'Cora Louise' Itoh Hybrid Peony is one of the more vigorous Itoh introductions, bred by Roger Anderson of Wisconsin. It combines excellent hardiness with extremely large showy blooms. The 10" flowers have white petals which are maroon at the base, surrounding the yellow stamens. The form is semi-double and the flower production in May is plentiful. Like all the intersectional Peony hybrids, Paeonia 'Cora Louise' is a wonderful tough addition to the perennial garden.
