Plant
Weak-leaf Yucca
Yucca flaccidaAlso known as Adam's Needle, Flaccid-Leaf Yucca, Beargrass
Weak-leaf yucca forms rosette clusters of pliable, fibrous evergreen leaves that bend or fold downward under their own weight. In early summer, tall flowering stalks rise up to two meters high, bearing nodding bell-shaped white blossoms. These flowers rely on a specialized obligate mutualism with yucca moths for pollination, where female moths actively transfer pollen before laying eggs in the developing seed pods.
