If this is agave americana protoamericana, it is cold hardy to zone 7. I have several growing in my yard and it's quite popular as a landscape plant here. It gets almost as tall as agave americana. The leaves on this tend to be slightly wider and shorter than agave americana creating a nice urn shape.

I have not grown this plant. This is a very large ornamental plant. Most Agave experts believe it to be the possible prototype of Agave americana. It is native to Nuevo Leon, San Luis Potosi, Tamaulipas, Texas. It is not frost tolereant.
