The Scabiosas may have a rather ugly name, but wow, what beautiful flowers! (Butterflies will love them as much as you do.) And once this one gets going, it gives you true blue flowers week after week. They're great in the garden, and also one of the best perennial flowers for cutting--they have long, clean stems that display each flower beautifully in a vase. Sometimes this perennial is called Pincushion Flower.
