I am beginning to think that 'Rita Jane' shows here dislike of our very wet spring, by making warty/raised places on her leaves. That must be why all of that disappears once the weather dries out and warms up.
It also looks like the slugs might be lightly feeding on yours Connie. I was having a lot of marks on different ones during our wet months, Kevin helped me figure out what the problem was. I started putting Slugo bait out, the one approved around pets and children, in the fall, once in Jan, and again in Feb & March. No more spots on the semps leaves.
Here she is in May in my garden. You can see she is getting healthier/happier by May.
