Plant of the Month

Agave scabra

by Mark Weathington, Assistant Director and Curator of Collections

Agave scabraFew plants evoke the feel of the Southwest more than Agave and with good reason. Mexico is the center of diversity for this genus and contains about half of the 200–250 species with the rest scattered through the United States, Central America, and the Caribbean. Agaves typically grow on rocky hillsides in exposed, sunny spots but some species will occur in forested areas especially oak woodlands and even occasionally in mixed forests where they will grow on thin rocky or sandy soils. In all cases, the soil drains quickly.

Agave scabra is a medium-sized agave valued for its architectural form and bluish-green to gray-green leaves which are viciously armed on the margins and tips. It is known as the "rough" agave due to the rough (or scabrous) texture of the undersides of the leaves. Our plant is flowering this year as our fans on Facebook are already aware. The thick flower stalk, invariably described as asparagus-like, has shot to about 15', is branching and will soon be flowering with bright yellow flowers. The species ranges from Texas south through Mexico to the Pacific Ocean and from 500' elevation to 6,500' so provenance of parent plants is most likely important to determine hardiness.
