Calamagrostis Karl Foerster is a stunning ornamental grass prized for its upright, clump-forming habit and tall, feathery flower plumes that sway gracefully in the breeze. This deciduous grass features narrow, green foliage that forms an elegant base, with vertical flower stems rising above from late spring to early autumn. The initially pinkish-purple flower heads mature to golden brown, providing seasonal interest well into winter. With its striking vertical form and delicate texture, Calamagrostis Karl Foerster brings height, movement, and structure to the garden year-round.

This versatile grass is perfect for adding vertical lines to garden beds, borders, or as an accent in contemporary or minimalist designs. Its tall, narrow habit makes it a wonderful choice for smaller spaces or as a backdrop for flowering perennials. Calamagrostis Karl Foerster is also ideal for prairie-style gardens, naturalistic planting schemes, and mass plantings where its rhythmic movement in the wind creates a sense of dynamism. It can also be planted in containers or used to create soft, informal screens or hedges.

Thriving in full sun, Calamagrostis Karl Foerster prefers well-drained soil with moderate moisture but is also quite adaptable to various soil types, including heavier clay soils. Once established, it is relatively drought-tolerant, though it will perform best with consistent moisture. Space plants approximately 60 cm apart to allow for its upright, spreading growth, ensuring air circulation and a natural grouping effect.

At maturity, Calamagrostis Karl Foerster typically reaches a height of 1.5 to 2 metres, with a narrow width of about 60 cm. Its tall, slender stems rise above its grassy base, creating a bold, vertical accent that provides year-round structure and interest in any garden setting.
