Molinia caerulea ssp. arundinacea 'Sky Racer'
(Tall purple moor grass)
'Skyracer' grows to about 3 feet wide and 2 to 3 feet wide, and in late summer to early fall, sends up delicate panicles to a height of 6 or 7 feet. This finely-textured ornamental grass is great for areas where you need height but don't have space for a wider, heavier plant. It works well in a sunny border but make sure you site it so you can see it closeup. Expect outstanding yellow color in fall.
