Fix leaking sprinklers, valves, and pipes.

  • Description

  • Notes

Karl Foerster feather reed grass is a garden favorite, and for good reason. Its green, fine-textured foliage is gently arching and grows to about 2 feet tall and wide. Oat-like plumes stand very erect over the foliage, growing as tall as 5 to 6 feet. Plumes open whiteish green, later turning a dusky rose, and then tawny colored by winter. Blooms early summer with the plumes lasting into autumn. Holds its presence well into winter. Excellent in mixed perennial or shrub borders, or massed.
Grow in well drained soil, in full sun to part shade. Is tolerant of many soil types, as long as they are not damp or moist. Cut back to inches above ground in late winter to early spring, before new growth emerges. Makes an excellent cut flower.
