Arctic Mouse-Ear

The Arctic Mouse-Ear (Cerastium arcticum) is a species in the genus Cerastium. Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Common Chickweed

<em>Cerastium fontanum</em>, commonly known as common chickweed, is a plant species found across Africa, Europe, and the Americas. It typically thrives in tropical and subtropical forest environments, as well as in disturbed habitats such as roadsides, gardens, lawns, and cultivated fields across a broad climatic range. The species is classified as Least Concern on the IUCN Red List, reflecting its cosmopolitan distribution and stable population status. Common chickweed belongs to the genus <em>Cerastium</em> within the family Caryophyllaceae. It is a low-growing, mat-forming herbaceous plant that typically produces small white flowers with deeply notched petals and is often found in moist, disturbed soils where it can establish rapidly. The species is a common garden weed in many parts of the world and is known for its ability to colonize a wide variety of substrates and environmental conditions. Biological traits such as average lifespan, plant height, and mass of this species remain poorly documented in the scientific literature. Its widespread occurrence and weedy habit contribute to its globally secure conservation status.
