Adam's needle yucca is a broadleaf shrub native to the southeastern United States (Maryland to Tennessee, south to Florida and Louisiana) reaching 4 ft with rounded form. It produces yellowish-white flowers (5-7 cm) in narrow, spike-like panicles 2 m or taller.

Adam's needle yucca is hardy in zones 4a-8b and thrives in full sun to part shade with moist, adaptable soil (pH 4.5-8.5). Growth is medium-paced with low maintenance. It tolerates deer, drought, erosion, shallow rocky soil, and urban conditions. Roots contain saponins (toxic if ingested raw but destroyed by heat).
