Mouseear chickweed acts as a winter annual in eastern North Carolina and as a perennial in the western part of the state, especially at higher elevations. It has a vigorous prostrate growth habit. Hairy stems may creep along the ground and take root at nodes touching the soil. The small, white flowers have five slightly notched petals. Mouseear chickweed is similar in growth habit (spreading) and appearance to common chickweed, but mouseear chickweed leaves are dark green or gray-green, and are covered with soft hairs.
