Calamagrostis x acutiflora 'Karl Foerster' 

Karl Foerster Feather Reed Grass is a classic ornamental grass prized for its tall, narrow form and exceptionally upright growth habit. Fresh green foliage emerges early in the season, followed by elegant, wheat-like flower plumes in late spring to early summer. The plumes start soft and feathery, then gradually mature to warm golden tones that stay attractive into fall and winter.

Perfect for adding height and vertical structure without taking up excessive space, Karl Foerster works beautifully in borders, foundation plantings, mass plantings, and mixed perennial beds. Its graceful movement contrasts beautifully with flowering perennials and broad-leaved plants, while its tough, adaptable nature makes it an excellent low-maintenance landscape choice.

Growing Tips

Plant in full sun for the strongest, most upright growth. Karl Foerster adapts to a variety of soil types and can tolerate heavier clay as long as drainage is adequate. Water regularly during the first growing season, then provide supplemental water during extended dry periods. Leave the dried foliage and flower plumes standing through winter for seasonal interest, then cut the plant back to about 4–6 inches in late winter or early spring before new growth begins.

Dependable, graceful, and incredibly versatile, Karl Foerster Feather Reed Grass brings height, movement, and year-round structure to landscapes of nearly any size.
