Adam’s Needle (Yucca Filamentosa)

Adam's Needle

Features and Characteristics

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 has escaped cultivation and extended its original range north into New England. 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.

Genus name comes from the Carbi name for manihot, also called cassava or yuca, which is not closely related but has similarly enlarged root structures.

Specific epithet means with filaments or threads.
