Hi!

I need a ground cover for a kind of tricky spot. It is for a bed in my backyard, which is on the west side of my house, so it will pretty much get full sun for most of the day. It's also on a hill, and will receive some foot traffic from our dogs, which use a corner part of the bed to get to our porch (no matter how many times we've tried to train them to go around). I live in Michigan, so it would need to make it through our winters, and the only thing I really plan on keeping in the bed are the 5 lilac bushes that we planted a few years ago. Those have done incredibly well, so I'm hoping to find a ground cover that will be compatible and will showcase our lilac bushes. I'm open to flowering, evergreen, whatever. It's a pretty large area, so something that would spread pretty quickly would be nice.

Thanks for any suggestions!
