Karl Foerster Feather Reed Grass (Calamagrostis × acutiflora ‘Karl Foerster’)

Karl Foerster Feather Reed Grass is a widely used ornamental grass known for its strong vertical form and adaptability in a range of landscape settings. This sterile hybrid cultivar of Calamagrostis × acutiflora is valued for its upright growth habit and reliable performance in both residential and commercial plantings.

This deciduous, clump-forming grass produces narrow green foliage that forms a dense, upright base. In early summer, it sends up tall, feathery flower plumes that emerge with a soft purplish tint and gradually mature to a golden tan, persisting well into fall and often through winter for extended seasonal interest.

Karl Foerster is commonly used in landscape design for structure, screening, and vertical contrast. It performs well in mass plantings, borders, and modern garden designs, and is also suitable for container use. Its consistent form and long-lasting plumes make it a staple in both formal and naturalized plantings.
