edges, each ending in a sharp spine. Each leaf is a soft blue-green color, which creates a nice contrast when placed close to lighter colored rocks or gravel.
This agave is very low-maintenance. Water it occasionally during summer and periodically remove debris that has collected at the base of the leaves with tongs. Since it doesn't lose its leaves in winter, it will create an architectural element in your landscape all year.
Once Havard's century plant reaches maturity after growing for 20-40 years, it will produce a large flowering stalk with yellow flowers. After it flowers, the individual plant will die.
