peonies change color
In Fall 2006 we transplanted peonies plants (not tree) from a friends yard to our yard and separated into 2 batches. Batch #1 was planted in full sun on south side of house against metal vinyl siding and batch #2 was planted in full sun on west side of house but away from the house. Before Memorial Weekend batch #1 bloomed a pale pink color. Two weeks later batch #2 blooms a deep rich blood red color. Both are planted in the same acid soil. Why did these bloom 2 different colors? They're so pretty and we were so happy they bloomed in the 1st year after being transplanted too. Thanks in advance for your assistance.
