Anderson R.F. (1986) Cora Louise is a semi-double to double Itoh Hybrid with beautiful unique white flowers and a purple heart. With the soft lime-scented, up to 20 cm, large flowers, a must for gardens and parks. Cora Louise flowers easily and is rich in flowers that protrude well above the plant with dark leaves. In the mid-late season a beautiful plant for solitary and group planting. Cora Louise retains great ornamental value even after flowering. The leaves remain green until frost and turn to autumn shades in the autumn. Cora Louise has enormous vigor, but it does take a number of years to become a mature plant.
