About
Calamagrostis x acutiflora 'Waldenbuch' is a deciduous perennial grass that forms clumps and gradually spreads, reaching a height of approximately 1.2 meters. It features glossy, mid-green leaves that arch gracefully. In mid to late summer, the plant produces airy, plume-like inflorescences in soft shades of pale purple-brown, which remain decorative through the winter months.
