DESERT SALTBUSH Desert saltbush (Atriplex polycarpa) is abundant in wide desert valleys and plains from southern California to central Arizona, often growing in pure stands. The tiny evergreen leaves are grey-coloured due to the deposits of salt excreted from hairs onto the leaf surface - an adaptation to prevent the build-up of salt in the plant tissues. This salt deposit helps to reflect light, shielding the leaves from excessive exposure to sun. In this species the leaves and flowers are often clustered.
