blue garden flowers, roses and busy little bees

the cool thing about having perennials in your garden is being surprised when they come back even prettier than they were the year before. these two bees were actually so tiny I barely noticed them at first. the macro makes them appear so much bigger in this close up. does anyone know what the purpley blue flower is? I've only had them a couple of years and the name escapes me!
