i transplanted a peony from a neighbors yard (they were moving) last year. the tuber broke into 3 pieces when i was digging it up. i put them where i wanted (close together, but not too close) and all three have produced sprouts...one has 3 shoots that are doing really well (one is a foot tall) the second piece has 2 shoots that are doing okay and the third also has 2 shoots - they're still only a couple inches tall tho...there was a big
weed near it that i dug up, so i think the roots from that were interfering with the peony.
don't know if this will bloom this year - i don't expect it too, but i can still hope!!
they don't like to be moved, and they will live at least 50 years...sometimes longer.
maybe the red ones need a certain soil condition that is missing and that's why they're not blooming?? or it could just be that, since they're fairly recent plantings, they're just not at the point where they will bloom.
i planted bearded iris and they didn't bloom for 3 years...got lots of lovely leaf growth but no blooms. but, BOY, when they DID bloom!!! definitely worth the wait!!
i'd leave the reds where they are...that particular cultivar might just need a longer 'getting situated' timeframe before producing blooms - if you move them now, you'll end up moving the blooming date back even further!!
