  • Description

  • Notes

Another wonderful reed grass, Korean reed grass has a looser habit than either 'Karl Foerster' or 'Overdam.' It grows 2 to 4 feet tall and 3 to 4 feet wide. Flower spikes emerge from late summer to early fall, arching up and out, giving the grass a fan-like shape. Flowers emerge green, but pink-up over the summer, and turn wheat-colored in the fall. Flowers are fluffier than on other reed grasses.
Grow in full sun to part shade in nearly any soil, as long as it is well-drained. Cut back in late winter to early spring (see Guides). This species of reed grass needs a bit more water in the hottest summer months.
