  • Description

  • Notes

Adam’s needle (also commonly called Spanish bayonet, yucca, and needle palm) is a virtually stemless broadleaf evergreen shrub (though it looks more like a perennial than a shrub). It features a basal rosette of rigid, sword-shaped, spine-tipped green leaves (to 30” long and to 4” wide) with long curly threads along the margins. Leaves form a clump to 2 to 3 feet tall. In late spring, a flowering stalk rises from the center of each rosette, typically to 5 to 8 feet tall, but infrequently to 12 feet, bearing fragrant, nodding, bell-shaped, creamy white flowers. Fruits are capsules and are edible. Use in rock gardens, as an architectural accent, in a meadow-type planting, or planted among a mass of ornamental grasses. Evergreen.
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.
