This is a controversial species from southern Arizona and northern Sonora, Mexico. Some think this is a hybrid of Yucca baccata, which it does not resemble in any way, shape, or form; others think it is a hybrid of Yucca madrensis, which Y. arizonica resembles. Whatever the discussion, this is a very real Yucca that forms a short tree with a rosette of flexible, relatively wide leaves. It can take considerable frost, perhaps down to 0F. These plants are seedlings in 3-gallon pots.
