One way of determining when to plant anagallis is to consult the USDA zone info for Irving.

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 Irving 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. If you wait any later than that and your anagallis may not have a chance to fully mature. If you are starting your anagallis indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

In Irving the average date of last frost happens on March 15. In the coldest months of winter you should expect an average low temperature of 10°F.

Always keep in mind that the actual date of last frost is just an average because it is based on the USDA zone info for Irving and it is different every year. Since half of the time in Irving it frosts late in the year after March 15 be ready to protect your anagallis in the event of a surprise late frost.
