low growing blue perennials
I have a flower boarder infront of a 6ft garden wall and i am looking for low growing blue perennials. The border gets the early morning sun. On the wall I have a ceanothus and clematis, both doing well. Then at the back a couple of delphiniums, veronica, penstemons, scabious and tradescantia. My meconopsis died. The only low growing ones i have found so far are violas and campanula blue chips. Any other suggestions please.
