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.

One way of making a decision about when it's possible to plant lysimachia is to examine the USDA zone info for Lake Jackson.

Planting Calendar for Lysimachia

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

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

The earliest that you can plant lysimachia in Lake Jackson 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. You probably don't want to wait any later than that or else your lysimachia may not have a chance to fully mature. You can get started a little bit earlier by starting your lysimachia indoors.
