Linda, the advice to not plant peonies where one has grown before is not consistent. I've seen plenty of instructions on dividing that says to replant part back in the original spot! Especially if you amend your soil and fertilize I don't think that is a biggie, I've always done it with no issues. I think what you need to find out is why the 2 didn't grow. Were those different from the others? I've had crappy luck with a couple of varieties--I've bought Nick Shaylor 3 times now and have yet to see it even start growing.....might trade for that one in the future but am not going to spend money on it again. Did you get a couple of finicky hybrids in amongst a bunch of easy to grow lactifloras? I wouldn't rule out planting another peony in the same place but would certainly do all I could to understand why those didn't grow first. I'd start as Diann suggested and dig those roots out and examine them, AFTER they've had enough time to show growth if they were going to this spring, of course.
