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

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

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 slightly earlier in the year than other plants that might not handle the cold.

The earliest that you can plant anagallis in Edinburgh 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 grow to maturity. 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

The average date of last frost is April 15 in Edinburgh. In the coldest months of winter you should expect an average low temperature of -10°F.

Since the USDA zone info for Edinburgh is not always accurate the actual date of last frost can change quite a bit from year to year. Half of the time in Edinburgh it frosts late in the year after April 15 so make sure that you are prepared to protect your anagallis in the event of a late frost.

USDA Zone Info for Edinburgh

Here is the info for USDA Zone 6a.
