Calamagrostis × acutiflora ‘Avalanche’

Feather Reed Grass

USDA Zone: 4-9

Plant number: 8.080.090

A variegated selection of Feather Reed Grass, suited to a multitude of uses and not invasive in any way. Green leaves are striped down the middle with white, developing a decent sized clump by mid to late spring. Soft feathery greenish-mauve plumes appear in early to midsummer, maturing into stiff wheat-coloured spikes, which last into winter. May be used in large groupings towards the back of a border, but also very effective when used more as a single specimen. Hardy enough to survive in containers or tubs in many regions, and likely to survive outside in Zone 3 or colder. Clumps may be easily divided in spring. Trim to the ground in March. Cool-season. A sport from the extremely popular selection ‘Karl Foerster', discovered by Steve Schmidt in Oregon. Better impact and vigour than ‘Overdam'.
