This is one of the more attractive Chickweeds, particularly when it occurs in colonies, because the attractive flowers are produced in great abundance and the foliage is elegant and grass-like. It has a similar appearance to the native Stellaria longifolia
(Long-Leaved Stitchwort). However, this latter species has sepals that are without conspicuous veins or hair, and its seeds have a smooth surface. Long-Leaved Stitchwort produces flowers less abundantly than Grass-Leaved Chickweed, and some of its flowers develop from the axils of the leaves. There are many other Stellaria spp.
(Chickweeds), as well as Cerastium spp.
(Mouse-Eared Chickweeds), but they often have broader leaves and hairier foliage. Another common name for Stellaria graminea
is Common Stitchwort.
