Summary
Psorothamnus polydenius is a much-branched, spiny deciduous shrub usually growing 40 - 100cm tall, occasionally to 150cm. Older stems are leafless[1359 ]. Nevada smokebush (Psorothamnus polydenius) produces edible seeds, but only in very small, unreliable quantities. Its greater value lies in its fragrant flowers, traditionally used in tobacco mixtures. USDA Zones 8–10; native, not invasive.

Plant Habitats
Edible Uses
Nevada smokebush (Psorothamnus polydenius), also known as Nevada dalea, is a desert shrub native to the arid Southwest. Its seeds are reported to be edible, though, as with Emory’s dyebush, production is unreliable. During field observations, seed yields were meager or vanished quickly, making them of little practical value to foragers. This scarcity likely reflects the plant’s dependence on favorable rainfall for reproduction. While the seeds are technically edible, there are no records of them being a significant food source for Native Americans. Instead, the fragrant flowers of Nevada smokebush were more culturally important—they were added to tobacco mixtures, lending an aromatic quality to ceremonial and practical use. No other edible parts of this species are reported [2-3].

Plant Propagation
Like many species within the family Fabaceae, once they have ripened and dried the seeds of this species may benefit from scarification before sowing in order to speed up and improve germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing[K ].
