Intersectional Peonies, also known as Itoh peonies in honor of Toichi Itoh, are a relatively new peony hybrid.They are created by crossing a tree peony with an herbaceous peony. These peonies produce tree peony flowers and leaves on plants that behave like herbaceous peonies – dying down to the ground in fall and emerging each spring. When mature, these plants create large flowers on a sturdy stem that does not require support. ITOH peonies extend the blooming season, as they reach peak bloom near the end of the herbaceous peony bloom. Each plant can remain in bloom for 2-3 weeks as new side buds continue to open over this period. They come in a wide variety of colors that are not widely available in herbaceous peonies, including an array ofblended colors, pastels, yellows and golds.These colors are more indicative of tree peonies.
ITOH peonies grow to approximately 2-3 feet tall by about 3 feet wide. Their compact form is well suited to the front of the perennial border, as they produce leaves and flowers that cover an entire plant. Large flower size, ease of growing, disease-resistance (especiallyto botrytis), resistant to many insect pests, as well as deer and rabbits, makes them the ideal choice for your perennial border. These plants are not fertile and therefore will not produce viable seeds. The spent blooms can be cut to clean up the plant look and to provide more energy to the next year’s plant.
