Frost tolerance for peonies:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Since peonies are one of those plants that can tolerate a tiny bit of cold weather you can plant them slightly earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant peonies in Fresno is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant peonies and expect a good harvest is probably September. You probably don't want to wait any later than that or else your peonies may not have a chance to fully mature. If you are starting your peonies indoors then you might be able to get away with starting them a little bit earlier.
