One of the best tools that you have as gardeners to help us figure out your gardening schedule is the 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.

The first opportunity to plant lysimachia in Zone 8a can be determined 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 do well in moderate cold which tells us that 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 Zone 8a 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. You probably don't want to wait any later than that or else 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

On average the last frost when the weather gets warmer is on March 15 in Zone 8a. In the coldest months of winter you should expect an average low temperature of 10°F.

Remember that the actual date of last frost is an average because it is based on the USDA zone info for Zone 8a and it changes from year to year. Half of the time in Zone 8a you get a frost after March 15 so just be sure to be ready to protect your lysimachia if you have one of those late frosts.
