Stellaria pubera Michaux. Common name: Star Chickweed, Common Starwort, Giant Chickweed, Great Chickweed. Phenology: Apr-Jun. Habitat: Bottomland forests, moist slopes, coves, hammocks. Distribution: NJ west to IL, south to Panhandle FL and AL.
ID notes: Both Stellaria corei and Stellaria pubera have an interesting seasonal growth form, producing short and relatively small-leaved flowering shoots in the spring (which wither following fruiting), followed by taller, more vigorous summer shoots with larger and tougher leaves and lacking flowers, which persist until autumn. Some of the description in various manuals of differences in petiole length and leaf size and shape between the two species is obscured or complicated by these seasonal differences; more careful observation is needed.

plant sale text: A name like star chickweed can strike fear in the hearts of gardeners but our native Stellaria pubera knows how to behave. It distinguishes itself from its troublesome relatives by larger, showier blooms and a perennial habit. Star chickweed does well in a woodland garden and is far more likely to spread by slowly creeping along the ground than by seeding in. This diminutive groundcover is common in the nearby woods, often found blooming in the company of green-and-gold, windflower, and dwarf crested iris. The genus Stellaria supports up to 15 lepidoptera species.
