Aster koraiensis, commonly known as Korean starwort, is an herbaceous perennial native to the Korean peninsula, where it thrives in a variety of habitats including open woodlands, grasslands, and along streams. It typically grows to a height of 20-24 inches and features alternate, lanceolate leaves. The pale violet flowers are star-shaped, with an inflorescence head about 1.6-2 inches wide, and bloom from June to September, adding a delicate touch to the garden during the summer months.

Korean starwort is valued for its long blooming period and the subtle beauty of its pale violet flowers. It is often used in naturalized plantings, borders, and as a component in cottage gardens. In addition to its ornamental uses, it is utilized in food preparation and for erosion control due to its robust root system. This plant prefers moist, well-drained soils and can tolerate a range of light conditions from full sun to part shade. While generally low-maintenance, it can be susceptible to powdery mildew and should be monitored for this disease.CC BY-SA 4.0
