A native groundcover, this plant is known for both its foliage and flowers with toothed, light green, triangular leaves and dark yellow, slightly notched, star shaped flowers that bloom well above the foliage and have contrasting brown stamens. The flowers bloom abundantly in the spring and fall, but tend to die down in the heat of the summer except in the cooler zones.
Fuzzy blue flowers atop attractive red stems, in September and October, make great cut flowers. This plant can be aggressive in Southern gardens. Found in old fields, meadows, and along stream banks. Naturalizes readily.
