I bought this peony from a local nursery. Generic. Red. I also bought three others. Generic. Pink. I bought generic(there's no name as to what the variety is) because I'm going to try and winter them over in pots and see how that goes. The red peony's leaves are turning colour. There are some spots on it but I put that down to the fact that it was in shade at the nursery and I suddenly put it into full strong sun on my patio. Maybe it burnt the leaves. No increase in spots or increase in the size of them. I was just wondering if there was any plant disease that is occurring. I tried to look it up, however, for all the information on diseases that affect peonies, what I am seeing on this peony doesn't match any of them.

Its most likely sun scald from the transition to full sun. This is a time when some shade is a good thing!

Thank you. That's why I thought but I wanted to be sure. I guess I went too literally with hearing that they love the sun so I intended to give them lots of it.

Janyss, please be careful when you expose those black plastic pots to the sun. In our temperature zone, the black plastic pots get really hot to the point that the roots may be damaged.
