It is likely no surprise to anyone that ornamental grasses are an important part of gardening here in the Flint Hills. Hardiness and fall color are the two qualities prized above many for our grasses.
One of my two nominations for the best ornamental grass for the prairies would be the colorful and graceful Flame Grass, or Miscanthus sinensis 'Purpurascens'. It doesn't seem to be sold much at the nurseries in my area, but I obtained a specimen early on in my garden and I wouldn't trade it for all the grasses I could grow. 'Purpurascens' is only a moderately tall grass for me, reaching about 4 feet in height, and it is not invasive in my garden. It has the good manners to stand upright all year and not sprawl over every other plant in its vicinity as some grasses want to do. In fact, although reportedly hardy from Zones 3-9, it doesn't spread for me anywhere near the l0 feet listed in some descriptions, but stays as a nice 2 foot wide vaselike clump. In the fall, though the picture at the left perhaps doesn't do it justice, it develops a brilliant orange-red coloring that can't be matched by any other hardy grass in my area and that coloring takes a full 2-3 months to fade to brown, even then often returning to a red shade when wet. What also can't be overlooked are the pure white inflorescence's of the bloom, which stand out above that red foliage.
