(Ptilotus exaltatus) This frost-tender perennial (hardy in zones 10-12) is usually grown as an annual. It is a stunning wildflower of Central Australia and extremely heat and drought tolerant. Locally named Mulla Mulla, these elegant champagne- to salmon-colored blooms have a bottle brush shape and gracefully dance in the wind. This variety is specifically selected for long, strong stems, making it a perfect fix for cut flower production. These 24- to 30-inch plants are excellent for mixed beds, borders, and containers.
