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.
Hyacinthoides non-scripta late spring. They may also be found growing under bracken or Japanese knotweed, perennial plants which also form stands with a dense summer canopy. They are most successful on slightly acid soils; the same niche in alkaline conditions may be occupied by other species such as "Mercurialis perennis". As a species adapted to woodlands, the young shoots are able to penetrate through a thick layer of leaf litter, and bluebells are often used as an indicator species to identify ancient woodland. Bluebells are also frequently found in hedgerows, and in the west of their range they can be found growing
