Appeal: Duchesse de Nemours Peony is a lovely choice to add to your perennial garden beds. It will have large white double flower blooms in late spring to summer. The flowers open up on top of the long stems near the top of the foliage and are fragrant. The foliage is glossy dark green and forms a shrubby mound. Once the flowers fade the foliage remains to fill space in your garden. Deer resistant.
