Kashmir is absolutely the most disease resistant (modern) rose in my garden (I'm looking at you, KO). I love Ping Lim's roses in general, but this one is a real prize. Mine is own-root, bought potted from a big-box store. This is its second year here in my east Tennessee Z7a garden, and it has proven that last year's health was not a fluke: it's spotless. The bloom is a pure, true red with a velvety finish to the petals, and the bloom form is MUCH more full and graceful than the ubiquitous Red Knock Out, not to mention the color being less strident. I haven't tried them as cut flowers, since they do have short stems. The flowers self-clean, though are sometimes a bit slower to drop petals than I'd like. But a slight shake of the bush, or even a spray with the water hose (!!!!) will clean the whole plant. It's that healthy, that I don't worry at all about water on the leaves. It's almost continuously blooming, with at least one or two blooms at all times, in between major flushes that come every five to six weeks. I'll have to pay attention to keeping this one well fed.
It does send out the occasional octopus cane, but doesn't mind a summer pruning at all. It just reacts by sending out multiple laterals below the cut. This year the bush is about 3'x3', full and rounded, clothed to the ground in shiny green leaves. I suspect from the long canes it has thrown that it will eventually be a much larger rose, possibly 5'x5'.
I grow about 70+ modern roses and 120 teas and OGRs. I bought Kashmir as a landscape "filler", but it's already become one of my favorites. You can't beat "easy and beautiful".

Blooms in flushes and completely healthy in my humid mid Atlantic Maryland zone 7 garden.

Bought Kashmir from RoseFire, Ltd of Ohio three years ago and planted it in my Norfolk, Virginia (8a) front yard where it gets good sun but has received no spraying and no water but rain and the yard sprinkler. I have been amazed at its good health and prolific, beautiful red blooms. This is not an ARS award winner, but it is a magnificent bloomer and pleaser for everyone on my street; and it does it all on its own. Obviously, RoseFire sent me a great rose, but I never would have expected such carefree health and beauty as what this rose has provided. The bush is about 4+ feet tall and 4 feet around, and it responds well to deadheading and pruning to shape the bush. If you want good, healthy plant that blooms quite frequently and can thrive without fungicides, pesticides, or insecticides in a hot summer/relatively mild winter, then Kashmir is a great choice for a bedding plant to provide beautiful color.

According to David Zlasak, Kashmir is triploid.
