Description
The large, strongly fragrant red and white flowers have a high-centered bloom form and appear continuously throughout the season. They are double, have a diameter of more than 10 cm and up to 30 petals. In the sun, their colour changes from white to carmine red, beginning at the edges. The flowers are very large and usually borne singly, on long, prickly stems. The flowers have a strong, sweet scent. The red color of 'Double Delight' is the product of ultraviolet light on natural pigments in the petals. If the plant is grown in a greenhouse, which blocks ultraviolet light, the petals will be white in color.'Double Delight' is a medium-tall bushy shrub with large, dark green leaves.
