I have a question about my brunnera. It was fine until the last month or so, the leaves have developed a dark splotchy discoloration on the leaves. The same thing occurred last summer. What is it and what can I do to prevent it?
I live in Southern Indiana. Thanks.

Mine will do that too in summer. If it's the same thing, more shade and more water might help.

Thank you @IrisLilli for responding to this question! I don't know how I missed it! My apologies @jacobi008 for not responding!!
