Hesperoyucca newberryi, commonly known as the Grand Canyon Quixote plant or Newberry's yucca, is a plant species endemic to Arizona. It is found only in Mohave and Coconino Counties, on the walls of canyons near the Colorado River.[2][3]

Hesperoyucca newberryi is a perennial forming a rosette. It is semelparous (flowering once then dying). Leaves are narrow, up to 60 cm (24 in) long but usually less than 3 cm (1.2 in) across. Flowering stalks are up to 160 cm (63 in) tall, bearing cream-colored flowers. The fruit is a dry, egg-shaped capsule about 4 cm (1.6 in) long.[2][4][5][6][7]
