Common Soapwort

Notes:

It was originally introduced into the United States from Europe for horticultural purposes. Habitats include sloping banks of streams, gravel bars and sand bars along streams, areas along roadsides and railroads, prairie remnants along railroads, weedy meadows, and waste areas. Soapwort is still cultivated in flowerbeds and herbal gardens. While this plant is typically found in disturbed areas, it also occurs in some natural areas, where it can become a pest.
