I won't even attempt to ID your beautiful Peony...too many colors, types, etc. to wade through. Check out the website linked below and I bet you can find your plant. Its an excellent Peony resource. Rosie Here is a link that might be useful: Peony List

Bowl of Beauty. A faithful heirloom peony. Here is a link that might be useful: Bowl of Beauty

@Garcanad: Those blooms look right. Maybe the lavender color is almost undetectable except next to a pure white bloom. Unless someone can find another giant hosta with the same leaf pattern that was released before 2002, I'm feeling pretty confident that it's Earth Angel. As for the green one, some blooms should open soon. I will post new pictures and see if that narrows it down.

Hi Hyed, The are 4' tall and my take lines up with gardengal, that they are likely 'Sister Theresa'. Both Mallet and Dirr describe the aging flowers in a way that best matches with 'Sister Theresa': -Mallet says it keeps its flowers until first frost and that they turn sea green in autumn (this lines up with the color of the flowers where the sun doesn't hit them). Mallet was writing from Normandy, France, so may not color well there, but we have the same green in the shade. -Dirr says flowers become green tinted red when ready to dry and this lines up closer to what I saw at my mother in law’s. Thankfully there aren’t that many white H. macrophylla mopheads that would have been around 20 years ago and in reading the descriptions of, for instance, ‘Le Cygne’, ‘Mme. Emile Mouillere’, ‘Regula’, ‘Schwan’, ‘Woodworth White’, I’m certain it’s none of those, so when I start second guessing ‘Sister Theresa’, I go through the process of elimination again and arrive right back at ‘Sister Theresa’. Phew. Hydrangea detective work is fun and stressful! Thanks for everyone’s input!
