Calamagrostis brachytricha: The ornamental grass with silky plumes

Calamagrostis brachytricha, also known as feather reed grass, is an ornamental perennial grass highly valued for its airy floral spikes and soft texture. Its silvery-pink plumes, which bloom in late summer, bring light and movement to flowerbeds while offering a long-lasting autumnal display. Elegant, hardy, and easy to grow, it is perfect for natural, modern, or cottage gardens.

A graceful and luminous grass

This grass forms a dense and flexible clump of tender green foliage reaching 80 to 100 cm in height, and up to 1.2 meters when in bloom. Its feathery inflorescences, first pinkish then silvery, create a shimmering effect in the light. Its upright yet flexible habit allows it to add volume and movement to flowerbeds without being invasive. It pairs wonderfully with autumn perennials, rudbeckias, asters, or echinaceas.

Cultivation and care

Very easy to grow, Calamagrostis brachytricha prefers full sun to partial shade, and light, fertile, and well-drained soil that retains some moisture. It tolerates dry periods once established. Simply cut back the clump to 10-15 cm from the ground in late winter before new growth begins. This hardy grass can withstand cold down to -25 °C and requires no special care.
