Habitat & Geographic Range
Annual Sunflower
Inhabits montane grasslands and shrublands and Mediterranean forests and woodlands within the Palearctic biogeographic realm.
Widely distributed across Africa (12 countries), Asia (7 countries), Europe (30 countries), North America (Canada, United States), Oceania and the Pacific (Australia, Marshall Islands), and South America (4 countries).
Common corncockle
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.
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.
Annual Sunflower
One of the world's most cultivated flowering plants and an economically critical oilseed crop, sunflowers are native to North America and can reach 3 meters in height with flower heads up to 30 cm across. Their distinctive behavior of tracking the sun — solar heliotropism in young plants — gave them their name. A single sunflower head consists of up to 2,000 tiny individual florets. Global production exceeds 50 million tonnes annually, valued for oil, seeds, and birdfeed.
Common corncockle
<em>Agrostemma githago</em>, 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.
