Agave havardiana is a native species found exclusively in the Glass Mountains of west Texas. It forms a single rosette, usually 3-4' wide, of thick, spiny, glaucous blue leaves that can grow up to 20" long and 6" wide. This hardy plant is well-suited to withstand temperatures below 20 degrees F by being protected from winter moisture. During the summer, mature specimens produce impressive 12' tall flower spikes that resemble asparagus, adorned with large clusters of vibrant yellow flowers, attracting various pollinators.
