Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of getting a good idea when to plant lysimachia is to refer to the USDA zone info for Newport.

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 moderately cold tolerant you can plant them a bit earlier in the year than more sensitive plants.

The earliest that you can plant lysimachia in Newport is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant lysimachia and expect a good harvest is probably August. Any later than that and your lysimachia may not have a chance to fully mature. You can get started a couple of weeks earlier by starting your lysimachia indoors.

Last Frost Date

On average the last frost is on May 15 in Newport. You should expect an average low temperature of -30°F in the coldest months of winter.

Just be sure to remember that the actual date of last frost is an average because it is based on the USDA zone info for Newport and it can change quite a bit from year to year. Half of the time in Newport you get surprised by a frost after May 15 so just be sure to be ready to cover your lysimachia if you have a late frost.
