PERENNIAL - Pincushion Flower Pincushion flower, or scabiosa, serves up dainty blue flowers all summer and into fall, making it one of the longest-lasting bloomers in the perennial bed. It likes sun or partial shade, and is best at the front of the bed. The foot-tall variety 'Blue Butterfly' stands up to heat best.

I agree, they sound perfect for my deck..... so pretty!
