Ephedra nevadensis (Nevada ephedra) is a species of Ephedra native to dry areas of western North America.

Its range extends west to California and Oregon, east to Texas, and south to Baja California, including areas of the Great Basin, Colorado plateau and desert Southwest. It is found in rocky and sandy soils, generally in areas without trees.

More than other North American Ephedra species, it is a significant forage plant. It is grazed upon by mule deer (Ococolius hemionus), pronghorn (Antilocapra americana), and Desert Bighorn Sheep (Ovis canadensis) as well as domestic sheep.

Uses

Nevada ephedra was used for food and medicine by indigenous people and for tea by Mormons. Currently, its biggest use is as forage for sheep and cattle (it is not as good for horses), and for habitat restoration. It is sometimes grown for ornamental purposes. Among the Zuni people an infusion of the whole plant, except for the root, taken for syphilis. They also use it to make a tea-like beverage.

Reproduction

Nevada ephedra is wind-pollinated, with male plants growing in dryer areas and female plants growing in wetter ones, an arrangement which is believed to increase the production of seed. Cones mature and pollination occurs in March to June, with seeds ripening in May to August, although seeds are not produced every year. In the wild, seeds are often spread by rodents, and for cultivation, seeds can readily be collected and sown. The plant can also be propagated via transplants and cuttings.
