Yucca filamentosa, commonly called Adam’s needle, Spanish bayonet, yucca and needle palm, is a virtually stemless broadleaf evergreen shrub (though it looks more like a perennial than a shrub) that is native to beaches, sand dunes and fields from South Carolina south to Florida and Mississippi. It features a basal rosette of rigid, sword-shaped, spine-tipped green leaves (to 30” long and to 4” wide) with long filamentous (as per specific epithet) curly threads along the margins. Leaves form a foliage clump to 2-3’ tall. In late spring, a flowering stalk rises from the center of each rosette, typically to 5-8’ tall, but infrequently to 12’ tall, bearing a long terminal panicles of nodding bell-shaped creamy white flowers. Fruits are elliptical dehiscent capsules. Will form a small colony over time from basal offsets. Borders. Dry garden areas. Dry slopes. Adds architectural height. Also may be grown in large containers. Suitable for seaside gardens or areas which receive road salt runoff. Easily grown in light, dry to medium, well-drained soils in full sun. Tolerant of poor, sandy soils, heat, drought, and salt spray. Surprising tolerance for some part shade. Hardy in zones 5-10.
