I like this combo of Mojave Yuccas with the flowers at their base.

Native Americans of the Southwest traditionally used Mojave yucca for numerous purposes. Fruits were eaten raw or dried for later use. Leaves, which contain high levels of saponin, a detergentlike substance, were pulped to produce soap. Fibers obtained from the leaves were made into rope, twine, hats, hair brushes, shoes, mattresses, and saddle blankets.
