5 super cold hardy Agaves

Today I go into 5 cold hardy agaves that may be planted around the United States, as they are super cold hardy(-22F-10F) and can take snow, wind, high elevation and drought. They are Agave Utahensis, Agave Parryi, Agave Montana, Agave Chrysantha & Agave Havardiana. I give some info on their potential for use in the USA and why I love them.
