The bleached plumes of Calamagrostis actifolia Avalanche wave elegantly on long stems from summer to autumn, adding height to a border or focus to a prairie planting scheme. In the winter these plumes catch the frost to magical effect. This clump forming grass, with attractively striped, dark green foliage, can grow to 2m tall if the soil is moist.


The name Calamagrostis is a happy mix of the Greek word for weed and grass. It is widely indigenous across parts of Europe and Asia. An architectural ornamental grass, if planted in rows it can form a useful screen but is valued especially for adding movement to a border, catching, as it does, every breeze.
