¡®Bartzella¡¯ is a prized cultivar that provides an abundance of large, pleasantly fragrant, bright yellow double flowers with a touch of red in the center, that are a joy to behold. The plants are robust growers that stand strong throughout the summer and into fall. An Itoh peony is a cross between a tree peony and an herbaceous garden peony, combining the best qualities of both. Despite their regal, delicate looks, they are easy to grow and very long-lived, providing delights in the garden for years and years.
