A: Cold hardiness of agave is an occasional problem down here in DFW, and more so as cold as it can get next to the Red River. We plant some types here you shouldn’t use, but here’s a list of some of our best varieties for you:
• Artichoke Agave: An agave with a rounder leaf, this plant will get 3’T x 3’W, and is cold hardy to 10 degrees.
• Havardiana Agave: One of the cold hardiest types period, 4’T x 4’W, hardy to -20 degrees!
• Neomexicana Agave: A more compact agave, grows 1 ½ ‘T x 1 ½ ‘W, another one good to -20 degrees!
• Whale’s Tongue Agave: A larger plant, gets 4’T x 4-5’W, good down to 0 degrees.
