Q.disease
Hello. I had these growing in my garden — lots off them — but did not plant them. However, I pulled them out but left a few to see what if anything they were; looks like forget me nots , but has something on the leaves. Can you advise what this could be, and how I could get rid off problem please.
Thank you
Rosalind

From the image it may be infected with Powdery Mildew.
