Grow Korean Feather Reed Grass: Full sun or part shade for heaviest bloom and tightest, upright growth.

Dig Deeper: Korean Feather Reed Grass is a long-lived, clumping grass which adapts to most soil types — performs best in fertile, moist soil. Plants tolerate poor drainage and heavy clay soils — even bog-like conditions, as found next to ponds and streams. Stands up well to salt and humidity, will grow near black walnut trees, and is highly resistant to deer and rabbits. Plumes are beautiful additions to fresh or dried flower arrangements. Winter seed heads attract birds.

Use Korean Feather Reed Grass at the back of mixed borders, in containers, or group together among shrubs as striking vertical accents. Mass plantings of Korean Feather Reed Grass are especially showy. In late winter or early spring, cut plants back to within a few inches of the ground to provide room for new growth. Will sometimes self-sow. Korean Feather Reed Grass is a recipient of the Award of Garden Merit given by the Royal Horticultural Society.
