Itoh peonies, also known as intersectional peonies, are hybrids between herbaceous and tree peonies, combining the best traits of both. They feature large, long-lasting flowers on sturdy stems that do not require staking. Blooming in late spring to early summer, they offer unique colors not found in traditional peonies, including vibrant yellows and multi-toned varieties. Thriving in full sun to partial shade, they are cold-hardy and resistant to disease, making them a prized addition to perennial gardens.
