It thrives in various soils—light, medium, or heavy clay—and prefers a pH between 6 and 7.5, making it adaptable to different growing conditions. Native to specific areas such as China North-Central, Japan, and Korea, this plant is known for its edible leaves, which can be consumed.

Its light and airy nature, with a height of up to 0.6 meters, makes it an interesting addition to gardens or natural landscapes where its dry-to-moist habitat requirements are met.
