Yucca baccata

Because Yucca baccata occurs in a wide range in much of the south western USA and northern Mexico, it is a variable species. It has also a large range in elevation: from 600-2450 m. There are small-trunked cluster forming plants that develop rosettes of 5-50 heads, developing clumps way over 2 meters. The leaves also vary considerably in colour: There are blue-green forms and grey-green from western Texas and bordering regions in New Mexico and completely blue forms from Nevada and Arizona. Y.baccata is a very cold hardy yucca down to -29°C what makes it a widely used plant.
