MOVE THEM!!! Just the fact you are agonizing over it shows you will wish you had moved them, if you don't. And tell hubby what it will cost to re-create the collection at retail; he'll change his mind. Is he bringing his power tools, or fishing gear, etc? Or is he leaving that stuff behind for the buyer of the house? From a former RE agent, when you list the house, specify on the listing sheet that you are taking most/all of the hostas. When you do dig them, leave divisions of the commoner varieties; don't strip the yard--unless your buyer happens to be another hosta freak. People who don't know or care about plants or hostas won't care that you take yours--people who do know & care will understand why you are moving them with you---if you get that kind of buyer for the house, offer to leave some behind, or divide them etc. Don't forget to also take anything of sentimental value, such as your mother's peonies or whatever. If the buyers don't care about that stuff, you also can always dig it up & give to your local friends, something to remember you by. As to the logistics of the move--contact the hosta club down where you are moving--I'd bet the locals would be happy to "board" your babies in their yards, in plastic bags, distant from theirs (to avoid possibble disease spread) for a few weeks. You'll just have to go up & down a few times. When we moved to this house, the owner was happy to let us start bring pots & plastic bags of plants over, several weeks in advance of our move (and the closing)--I put them under the spruce tree & came over to water them every now & then. Maybe the owner of your new home will let you do the same.

I might be wrong about this, but I think the goal with overwintering potted hostas is to keep them out of the sun. So I would put the pots in a shaded location. Colder and darker is better I think. Plastic pots that won't break. I had several on the screened porch last year (NNE facing). That kept them dry, and they were shaded. And I've overwintered in the unheated garage. I'll have pots in both locations this year because I just didn't get around to planting them in the summer. C'est la vie - I'm only human. But wet newspaper and plastic bags would be great if you're indeed going to have them out of the ground short-term - like if you can dig them up, transport them to the new home, and stick 'em in the ground fairly quickly. (Or - if you want to throw them on the driveway for a while!)

I do like accent walls, and I have such in my current home - I put them there and remain satisfied because I'm trying to please me, not a decorator. But I think the room as shown is too small for an accent wall to work well. But in any case, we need to see all four walls to work with you. It may be hard to get extra photos at this time since the tenants still live there, however.

This might help if you are wondering about size or shape. Keep in mind there are always exceptions to the rules. From the Trelor site.
