One way of figuring out when you can plant anagallis is to use the USDA zone info for Trinity.

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 grow to maturity. Starting your anagallis indoors is a great way to get them started a couple of weeks earlier.
