One of the best tools that you have as gardeners to help us determine 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.

The earliest that you can plant anagallis in Zone 5b can be determined by using the USDA zone info.

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 tend to make it in a tiny bit of cold which tells us that 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 5b 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. Starting your anagallis indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Zone 5b the average date of last frost happens on April 15. You should expect an average low temperature of -15°F in the coldest months of winter.

Since the USDA zone info for Zone 5b is not always accurate the actual date of last frost will vary from year to year. Half of the time in Zone 5b you get a frost after April 15 so make sure that you are ready to protect your anagallis in the event of a surprise late frost.
