Dasylirion wheeleri Ferns and Allies although they also perform wellThis surprisingly hardy yucca relative is absolutely exquisite! Each dramatically architectural, deer resistant clump will grow 3' tall x 4' wide with long, powder blue, gently twisting leaves. The spines are on the sides of the leaf not the tips. Instead, the end of each leaf forms a little cowlick curl like Elvis used to have (I mean, like Elvis STILL has somewhere!). If you are having trouble imagining this, think of a giant, blue braided Afro.
