Generations of gardeners have loved peonies for their big, fluffy and fragrant flowers that bloom in late spring. They're a favorite perennial for enjoying in the garden and in cut flower displays. They're also prized for their foliage that remains attractive throughout the growing season. These sun-loving perennials can be planted in mixed perennial beds, as a small hedge or to line a walkway. Peonies are some of the longest-lived perennials with some living for more than 100 years. The Itoh peony, a cross between a tree peony and bush peony, is growing in popularity because it delivers the best of both worlds. They have the sturdy stems of a tree peony and the large flowers of a bush peony. Peonies can be grown in full sun or partial shade.
