Calamagrostis acutiflora 'Avalanche'

Common Name: Variegated Feather Reed Grass

A striking, upright ornamental grass valued for its bold variegated foliage and strong vertical form. Narrow green blades are edged with creamy white, creating bright contrast from spring through fall. In early summer, airy flower plumes emerge soft pink, maturing to tan and persisting into winter for extended seasonal interest.

Growth is clump-forming and well-behaved, maintaining a tidy, architectural habit without spreading or flopping.
