Mary Stella, that is an absolutely perfect Athena bloom! Did you have many buds on it? And Kansas is gorgeous, Karen (C4K)--I'm envious because the stems for both of my Kansas buds were broken in the bad hail storm we had 2 weeks ago and there was no propping them up. Maybe next year....
Does anyone else think being in the coldest zones peonies can be grown in limits your bud production just as much as being in the warmest? With my elevation I think I'm also 4b like Mary Stella. I've divided peonies and given them away at our Rocky Mountain Gardening Forum plant swaps and have been envious of the number of blooms people who live in Aurora or Highlands Ranch CO get with the roots from my garden! Just the change between 4b and 5 seems to make a huge difference on how they perform. We're typically at least 5 degrees cooler here where we live than where we work in Aurora, just 20 miles away! And the change in elevation means we get frost and snow a bit earlier and keep it a bit later, too.
Karen (Kousa!) the blooms I had on my established peonies were bigger this year then in the past. I applied Azomite last spring and your recommended organic bulb fertilizer this spring, think I saw the difference! Unfortunately I didn't see a corresponding increase in stem strength, think I had more ground huggers this mid-season than in the past. Guess I'll have to resort to staking. I've already purchased tomato cages and started cutting them in half (easier said than done, had to resort to a hack saw) so I can have an experimental frost protection cage ready for those peonies most negatively impacted by weather this spring. I'm wondering if I left clear, heavy plastic covering the tops until the plants were big enough for it to be in the way if it might be a way to semi-protect them from the hail. Or maybe replace the plastic with hardwire cloth after Mother's Day? I don't think I'd want to commit to doing it for many but maybe I'll try it on the 20 or so most impacted plants and see if there is any improvement. And I'll document the process here, of course! Success or failure, it'll start a conversation, anyway!
