Plant Profile: Calamagrostis brachytricha

Calamagrostis brachytricha, commonly known as Korean Feather Reed Grass, is a decorative warm-season grass characterized by its upright, arching growth habit. This grass gradually forms clumps adorned with glossy, green leaves that are about half an inch wide. In late summer, it produces pink-tinged plumes atop stems that can grow up to 4 feet tall. As the seeds mature, these plumes transition to a light tan color but typically break apart by early winter. Even when dry, the grass retains an open and feathery appearance, making it suitable for both fresh and dried floral arrangements. While it naturally reseeds in moist, shaded woodlands, it remains easy to manage.

This grass thrives in average to medium-wet soils and prefers partial shade, although it can also tolerate full sun if adequately watered. Its ability to flourish in heavy clay soils sets it apart from many other ornamental grasses, making it an excellent choice for gardens in North Carolina. It is essential to keep the soil consistently moist, avoiding any drying out. In light shade, it will bloom well, and in hot southern regions, it benefits from afternoon shade. For optimal growth in spring, it is advisable to cut the grass back to the ground in late winter before new shoots emerge.

Additionally, this plant is resistant to deer browsing.

Regarding pests and diseases, Calamagrostis brachytricha does not face significant issues from insects or diseases.
