Has anyone planted, and had luck growing this grass in our climate? I am thinking of trying it since I have lots and lots of shade gardens. I love the soft mounded look of it but all the web sites say the hardiness is not Zone4. Supposed to be a new variety "All Gold" that is more winter hardy. I live in Minneapolis and it would be on an east facing slope. Maybe I will buy 1 and see if it comes back next spring. Nothing to lose but money and a tiny bit of Gardener's Hope!
