Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of determining when to plant lysimachia is to consult the USDA zone info for Winters.

Planting Calendar for Lysimachia

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

Lysimachia are moderately cold tolerant which tells us that you can start planting them earlier than more sensitive plants.

The earliest that you can plant lysimachia in Winters 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. If you wait any later than that and your lysimachia may not have a chance to really do well. You can get started a couple of weeks earlier by starting your lysimachia indoors.

Last Frost Date

In Winters the average date of last frost happens on February 15. It might get as low as 25°F during the coldest months of winter.

Since the USDA zone info for Winters is an average the actual date of last frost is different every year. Half of the time in Winters there is a last frost after February 15 so make sure that you are ready to cover your lysimachia if you have one of those late frosts.
