I planted this rose as a gallon in my Zone 6B(Southern CT) garden this spring, and compared to the 10+ other Buck roses I'm growing, Winter Sunset has, up to this point, not given me a single bit of trouble. It's a fast grower and an eager bloomer(the only Buck rose I have that reblooms as quickly is Silver Shadows), has completely disease-free foliage, and the bugs don't seem to like it very much. It does very well in a spot that gets light shade for part of the day. It would be perfect if it had a stronger fragrance and longer-lasting flowers...on a very hot day, the flowers open completely and shatter in 24 hours!
Does very well in no spray Z9B heat and humidity. It takes a direct hit from a sprinkler and has minimal BS. 4-5wk bloom cycles, moderately vigorous, sparce prickles. Faint scent.
