Nursery contributed plant descriptions

A robust, stout, particularly silver-blue form from northeastern Mexico, the 6' or larger rosettes have proven a bit more moisture and cold resilient than its cousins. Surviving temperatures of 10 to 15 °F with good drainage, it reaches its greatest potential in large containers or in the open ground. Makes a fine focal point.
