field chickweed

Cerastium arvense is a perennial herb growing up to 30–45 cm (12–18 in) tall. It takes the form of a mat, clump, creeper, or upright flower, and may grow from a taproot or tangled system of rhizomes. It is usually somewhat hairy in texture, often with glandular hairs. The leaves are linear, lance-shaped, or oblong, and a few centimeters in length. The inflorescence may consist of a single flower to a dense cluster of many. The flower has five white petals, each with two lobes, and five hairy green sepals at the base. The fruit is a capsule up to 1.5 cm (0.59 in) long with ten tiny teeth at the tip, which contains several brown seeds.

Gardeners interested in wildflowers disagree on if field mouse-ears should be grown in gardens. Noted rock gardener Louise Beebe Wilder recommended against it in the strongest terms. However C.W. Wood and Claude A. Barr both thought that a specimen selected for good qualities had a place in a garden, such as a groundcover in difficult shady spots.
