Tree peonies are hardy, long-lived, woody shrubs that don't die back to the ground in the fall like bush peonies. Our tree peonies are grafted (a technique whereby the bud of the desired variety is fused onto understock and imported directly from Japan. Grafted plants tend to establish more quickly and are able to withstand adverse soil conditions more easily than tree peonies that grow on their own roots. Tree peonies flower just before herbaceous varieties, and are suited for zones 4-7. Check out all our tree peonies for sale.
