The Flowers of Summer: Echinacea

We love this native American wildflower as much without its petals as with them. The name comes from the Greek echinos or sea urchin for its spiny center. It's great for adding both texture and a splash of color to arrangements. We've never taken the time to count each individual bristle but we expect, like sunflower seeds, the total would be a Fibonacci number, familiar to fans of The DaVinci Code.
