One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

A common way of estimating when it's the best time to plant anagallis is to refer to the USDA zone info for Honolulu.

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 do well in some cold which means that you can plant them a bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant anagallis in Honolulu is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant anagallis and expect a good harvest is probably November. 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 few weeks earlier.

Last Frost Date

In Honolulu it never frosts. It might get as low as 50°F during the coldest months of winter.

Just be sure to remember that USDA zone info for Honolulu is just an average and the actual date of last frost can change quite a bit from year to year. Since it never frosts in Honolulu you do not have to be ready to protect your anagallis in the event of a surprise late frost.
