The yuccas comprise the genus Yucca of 40-50 species of perennials, shrubs, and trees in the agave family Agavaceae, notable for their rosettes of evergreen, tough, sword-shaped leaves and large terminal clusters of white or whitish flowers. They are native to the hot and dry parts of North America, Central America, and the West Indies.
Yuccas have a very specialized pollination system, being pollinated by the yucca moth; the insect purposefully transfers the pollen from the stamens of one plant to the stigma of another, and at the same time lays an egg in the flower; the moth larva then eats some of the developing seeds, but far from all.
