Discussion

Shepherdia rotundifolia is an attractive shrub of the southwestern deserts of North America; it grows on rock ledges or slick-rock sandstone habitats where the rounded growth form and bright silver indument are distinctive. Drought tolerance makes it a good candidate for gardens in arid regions; it has been planted in some botanical gardens.
