Habitat & Geographic Range

Common corncockle

Habitat

Found across multiple habitat types including montane grasslands and shrublands, tropical and subtropical moist broadleaf forests, and temperate coniferous forests, among 13 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Lesotho), Asia (7 countries), Europe (24 countries), North America (Canada, Mexico, United States), Oceania and the Pacific (Australia), and South America (Brazil, Chile). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Orache

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Widely distributed across Asia (Georgia), Europe (13 countries), North America (Canada, Mexico, United States), Oceania and the Pacific (Australia), and South America (Chile).

Common corncockle

Agrostemma githago, commonly known as common corncockle, is an annual flowering plant in the family Caryophyllaceae. Once a widespread weed of cereal crops across Europe, Asia, and beyond, this species is now Critically Endangered on the IUCN Red List due to the dramatic decline caused by modern agricultural practices, particularly improved grain cleaning and herbicide use. Corncockle is a tall, slender plant covered in silky white hairs, bearing large, solitary pink to purple flowers with distinctive dark veining. Its seeds contain toxic saponin compounds called githagins, which historically contaminated grain supplies. The species now survives primarily in wildflower conservation areas, seed banks, and traditional farmland conservation schemes. It typically grows in open, disturbed arable soils with full sun exposure. Biological traits of this species remain poorly documented in the scientific literature.

Common Orache

Atriplex patula is an annual herb in the family Amaranthaceae, distributed across Europe, Asia, North America, Australia, and Chile. It typically colonizes disturbed habitats, coastal areas, salt marshes, roadsides, agricultural fields, and waste ground, tolerating saline soils that many other species cannot withstand. The species is halophytic, possessing physiological adaptations for salt tolerance, including salt-excreting glands on its leaves. Its range extends across Georgia in Asia, thirteen European countries, and introduced populations in North America, Australia, and South America. Orache produces small, inconspicuous flowers and characteristic mealy-textured leaves. It is sometimes used as a leafy vegetable in traditional cuisine across parts of its native range. The IUCN lists this species as Least Concern given its widespread occurrence and adaptability to multiple habitat types. Biological traits including average lifespan, body measurements, and detailed dietary ecology remain poorly documented in standardized databases for this weedy annual species. Atriplex patula plays a functional role in stabilizing disturbed soils and contributing to coastal and ruderal plant communities across its broad distribution.
