Peony ‘Festiva Maxima’ is a big frilly pure white double peony splashed with crimson flecks. Its scent is glorious. Mature bushes grow to 3 ft. by 3 ft. Herbaceous peonies are very long-lived perennials. They are so easy to grow that some have been known to survive and flourish over 100 years completely neglected. In our zone, plant in full sun to dappled afternoon shade with the “eyes” (small pink buds) no more than 1-in. beneath the soil. Failure to flower can occur if planted too deeply.
