This medium- to large-sized century plant is native to rocky grassland slopes (often alkaline) from west Texas into Mexico (4,000'-6,000' elevation). A. havardiana forms a 3-4' wide glaucous, single rosette (rarely offsetting) of thick spiny leaves to 20" long and 6" wide...a very hardy species if protected from winter moisture when temperatures fall below the 20s. Mature specimens are topped with stunningly massive 12' tall asparagus-looking flower spikes in the summer months. Pot size: 24 fl. oz (709.77 ml)
Zone: 5-9
