Many of the agaves for sale in our area are Zone 9, meaning that they need winter protection if temps drop into the low 20's. Some varieties can't take a freeze at all!
The ones listed below are all 8b and lower, meaning that they will probably take temperatures down to 15°F without protection. If the freeze is early and severe, protect them anyway.
We will list a few agave here that have proven to do well in Austin and the surrounding regions.
