Korean Feather Reed Grass Overview

Calamagrostis arundinacea is a clump-forming deciduous perennial that produces grass-like green leaves that turn yellow in autumn. In late summer, plume-like sprays of fuffy purple-tinged flowers open that last into winter. Also known as Korean Feather Reed Grass, and Pheasant's Tail Grass, this popular ornamental grass is frequently listed Calamagrostis brachytricha under which name it earned a coveted Royal Horticultural Society Award of Garden Merit. They add great height and definition to borders and are very low maintenance making them great for beginners. Although tolerant of most conditions, these plants prefer well-drained soil in full sun, only needing their old foliage cut back to about 5cm above ground level in early spring.
