Garden Plants for Flower Arrangements: Rosa ‘Blanc Double de Coubert’

Rosa-Blanc-Double-de-CoubertThis rugosa rose is hardy, healthy and vigorous, and blooms almost continuously. Its pure white flowers have ten to twenty petals and are 3.5 inches across. They have a strong rich fragrance and are followed by fat orange hips. Unfortunately the flowers spoil in the rain. Prickly stems carry dark green pleated leaves that turn clear soft yellow in the fall. The flowers last well in the vase but it is the leaves that are of special interest for flower arranging. If branches are cut as soon as the leaves turn yellow they will last a long time in the vase and make a bright addition to fall arrangements. A delay in cutting results in leaf fall. Hips are valuable in fall arrangements and flowers dry well for winter arrangements.
