Atriplex are C-plants, with a characteristic leaf anatomy (kranz anatomy). The genus "Atriplex" is distributed nearly worldwide from subtropical to temperate and to subarctic regions. Most species-rich are Australia, North America, South America and Eurasia. Many species are halophytes and are adapted to dry environments with salty soils. The genus evolved in Middle Miocene, the C-photosynthesis pathway developed about 14.1-10.9 million years ago, when the climate became increasingly dry. The genus diversified rapidly and spread over the continents. The C"Atriplex" colonized North America probably from Eurasia during the Middle/Late Miocene, about 9.8-8.8 million years ago, and later spread to South America.
Gardening in restricted spaces When choosing which plants to include in the garden, there are several factors which should be considered. The growing conditions of the plant should be consistent with the conditions where the plant will be kept. The amount of upkeep required by the plant is also important. Gardeners with little time may want to choose plants that don't require a lot of attention while more gardeners who plan on devoting more time to the garden should choose plants that are more meticulous. Finally, the amount of money devoted to the project should also be specified. Some plants require more financial support
