My favorite ornamental grass is Panicum virgatum, or switch grass. It's a native grass that is tops for feeding groundfeeders like sparrows, chickadees, titmice and the like, and there has been so much selection work on this species that there is a huge variety to choose from. 'Cloud Nine' for 8-9' flower heights, 'Dewey's Blue' for fantastically sky-blue foliage, and for the longest time 'Shenandoah' was the one for red in the foliage (Most of the well known varieties like 'Hans Hearns' and 'Heavy Metal' do get red in the foliage later in the season, but 'Shenandoah' has the color right through season...)
Recently I was walking the grasses here at the nursery and found a block of panicums with no tag, but the red color was the heaviest, darkest red I'd ever seen in panicum and it wasn't one or two plants; the whole block was a uniform burgundy color. When I called our perennial propagator to inquire, he told me this was a new selection he'd gotten from (TOP SECRET) and he'd been calling it (TOP SECRET), but it really didn't have a name yet. He also said that the color had been solid like that for the whole season and what'd I think?
I think we have a winner here; that's what I think. I will stay informed and let you know when the plant is to be released and the eventual name, but I can't say much more than that for now (legal reasons). Just wanted my peeps here at the forum to be the first to know about a good thing...
