It is extremely variable in morphology, its form depending on both genetic makeup and environmental conditions. It has a widely varying number of chromosomes. In general, it is a rhizomatous perennial herb forming mats or clumps, or growing erect. The stems may be short and simple or with sprawling and highly branched. The linear to lance-shaped leaves are usually 1 to 4 centimeters long and are oppositely arranged in pairs. The inflorescence bears one or more flowers, each on a short pedicel. The flower has five pointed green sepals each a few millimeters long. There are five white petals each divided into two lobes, sometimes shallowly, but often so deeply there appear to be two petals. The plant is gynodioecious, with some flowers having functional male and female reproductive parts and others being only female.
Stellaria nitens is a species of flowering plant in the family Caryophyllaceae known by the common names shiny chickweed and shining starwort.
