We have a big yucca that came with the house 25 yrs ago. It's very hardy. Several times we've tried maintaining it with an axe. Literally! It's big so trying to cut some of the extra growth out with a shovel won't work. One time DH went a little overboard hacking at it. I thought it would have died but it produced 3xs the stalks the next year.Yuccas are easy to grow , comes back every year and seeds spread them around. Usually an ornamental but probably has some uses I would like to hear about.
