Common Nature

Nine years ago I transplanted two peonies from my front yard, where the tree had clearly expanded its canopy, into my backyard.

Shade generally only reduces the flowers, but the buds being set too low in the ground will stymie them. You might want to get to know the neighbors and see if they know if they've bloomed in the past.

(I'm suspecting that you are much more southernly than I am.)
