About Spear Orache (Atriplex patula) Atriplex patula L. (Spear Saltbush; Common Orache; Spear Orach; Spreading Orach) is a ruderal, circumboreal species of annual herbaceous plants in the genus Atriplex naturalized in many temperate regions. Atriplex patula appears to have been a rather recent introduction in North America from Eurasia, not arriving perhaps until sometime in the early to mid-eighteenth century.
