Calamagrostis × acutiflora ‘Karl Foerster’

Calamagrostis × acutiflora ‘Karl Foerster’ is one of the most widely grown and dependable ornamental grasses, valued for its strong upright habit and elegant vertical lines. Narrow green foliage forms a tight clump, from which tall, slender stems rise in early summer carrying soft, feathery flower plumes that emerge pinkish before maturing to warm buff tones.

Long-lasting and structural, the flower spikes persist well into winter, providing height, movement, and year-round interest in the garden. Ideal for mixed borders, prairie-style planting, and contemporary schemes, ‘Karl Foerster’ combines beautifully with perennials and is particularly effective when planted in drifts or repeated through a border.
