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.

In Sanibel you can figure out when it's a good idea to plant anagallis by reviewing the USDA zone info.

Planting Calendar for Anagallis

Frost tolerance for anagallis:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Since anagallis are barely cold tolerant you can plant them slightly earlier in the year than other frost tender plants.

The earliest that you can plant anagallis in Sanibel 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 anagallis and expect a good harvest is probably September. You probably don't want to wait any later than that or else your anagallis may not have a chance to fully mature. Starting your anagallis indoors is a great way to get them started a few weeks earlier.

Last Frost Date

In Sanibel the average date of last frost happens on January 31. You can expect an average low temperature of 30°F in the coldest months of winter.

It's important to remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Sanibel and it will vary from year to year. Since half of the time in Sanibel there is a last frost after January 31 be ready to cover your anagallis if you have one of those late frosts.
