I have a soapweed yucca growing in my south-facing flowerbed. It seems to be doing well in the dry clay soil. Now in its second year, it's slow-growing and hasn't bloomed yet. I would expect it to take some time to get to an appreciable size, given our short summers and long, cold winters.

This yucca grows all over Oklahoma and is native to the area I live. The leaves are very tough and hard to cut especially with a dull pair of clippers. I have one I dug up just outside of town and hasn't bloomed since I have had it but it is much bigger than when I first got it.

American Indians used the pounded root as a poultice on inflamations and to stop bleeding. They also used it as a shampoo to cure dandruff and baldness. The leaf juice was used to make poison arrows.

I disagree with palmbob--I find this yucca extremely attractive--attractive enough to merit an "ooh! what's that????" at our local arboretum and a quick trip to a nearby nursery that specializes in dryland plants. It's proven very hardy and very drought-tolerant.
This Yucca is native further north than any other. It grows into Alberta (and Saskatchewan), Canada (Which by the way is zone 3a, with occasional 2b winters. Despite common belief this Yucca does from a trunk. The trunk grows slowly to about 2 feet. It is not monocarpic, as parent plants set seed many times before dieing. I personally can vouch for flowering and seeding of the same plant for 5 seasons.
This is a much better plant than people give it credit for, and its hardiness is UNMATCHED among Yuccas, it is hardier even than Yucca filamentosa and flaccida.

Not a terribly ornamental plant- looks a bit like a clump of grass with slightly spiny ends. Common all over the south and midwest into the plains of the US.
