I have 2 hydrangeas, 4 years old in the same planter. One is peach color the other is yellow. This spring I had one flower ,only one, that looked like this. Amazing!

Hello, mongerj. Hmm, that doesn't look like a hydrangea bloom. They also do not produce peach /yellow blooms.

Can you post additional pictures of the shrub and close ups of leaves to see if someone can ID the plant. Maybe a double bloom hibiscus or ???

I think @mongerj meant to say Hibiscus ... and what a beautiful Hibiscus bloom that is! Years ago I had Hibiscus (Hibiscus rosa-sinensis 'Double Apricot') that sometimes had yellow shades mixed in with the apricot coloration but I'd love to have one with all the pretty colors like your beauty!

When googling, I found photos on this pinterest page of double hibiscus blooms with some really nice color combinations: https://www.pinterest.com/witc...

Beautiful. That is the kind of flower you could get professionally photographed and sell prints of.
