Korean Reed Grass is adaptable and forgiving late blooming grass. It does well in full sun, half shade and full shade too. Probably the only flowering tall grass suitable for shade.
Award of Garden Merit by Royal Horticultural Society (UK).
3.5-4' tall (with flowers) x 2-3' wide vase-shaped clumps. This is warm season grass (grows to it's full height in warm part of the year), so it's blooming very late in September till November.
Newly emerged flowers are pinkish and later fade into tan color and in the late fall into straw-brown color.
Grows well from full sun to shade and tolerates even drier shade (in shade expect fewer flowers though). Average garden soil, clay, loam, moderately fertile or fertile, with medium (average) moisture to medium-dry.
Hardy in zones 4 to 9. Deer and rabbit resistant. Heat and humidity tolerant. Attracts small birds.
It's native to central and eastern Asia.
Can be combined with many common taller perennials.
Established plants do seed some around, but not invasively. Although there is one annoying fact about this grass - if you have another grasses around, it may seed into clump of the other grass and you will not notice small seedling, and you'll notice when the father grass gets bigger and starts blooming. Than it's impossible to pull the seedling out (especially if it seeds into taller grasses like Panicum - Switchgrass or even into some wider and dense clump of perennial). To prevent seeding, you can cut the flowers back in November.
