Kummerowia stipulacea, commonly known as Korean clover, is an annual herb that is native to grasslands, open woodlands, and roadsides in East Asia, including China, Japan, Korea, and parts of Russia. It has been introduced to the eastern United States, where it can behave invasively. This plant typically grows up to 24 inches tall and features prostrate, spreading, or erect stems with trifoliate leaves. The foliage is medium green, and the plant forms a low, bushy mound. It produces two types of flowers: cleistogamous, which are self-pollinating and not showy, and chasmogamous, which are purple-blue and more conspicuous, blooming in late summer.

Korean clover is valued for its ability to fix nitrogen in the soil, which can improve soil fertility. It is also used as a cover crop or for erosion control due to its fast growth and spreading habit. In cultivation, it prefers full sun to part shade and is tolerant of a wide range of soil types, though it thrives in well-drained soils. While it can be a useful plant in certain applications, it is important to be aware of its invasive potential outside its native range and to manage it accordingly to prevent unwanted spread.CC BY-SA 4.0
