One of the first steps you take when you are determining your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Rochester you can estimate when it's possible to plant lysimachia by reviewing the USDA zone info.

Planting Calendar for Lysimachia

Frost tolerance for lysimachia:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Lysimachia tend to make it in some cold which tells us that you can plant them just a bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant lysimachia in Rochester 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 lysimachia and expect a good harvest is probably September. Any later than that and your lysimachia may not have a chance to fully mature. Starting your lysimachia indoors is a great way to get them started a few weeks earlier.
