ok -- I got mine from the J & P test panel collection 2008. It's still in a 10 gallon pot, but seems to top out at around 5 feet. I spray, so I can't say anything about disease resistance, except that, with spraying I haven't seen any mildew on it. I was disappointed in the blooms the first year I had the plant because they were very small. It grew out of that habit, and the blooms now are around 4.5 inches -- normal size. It grows similar to a grandiflora in habit -- clusters above long basal canes and I would call it a vigorous grower. Frangrance is good -- sweet honeysuckle, I would say. The blooms do last a few days in a vase. Oops wait a minute -- need to move this photo -- just noticed I posted it in the wrong place -- my rose is Peppermint Splash, not Swirl. So sorry. Can you move it?
