Love love LOOOOOOOVE this one. It was an impulse addition to my order from Floyd Cove last year (lacking self control I know...
) and I could not be happier. Went through 3 rounds of scapes last year and is starting to put up a rebloom scape now but I'm going to cut it so that it will put the energy into multiplying. I haven't measured but the blooms tend to be in the 5-6 inch range for me. Unfortunately I don't know about the hardiness since I overwintered it indoors last year. It has tended to be on the resistant side but not extremely resistant to rust. Last year I had a couple new plans come up from Florida that were absolute rust buckets and SI fared much better.
I've found it to be pod and pollen fertile. I did not have trouble setting pods on it but my expectations may be lower than in southern states. The pollen tends to be very pale yellow and at first glance would make me think it was bad, but I've had little trouble using it.
