| | Yucca is a genus of about 40 species ofAgave relative native of dry areas of North America. They form rosette of stiff leaves, and many develop a wooden trunk that can branch and become tree-like. The genus name "Yucca" is the Arawak name for the Tapioca (Manihot esculenta) of which genus Yucca was mistaken for. The flowers are white or cream and organized in panicles. The branch or the plant that produced the flower does not die after blooming. The flowers have to be pollinated by the yucca moth to bear fruit. There is a distinction between Yucca defined by the fact that the fruit is either fleshy (like the Banana Yucca) or dry. The frost resistance of Yuccas varies a lot depending on the species. Some species are extremely frost resistant, growing in the northern parts of the United States, up to Canada. Some species are frost tender. All the species prefer full sun and a good drainage.
