Peonies are a classic ingredient of the perennial border, and have been in cultivation for over 2,000 years. They are beloved for their abundant blooms, the beauty of their exquisite flowers, their delightful fragrance and their bold, lush foliage. Peonies require little more than sun and well-drained soil. Virtually carefree once established, peonies live for generations, are deer resistant, and produce some of the best cut flowers.
