Korean Feather Reed Grass- Feathers for your Garden!
(Calamagrostis brachytricha) Is an excellent addition to your garden for fall interest. It puts on a show after many other plants have quit for the season. Korean feather reed grass produces large (12”) plumes with a pink tinge in August and matures to a tan color. These plumes can be cut and used in dried arrangements. The leaves grow to 36” tall with the plumes held above the leaves to a height of 48”. The base of the slow-spreading mound will be about 15” across. While it’s in bloom, the clump can reach 24” across. Korean feather reed Grass’s growth habit and feathery plumes are more rounded and fuller than other more common (and often overused) Calamagrostis varieties.
Korean feather reed grass likes full sun or partial shade. It is native to moist woodlands of central and eastern Asia, and it tolerates heavy clay soil which helps keep the roots moist. While Korean feather reed grass will go quite dry, it does need additional irrigation at times in the Denver area. Cut it to the ground in early spring for a beautiful fresh look for the new season.
The leaves will eventually turn to a bright yellow late in the fall. Pair Korean feather reed grass with other great fall-blooming plants like Plant Select’s Zauschneria ORANGE CARPET® or fall-blooming asters like ‘Purple Dome,’ or put a fun selection of pumpkins around the base of your grasses for a festive fall display.
