  • Description

  • Notes

Harriman yucca is a striking accent in a dry, naturally-styled landscape. Leaves are evergreen, sword-like, narrow and tappering to a point, with sharp tips, and form clumps to 3 feet tall and wide (though they do colonize over time and can become wider). Flower spires are up to 5 feet tall and are lined with bell-shaped, creamt flowers tinged with purple. The leaves are used to make a course rope.
Grow in well drained, sandy-gravelly soil in full sun, though is surprisingly tolerant of some part shade. No maintenance is needed, though you can remove the flower scape after the plant has finished blooming. The leaves are spiny, so plant it where it won't interfere with a walkway. Yucca are clumping, and so in time will form large colonies. Frost tolerant to -20 F.
