Itoh peonies are created by crossing herbaceous (regular garden) peonies with tree peonies; the result is larger flowers on stronger stems that don't attract ants, on plants that are reliably hardy.
Large, semi-double, apricot-yellow flowers, heavily blushed and marked copper-pink, in early summer.
Dense, bushy habit; an incredible cut flower.
Does not require support.
Fertile, moist, well-drained soil. Sun to light shade.
