Feather Reed Grass 'Waldenbuch'

Calamagrostis x acutiflora 'Waldenbuch' is a sophisticated cultivar of feather reed grass, cherished in UK gardens for its elegant, upright habit and early flowering. This grass forms distinct, vertical clumps of bright green foliage, from which strong, slender stems emerge in early summer, crowned with feathery, purplish-green flower plumes. These plumes mature to a beautiful golden straw colour, remaining upright and attractive well into winter, providing excellent architectural interest. 'Waldenbuch' is particularly valued for its sterile seeds, meaning it won't self-seed excessively. It thrives in full sun and various soil conditions, including heavier clays, and is drought-tolerant once established, making it a reliable and low-maintenance choice for borders, mass plantings, or as a striking vertical accent.
