Calamagrostis 'Karl Foerster': Vertical Feather Reed Grass

Calamagrostis 'Karl Foerster' – Architectural Grass for All Seasons

This versatile ornamental grass features slender, upright, deep-green foliage and purplish-green feathery plumes reaching 6 feet. A cool-season grass, it blooms in early summer (not fall) and requires winter chill to flower well.

Care & Maintenance

Cut old growth to the ground in early spring before new growth emerges. After a few years, the center may die out ("hole-in-the-doughnut" effect); dig and divide in spring to rejuvenate.

Landscape Uses

Excellent for hedges, screening, and vertical accents. Deer-tolerant and drought-tolerant once established.
