Before planting it is a good idea to find your USDA Zone info to figure out 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.

The USDA zone info for Dover should be looked at to estimate when to plant anagallis.

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.

Anagallis are barely cold tolerant which tells us that you can plant them slightly earlier than other frost tender plants.

The earliest that you can plant anagallis in Dover 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 anagallis and expect a good harvest is probably August. 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 little bit earlier.

Last Frost Date

The average date of last frost is April 15 in Dover. You can expect an average low temperature of -10°F in the coldest months of winter.

Half of the time in Dover you get a frost after April 15 so just be sure to be ready to protect your anagallis in the event of one of those late frosts.
