Beautiful, David! I never knew how pretty tree peony blooms can be until I started haunting this forum a few years ago! How old is your tp? The blooms are gorgeous now; it's going to be a truly impressive specimen quite soon, huh?

Wow, what a beauty! Do you know its name?

That is gorgeous.

Mine are now pretty close to blooming, but one thing I've noticed is some chlorosis on some of the leaves, on just some of my plants. Here's an example.

I might be able to help that out with some epsom salts. I believe that healthy foliage is even more important than the blooms.
