The Little Mouse-ear (Cerastium semidecandrum) is a small perennial plant native to the United Kingdom, belonging to the Caryophyllaceae family. It is characterised by its tiny white flowers and densely hairy leaves, resembling those of a mouse’s ear.

Little Mouse-ear primarily grows in grasslands, coastal areas, and sandy habitats throughout the UK. It thrives in well-drained soils and is often found in open, sunny locations such as dunes, heathlands, and rocky outcrops.

In terms of food requirements, Little Mouse-ear is photosynthetic, relying on sunlight to produce energy. Its shallow root system allows it to access nutrients from the soil efficiently, enabling it to survive in nutrient-poor environments.

It provides important resources for pollinators such as bees and butterflies. Its flowers produce nectar, attracting these insects and aiding in pollination.

Little Mouse-ear typically has a lifespan of one to several years, with individual plants flowering annually during the growing season.

Culturally, Little Mouse-ear may not have significant references in folklore or traditional practices, but it is valued for its role in supporting biodiversity in grassland and coastal ecosystems.

An interesting fact about Little Mouse-ear is its ability to thrive in harsh, sandy habitats, where its low-growing, mat-forming habit helps stabilise soil and prevent erosion. Additionally, its small size and delicate flowers make it a charming addition to naturalistic gardens and rockeries.
