Foliage/texture: 2 to 3' slightly glaucous, strap-like leaves that hang or droop, flexible, sometimes tinged with red, coarse texture

Additional comments: This is a mesic yucca that prefers a little break from the hot western summer afternoon sun. It's surprisingly cold tolerant and is grown as an ormamental in even Europe. Here's an image of curve leaf yucca growing in an Orthodox monastery in Tryon, Bulgaria.
