Grass-poly is a delicate annual or short-lived perennial that thrives in moist, open habitats such as pond margins, wet meadows, and damp garden borders. It prefers full sun to partial shade and consistently moist soil, making it ideal for rain gardens or the edges of water features. This modest but charming plant produces small pink to purple flowers and has some historical medicinal use in traditional herbal practices.
