Avalanche Feather Reed Grass
What: Avalanche Feather Reed Grass (Calamagrostis x acutiflora ‘Avalanche’) is a dramatic ornamental grass featuring tall stalks of rose-colored plumes that rise above stiff green and cream variegated foliage. This fast-growing, low-maintenance perennial displays showy tan seed heads from late summer through winter.
Best use: Perfect as a vertical accent in landscapes, mass plantings, or as a stunning focal point in garden beds. Avalanche Reed Grass works beautifully in naturalized settings and woodland gardens, and its striking appearance makes it excellent for cut flower arrangements.
