Heirloom peonies have been favorites for generations of American gardeners. Many of these old fashioned peonies have been in existence for 100 years or more. We list this group of 'Grandma's' peonies that are at least 80 years old. They are still in fashion and popular today because of their beautiful blossoms, fragrance and their quality performance as cut peony flowers in arrangements. Plant them in any peony garden or sunny landscape to enjoy flowers each spring.
