Hostasmore, if you ever become so inclined, you could try hakonechloa grass against a south facing wall in full day or 1/2 day sun. It might be the right micro-climate there.

I've seen a variegated one that looks nice. I will have to look for it sometime for my gardens. Cayuga, your picture looks like a huge plant! I didn't know it would get that big. I'll have to make sure I keep an eye on mine. Mine are all too close to my hosta and heuchera.

My Hakonechloa macra aureola (a variegated Hakone grass) has a tendency to revert to a solid green. Whenever the solid green appears, I dig it up & plant it elsewhere. The solid green still has the graceful motion of its parent plant but is without the 'bright light' effect in the garden. Here is a photo of 2 that I had just transplanted. The Solid green Hakone is (of course) hardier that the variegated one & grows faster too.
