My garden/landscape is zone 6 (Northern KY). This rose is always blooming. It has darker, almost blackish-green, foliage. The plant is very well-behaved. It gets about 3 feet high by 3 feet wide roughly in my garden. I never had much problem with blackspot. It did sometimes have mildew (rare for that here in my limited experience), but it wasn't very noticeable. The mildew certainly didn't appear to affect the plants blooms. It was planted facing Northwest against the house in clay soil (no amendments). It probably could have benefited from a bit more light, but it still did well. At the time, I was new to gardening (I actually started the rose out on a slope, on the edge of a wood line, where I later learned very little grows due to dry soil/competition with trees). I was forced to move the rose (and several other plants) though. I think the best way to learn is experience though, right?

I grew pink Knock Outs, Julia Child Rose, Livin' Easy and this rose until the winter of 2013-2014. I lost my White Out Rose and Livin' Easy Rose this winter. I had the White Out rose for 4-5 years with no problems until then. This past winter was unusually cold around the U.S. and Kentucky/Cincinnati was no exception. It might benefit from protection in colder zones. I noticed no scent from this rose. It's not a very pretty bloom in comparison with a Julia Child per se. However, for a landscape rose, this is a very nice rose and blooms almost continuously throughout the growing season. The one thing I will note about the blooms is that as it ages, it tends to turn brown before falling off. Again not a huge deal to me, but it might matter to some.
