A way of figuring out when it's a good idea to plant anagallis is to consult the USDA zone info for Monticello.

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 do ok in moderate cold you can plant them a bit earlier in the year than other frost tender plants.

The earliest that you can plant anagallis in Monticello 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. Any later than that and your anagallis may not have a chance to grow to maturity. 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 Monticello. It might get as low as -15°F during the coldest months of winter.

It's important to remember that the actual date of last frost is an average because it is based on the USDA zone info for Monticello and it will vary from year to year. Half of the time in Monticello you get a frost after April 15 so be sure to be ready to cover your anagallis in the event of a late frost.
