Mouse-ear chickweed (common mouse-ear, starweed)

Cerastium fontanum

A species of mat forming perennial, or rarely, annual plant. It is native to Europe but introduced elsewhere. Mouse-ear chickweed's identifying characteristics are tear-shaped leaves growing opposite one another in a star pattern, hairy leaves, and small white flowers. Mouse-ear chickweed typically grows to 4"-8" tall vertically and spreads horizontally along the ground via the formation of roots wherever the stem falls over and contacts the ground.
