Sarcobatus is a genus of two North American desert shrubs, mainly Black Greasewood (S. vermiculatus), that tolerate salty, alkaline soils. They are hardy, deciduous, and rarely grown in gardens; the key to them is dry, saline, well-drained ground and full sun.

Family
Sarcobataceae (Sarcobat family)
Light
Full sun
Water
Water sparingly once established; it is adapted to drought and saline soils.
Soil
Sandy or gravelly, well-drained soil; tolerates alkaline and saline soil.
Temperature
Hardy to well below freezing; tolerates hot desert summers and cold winters.
How easy
Easy
Safety
Toxic: Foliage contains oxalates, which can cause poisoning in grazing animals and may harm people who eat large amounts.

About

Sarcobatus is a North American genus of two species of flowering plants, formerly considered to be a single species. Common names for S. vermiculatus include greasewood, seepwood, and saltbush. Traditionally, Sarcobatus has been treated in the family Chenopodiaceae, but the APG III system of 2009 recognizes it as the sole genus in the family Sarcobataceae.

Where it grows

The Sarcobatus area of distribution is western North America, from southeastern British Columbia and southwest Alberta, Canada south through the drier regions of the United States (east to North Dakota and west Texas, west to central Washington and eastern California) to northern Mexico (Coahuila).

Uses

Although it can be grazed by animals that are adapted, grazing of greasewood by sheep and cattle can result in oxalate poisoning resulting in kidney failure. The active agent can be either sodium oxalate or potassium oxalate. Sheep are the most vulnerable.
