Leaves on tree peony have gone pale with white veins, what is wrong with it?

Question

I bought the tree peony a few months ago and it was planted in pot soon after. It was fine until recently. In the photo you can see an aquilegia that seeded itself in the pot.
I hope you can help, as I don’t want to lose it.
I have another tree peony planted in the garden which is about 35 years old, which hasn’t had any problems.

I'm sorry, but your photo did not come through. It sounds as though your plant has a virus of some kind, but without a photo it's just a guess. Here's an article from the University of Connecticut that may help you identify the problem:
