Agave havardiana (Havard's Agave)

Havard’s  Agave is an attractive medium size, rosette-forming agave that is noted for its attractive blue-gray evergreen leaves. It is native to the Chisos mountains of Big Bend National Park. Havard’s Agave is very drought tolerant and requires excellent drainage. Poorly-drained soils inevitably lead to root rot. It is hardy to at least 5 degrees Fahrenheit. Plants have reportedly survived winters with temperatures as low as -10F, but cold temperatures should be "dry cold" as opposed to "wet cold". Agaves create strong architectural accents and do very well planted en masse or used as a focal point.   AT A GLANCE Texas native Yes Water use Low Sun exposure Full sun, part sun Bloom color Yellow-green Mature height 2-3 ft Mature spread 3-4 ft Evergreen  Yes Notes Sharp spines.
