Cerastium glomeratum, commonly known as Sticky Mouse-ear Chickweed and Clammy Chickweed, is an annual herb native to a variety of habitats including grasslands, meadows, open woodlands, and rocky areas in Europe, Macaronesia, and as far east as Assam. It has become naturalized in many other parts of the world, often found in disturbed sites such as waste places, walls, banks, and arable land. This plant typically grows up to 18 inches tall and is characterized by its hairy stems and foliage, with both glandular and non-glandular hairs. The leaves are opposite, up to 1 inch long, and the basal leaves often die back before the plant flowers. The inflorescence is a cyme that bears 3 to 50 small, dioecious flowers, each with 5 hairy green sepals and 5 white bifid petals that bloom in the spring and summer months.

Sticky Mouse-ear Chickweed is valued for its ability to thrive in poor soils and its use as a ground cover in garden settings. It requires minimal maintenance and can tolerate a range of light conditions, from full sun to partial shade. It prefers well-drained soils but can adapt to various soil types. While it is not commonly used for ornamental purposes, its resilience makes it a suitable choice for challenging areas where other plants might struggle to grow. However, gardeners should be cautious as Cerastium glomeratum can be potentially invasive outside its native range, and it is advisable to check local regulations before planting.CC BY-SA 4.0
