Strong stems support large, creamy white, double blooms with frothy petals, creating quite a showpiece in mid to late spring. Glossy, deep green foliage is attractive and ornamental throughout the growing season. New growth emerges burgundy in spring and turns a soft yellow in fall. Growing 24-30" tall with a 24-36" spread, this garden classic is ideal as a small hedge, clustered with other peonies or as a specimen plant. Plant in full sun to partial shade. Deer resistant. 2-3 eye bareroot. Zones 3-8. Paeonia 'Duchess de Nemours' Peonies have few requirements: give them a sunny well-drained location, plant 2-4' apart, with the eyes (new buds at the crown) no more than 2" below soil level and apply fertilizer or compost in spring. They take a while to establish, often 3 years before the first bloom—but the wait is worth it. They are heirloom quality. Let them grow undisturbed and they will bring joy to you and your loved ones through the decades.
