From a 1992 Yucca Do seed collecting expedition (YD 45-83) at 5,200' in Palmillo, Tamaulipas, Mexico, where Agave americana ssp. protoamericana intergrades with Agave scabra, we selected this particularly nice clone. Agave 'Silver Surfer' has since formed a 5' tall x 9' wide clump of stiff, outfacing, silvery-blue leaves. This slow-offsetting agave is a favorite of garden visitors, so we are thrilled to finally be able to list it in our catalog...get them while they last. Agave blooms attract hummingbirds.
