I certainly agree with the previous post. I live in the Seattle area "black spot and powdery mildew" capitol of the country. This summer has been particulary cold and moist with lots of fog and rain yet White Gold has never shown any signs of disease. Despite the unseasonably cool weather, it continues to pump out these beautiful fragrant white/buff (cloud puff) blooms that smell heavenly. It is a healthy grower with thick shoots and plenty of foliage. Overall a very nice looking plant. It's been in the ground for three years now and I have never had to treat it for disease.
