One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

You should be able to determine when it's possible to plant anagallis by using the USDA zone info for Zone 9b.

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 are barely cold tolerant you can plant them just a tiny bit earlier in the year than more sensitive plants.

The earliest that you can plant anagallis in Zone 9b is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant anagallis and expect a good harvest is probably September. If you wait any later than that and your anagallis may not have a chance to really do well. Starting your anagallis indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

On average the last frost has passed is on February 15 in Zone 9b. You can expect an average low temperature of 25°F in the coldest months of winter.

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 Zone 9b and it can change quite a bit from year to year. Since half of the time in Zone 9b there is a last frost after February 15 be ready to protect your anagallis if you have one of those late frosts.
