It repels deer as well.
Herb Robert is a plant that I allow to grow in my yard in a controlled area. Not everyone loves the plant but I think it is very pretty. Each gardener must decide which items are 'plants' and which are 'weeds' unless there are laws that make that decision for us. I know you'll do a great job on that space.
Look forward to seeing photos as you progress.
I like the bench; that was a great find!
