USDA Symbol: PUST
Quininebush or cliff-rose is a freely branched, broad-leaf evergreen shrub growing 4-10 ft., depending on the site. The tubular flowers are creamy-white, five-petaled and extremely fragrant, eventually producing white, feathery fruits. Its bark is reddish and peeling. Leathery, pinnately compound leaves are green above, woolly-white below.
An attractive ornamental, Cliffrose is also planted for erosion control. It is an important browse plant for deer, cattle, and sheep, especially in winter. Native Americans used to make rope, sandals, and clothing from the shreddy bark and arrow shafts from the stems. It is called Quininebush because of the bitter-tasting foliage. This species is abundant on the south rim at Grand Canyon National Park, Arizona.
