Elaine--
I'll have to check the nurseries come spring. I think the big box places probably have Karl Foerster as I have seen it there before but I agree I'd rather get stuff from other nurseries. There is a small one close by that is a mom and pop place on their farm and they have a lot of unusual stuff so I think this is a perfect excuse to go there once it warms up!
Plus maybe I'd better mention my idea to my DH
though he has said before he would like it if I would plant something on the sloping parts so he doesn't have to mow there. I'm just trying to check on the feasibility of such a project (time, money, effort) first.
Looks like I'll have to check into a few options come spring to see what will be the most cost effective and work the best.
