One of the first steps you take when you are figuring out your gardening schedule is find your USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

A common way of determining when it's a good idea to plant lysimachia is to examine the USDA zone info for Winter Garden.

Planting Calendar for Lysimachia

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

Since lysimachia do well in moderate cold you can plant them a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant lysimachia in Winter Garden is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant lysimachia and expect a good harvest is probably October. Any later than that and your lysimachia may not have a chance to really do well. You can get started a few weeks earlier by starting your lysimachia indoors.

Last Frost Date
