I bought two of The Wright Brothers roses as own-root plants. They grew quite vigorously and the blooms held their form even with a lower petal count. Both plants overwintered very easily with little cane dieback suffered at all until The Big Easter Freeze hit. Though both of my bushes survived, all the original new growth in spring 2007 was killedk and it is spending all it's energy healing now instead of blooming and growing very tall this year. Otherwise, health and disease resistance has been excellent as well. the growth is very upright. This is a good rose and look forwar to more "normal" growing years so it can show it's real stuff.
UPDATE 11/2009--Now that I have grown these two rosebushes three full years, I feel I can make some more comments about it. So far the bush has proven to be healthy, vigorous, winter hardy, and not affected by heat and humidity to any significant degree. It will develop Powdery Mildew if not sprayed reglularly in the cooler and more humid weather of Fall. It can get very severe if no treated. Blackspot doesn't seem to be an issue. This bush gets relatively tall at between 6' and 8' tall with lots of canes and lateral growth to support it's heavy blooming. Insects seem to leave this roses' blooms which are large, medium pink, well formed for exhibition, long lasting with good substance, but basically scentless. If you spray I would highly recommend this rose, but it does need protection from PM in the Fall.
