Karl Foerster Feather Reed Grass
Calamagrostis × acutiflora 'Karl Foerster'
Summary
Karl Foerster feather reed grass proved itself a tough and beautiful ornamental whose only drawback is the downtime after cutting back typical of ornamental grasses. It also proved irresistible to rabbits in two sites, Orange and Ventura Counties. Size, flowering, and overall appearance increased incrementally with increased irrigation, but it must be noted that even at the lowest irrigation level, the average plant quality was still rated consistently above the acceptable or very good rating while receiving water only in July and September. By October, the statistical difference in size between treatments had gradually disappeared with each successive irrigation application. For this reason, this plant could be grown successfully on any of these levels of irrigation.
