Anagallis are one of those plants that can tolerate a tiny bit of cold weather which means that you can plant them slightly earlier than other plants that might not handle the cold.

The earliest that you can plant anagallis in Hampshire 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 really do well. If you are starting your anagallis indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

The average date of last frost is April 15 in Hampshire. It might get as low as -15°F during the coldest months of winter.

Just be sure to remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Hampshire and it changes from year to year. Since half of the time in Hampshire you get a frost after April 15 be ready to cover your anagallis if you have a surprise late frost.
