Peonies Love Cold Weather

Herbaceous peonies do best in Hardiness Zones 3 to 8 because the winters are cold enough that they encourage buds to form. For peony plants to truly thrive, most varieties require an average winter temperature of 40 degrees. And they are hardy down to minus 50 degrees. Tree peonies are not as hardy.
