Description:

Adam’s Needle, or simply Yucca, is a broadleaf evergreen shrub with a unique form. It features yellowish-white flowers, which bloom in clusters on 3- to 6-foot panicles reaching above the foliage, May-July. The flowers attract bees and butterflies. The leaves are thick, fibrous blades, which extend both vertically and horizontally from the center of the basal stem, terminating in a sharp point — like a needle. Adam’s Needle is a host plant for butterfly and moth larvae (caterpillars), including Yucca Giant-Skipper (Megathymus yuccae) and Cofaqui Giant-Skipper (Megathymus cofaqui). Yucca perfers dry, sandy soil and is drought-tolerant, making it a good choice for New Jersey yards. Plant Adam’s Needle in groups as accents, around foundations or borders, or as stand-alone specimens in your yard.
