Having spent 25 years living in Belgium and seen the price of bare root roses direct from DA I decided to reduce the risk and ordered all of mine form a rose specialist in the Ardennes who sells them potted up. I assumed, correctly, that any he sold would be hardy enough for a Belgian winter. Even so, for their first year I would pot them on and take them under shelter for winter before planting out in the borders.
The only ones I had problems with were early bare root purchases direct from DA - William Shakespeare and Grace turned out to be wussy in winter. WS struggled and Grace just gave up and died.
They advertise their roses as disease resistant If you grow them well, they'll be fine but if you plant them in poor soil already infected with black spot spores you're inviting trouble.
