This is one of the first annual plants to bloom during the spring, although it is often overlooked by passersby. This species is unique because of the jagged tips of the petals; other closely related species in the Pink family with small white flowers have petals that are notched, deeply divided, or smooth along their tips. The foliage of Jagged Chickweed is more bluish green or greyish green than the foliage of most Cerastium spp. (Mouse-Eared Chickweeds) and Stellaria spp. (Chickweeds). The indentation of the seeds is another unusual characteristic, although this requires a good hand lens to see.
