Well, I haven't been very good to it, but it persists in putting out blooms. It is currently growing in just a one gallon pot in the shade of a huge pepper tree, which means it gets almost no light, but persists in blooming nevertheless. I can't tell you about disease resistance, since I am a heavy sprayer. I'll bet it will be good when I find it a more permanent home, but it looks like I am going to move again, so I am putting off putting it in the ground for now.
