If you’re looking for an ornamental grass that delivers fall interest, check out Korean feather reed grass (Calamagrostis brachytricha). Large, foot-long seedhead plumes soar above leaves in late summer, donning a pink tinge that matures to tan. Seedheads dry well and make a nice addition to dried arrangements, or let them age naturally in the garden where they’ll add interest all winter long. Korean feather reed grass likes moist soil and tolerates heavy clay soil. Cut plants to the ground in early spring. Leaves grow 36 inches tall and 20 to 24 inches wide. Seedheads stand 12 inches above leaves. Hardy in Zones 4-9.
