Forage kochia (Kochia prostrata (L.) Schrad.), also known as prostrate kochia, or prostrate
summer cypress is a long-lived, perennial, semi-evergreen, half-shrub well adapted to the

Saltbush is a vernacular plant name that most often refers to Atriplex, a genus of about 250 plants distributed worldwide from subtropical to subarctic regions. Atriplex species are native to Australia, North and South America, and Eurasia. Many Atriplex species are halophytes and are adapted to dry environments with salty soils.

Atriplex Halimus

The leaves are edible. Extracts from the leaves have shown to have significant hypoglycemic effects.

The species has potential use in agriculture. A study allowed sheep and goats to voluntarily feed on A. halimus and aimed to determine if the saltbush was palatable, and if so, did it provide enough nutrients to supplement the diet of these animals. In this study they determined when goats and sheep are given as much A. halimus as they like, they do obtain enough nutrients to supplement their diet – unless the animal requirements are higher during pregnancy and milk production....
