A densely matted or tufted perennial plant, usually more or less pubescent. Flowering stems 4 to 10 inches high, simple or sparingly branched. Lower leaves and those of the numerous sterile shoots linear-oblong, close together, slightly narrowed at the base. Leaves of the flowering stems more distant, linear or narrowly lanceolate, one-half to 1 inches long, one-eighth of an inch wide or slightly wider. Flowers white, one-half to three-fourths of an inch broad, several in a cymose inflorescence. Petals five, obcordate or deeply notched at the ends, much longer than the lanceolate, acute sepals. Fruit a small, cylindrical capsule, a little longer than the sepals and slightly oblique at its apex.

In dry, rocky places, stony fields or ledges, Labrador to Alaska, south to Georgia, Missouri, Nevada and California. Also found in Europe and Asia. Flowering from April to July. In New York usually in bloom during some part of May.

This is a much larger flowered and more attractive plant than the Mouse-ear Chickweed (Cerastium vulgatum Linnaeus), which is naturalized almost everywhere, especially in the stony or rocky places where the Field Chickweed is found.
