Atriplex patula (spear saltbush; common orache; spear orach; spreading orach; /ˈɒrə/[1]) is a ruderal, circumboreal species of annual herbaceous plant in the genus Atriplex naturalized in many temperate regions. Atriplex patula is a member of the family Chenopodiaceae.[2]

Although it is commonly asserted that Atriplex patula has been naturalized in North America only since the eighteenth century,[3][4] seeds ascribed to this species occur on the west coast of North America in buried marsh deposits that predate European contact.,[5][6]

Description[edit]

Atriplex patula commonly grows along roads and waste sites.[7] It has a wide range, including semi-arid deserts and coastal areas in Asia, North America, Europe, and Africa.[2] It grows to be between 50 and 80 cm tall.[2] The branches extend outwards from the stem with rhomboid leaves and separated clusters of flowers.[2] Atriplex patula accumulates salt from the environment in its tissues. Unlike other Atriplex species, A. patula does not have notable salt bladders to excrete salt onto the leaves.[8]

Uses[edit]

Atriplex patula has been proven to be effective in lowering salt content in soils when planted in areas with high road salt contamination.[8]
