A photo of Peonys always brings up the old wives tale that ants must be present for a peony to bloom. Not true. Ants just love a good meal, and in prebloom stage, peonies emit a sweet nectar that is ant candy. When they open (the peony,not the ant) the ants go away.
Ants and peonies go together like romance and accordions (ok .. so I am a sick puppy .. sue me)
