Bush clover, also known as Lespedeza thunbergii, is a plant native to East Asia, specifically Japan and Korea. It is a deciduous shrub that typically grows to a height of 2-3 feet, with slender, branching stems. The leaves are trifoliate, with oval-shaped leaflets that are about 1-2 inches long. The flowers are small and pink or purple in color, and are borne in loose, elongated clusters.
In terms of growing conditions, bush clover prefers full sun to partial shade, and moist, well-drained soil. It is not winter hardy and will die back in cold weather, but it will regrow from the roots in the spring. To cultivate bush clover successfully, a gardener or farmer would need to provide it with the right conditions and protect it from frost.
Bush clover is not edible, and it has no known medicinal uses. However, it can provide value for wildlife, as the flowers are attractive to bees and other pollinators. The plant can also be used as a ground cover, as it spreads rapidly by underground stems. In Japan, it is often used in traditional gardens, where it is valued for its delicate flowers and graceful habit.
