Yucca aliofolia in Nashville
This is my Yucca aliofolia. Believe it or not, I found these yuccas, at half their size, on the side of the road in my neighborhood- ready for the trash. The people tore them out to put in a pool. I asked if I could take them and they all rooted well. I cut off all the bent and broken leaves (from them being ripped out of the ground and trashed) and I just kept trimming them over the months to maintain shape. This is another plant that stores might tell you is not hardy but I have never lost even one to the cold.
