I know this plant as Yucca guatemalensis with Synonyms of Y. elephantipes and Y. gigantea. I'm not sure which is actually correct, but Spineless Yucca, a/k/a Giant yucca can grow to heights of 30'. It has the white bell-shaped blooms of other Yuccas and long 4' serrated leaves. With age, the trunk becomes thick and develops a swollen base with branches near the base.

I have a few of these Spineless Yuccas in my yard. The original came from a lopped-off stem of a neighbor's plant a couple of years ago. Cuttings root easily and I have shared a few with family, friends and other neighbors. In my experience, the ones planted in full sun grow much faster than those in shady locations.

My neighbor is from Guatemala where they harvest the flowers and cook them with eggs.
