Reed canary grass is a cool-season perennial that transforms wet and challenging sites into lush ground cover, thriving where most ornamentals struggle. Native across North America, Europe, Asia, and North Africa, this upright rhizomatous grass grows 24 to 36 inches tall and equally wide, with showy blooms arriving in June and July. Hardy from zones 4 through 9, it tolerates everything from wet soil and clay to drought and urban conditions, making it equally at home in rain gardens, naturalized areas, or along water margins. The 'Feesey' variety offers moderate maintenance demands and a robust constitution that rewards minimal fussing once established.

Reed canary grass is a problem-solver for problem places. It spreads steadily via rhizomes to fill large areas quickly, asking for just four plants per square yard to cover ground rapidly. The combination of moderate water needs, remarkable soil tolerance, and ability to thrive in wet conditions where few grasses succeed makes it invaluable for rain gardens, stream banks, and wetland restoration. Its rhizomatous nature is both its strength and something gardeners need to plan for, but containment strategies allow you to harness this vigor without letting it rampage.
Reed canary grass serves three primary landscape roles. It naturalizes disturbed areas, stream banks, pond margins, and wetland edges with minimal intervention. It functions in rain gardens, where its moderate water tolerance and clay-soil resilience help manage stormwater. It also works as a ground cover for large areas, particularly where traditional turf grasses falter in wet or compacted soil.

Divide established plants in spring and transplant into prepared soil. Space divisions at four plants per square yard for rapid ground cover establishment. No hardening off is necessary; rhizomatous perennials transition directly from nursery to garden.
Direct sow seed in spring into average to moist soil in full sun to partial shade. No special stratification is mentioned in sources.
