The last month that you can plant anagallis and expect a good harvest is probably August. If you wait any later than that and your anagallis may not have a chance to fully mature. Starting your anagallis indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

The average date of last frost is May 15 in Zone 3b. You can expect an average low temperature of -35°F in the coldest months of winter.
