Where to grow: Peonies thrive in cooler climates (Sunset zones 1–11; A1–A3), where they get pronounced winter chill. But some (see below) will grow well in warmer climates. All are also worth a try in dappled shade in zones 14–20. There, give plants afternoon shade Read more
Peonies go through the same life cycle each year. This cycle consists of three phases: plant growth, flower growth and the rest phase. During the rest phase, the part of the plant above the soil dies. The rest phase takes place in Autumn.

What is peony wilt caused by? Peony wilt is caused by the fungus Botrytis paeoniae, which is closely related to Botrytis cinerea that causes grey mould on other plants. It produces small, black resting structures (sclerotia), which fall to the ground in affected plant material.
Many varieties can even survive a zone 2 winter (that's a low of -50 degrees F). If a peony is well situated and happy, it may bloom for 100 years or more with little or no attention.
