One of the first steps you take when you are making a decision about your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

The first opportunity to plant anchusa in Zone 12a can be determined by using the USDA zone info.

Planting Calendar for Anchusa

Anchusa are very cold tolerant which means that you can get them planted much earlier than more sensitive plants.

The last month that you can plant anchusa and expect a good harvest is probably November. Any later than that and your anchusa may not have a chance to fully mature. Starting your anchusa indoors is a great way to get them started a couple of weeks earlier.

It's important to remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 12a and it is different every year. Since it never frosts in Zone 12a you do not have to be ready to protect your anchusa if you have one of those late frosts.
