Calamagrostis x acutiflora 'Karl Foerster' Feather Reed Grass is one of the world's most popular ornamental grasses, named the 2001 Perennial Plant of the Year. This upright, clump-forming cool-season grass produces narrow bright green foliage that forms a slightly arching base, topped with dramatic red-bronze feathery flower spikes from early to midsummer that mature to a golden shade and persist through winter. Sold by Alder & Oak as a 2-pack in 3.24-gallon containers with plants that are 2-3 years old at shipping.

The foliage grows 2-3 feet tall and wide, while the flower spikes extend the total height to 4-6 feet, creating a striking vertical accent in the landscape. Hardy in USDA Zones 4-9, this grass thrives in full sun to part sun and requires regular watering, with more frequent watering in extreme heat. It is heat tolerant, easy to care for, and does not require deadheading. Karl Foerster is well suited for use as a border plant, screening, erosion control, mass planting, or cutting garden. The feathery plumes attract birds and work beautifully as both fresh and dried cut flowers. Prune back to one-third of the plant in very early spring before new growth begins. Not for human or animal consumption. Does not ship to AL, AR, FL, ID, LA, MI, MS, NC, SC, TN, TX, OR, WV, AK, HI, or PR.
