This rose is being sold under the name Chateau Merlot in the big box stores. It had powdery mildew the first year I planted it. The next year there was none, but it did get some black spot, though not too bad versus some of the plants near by. My Iceberg, just 6 feet away, dropped all it's leaves after a heavey rain from BS.

The flowers on my plant were single to semi double and were a striking dark red. The plant still hasn't gotten very big just 18" high x 18" wide. It was hardy to the snow cover here in Zone 4
