My neighbor has one that she brought with her from Alaska, which is how I became acquainted with them. So I know they'll grow in this area, but the only places I have to plant things where the dogs or goats won't destroy them aren't quite suitable. We do have one area that we're thinking about reworking, and DH was talking about fencing that area off, so it may be a possibility.
It sounds like you're concerned about them breaking ground too soon? What about just covering them with some straw? Or would that get too soggy?
