Whatever you don't, DON'T PLANT BLUEBEARDS. Found that one out the hard way. Same with SilverMound. They'll take over EVERYTHING. How about some nice mums? Would those do OK in your area? I'm putting in daylilies & mums between my roses so that I have greenery all the time (well, not in the winter of course). Blue Butterflies Delphiniums are another one that I'm really loving, plus, of course, agastaches...
