Habitat & Geographic Range

Common Chamomile

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate coniferous forests, and temperate broadleaf and mixed forests, among 7 distinct biome types spanning the Indomalayan and Oceanian and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (4 countries), Europe (19 countries), North America (Canada, United States), Oceania and the Pacific (Australia), and South America (Chile). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Didymous Chamomile

Habitat

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

Common Chamomile

<em>Anthemis arvensis</em>, commonly known as common chamomile, is a plant species found across Asia, Europe, the Americas, and Oceania. It typically occupies multiple biome types, often colonizing arable fields, disturbed ground, roadsides, and open grasslands in temperate regions. The species is classified as Vulnerable on the IUCN Red List, indicating that it faces a significant risk of extinction in the wild if the pressures affecting its populations continue. Common chamomile belongs to the genus <em>Anthemis</em> within the family Asteraceae and is an annual or biennial herb known for its white ray florets and yellow central disc flowers, which superficially resemble true chamomile (<em>Matricaria chamomilla</em>). The decline of this species is often associated with agricultural intensification, the widespread use of herbicides, and the loss of the traditional arable habitats it depends on across its range. Biological traits such as average lifespan, plant height, and mass of this species remain poorly documented in the scientific literature. Conservation efforts focusing on the preservation of low-intensity agricultural landscapes are important for the species' long-term survival.
