CommentsThis is the only chickweed in Illinois that produces green flowers without petals, which makes identification easy. Apetalous Chickweed is similar to Stellaria meadia (Common Chickweed) in having ovate leaves, stems with lines of hairs, and a variable number of stamens in each flower. The flowers of Common Chickweed have deeply notched white petals, like many other chickweeds. It is not entirely clear how the seeds of Apetalous Chickweed are being dispersed across the state, although humans appear to have a major role. It is possible that the seeds become stuck in the muddy tire treads of motor vehicles, or they may cling to the bottom of shoes. The soil of horticultural plants often contain the seeds of weeds that flourish in nurseries, which may account for the appearance of Apetalous Chickweed and other weedy plants in flower beds.
