The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

A common way of determining when it's a good idea to plant artemesia is to consult the USDA zone info for Zone 12b.

Planting Calendar for Artemesia

Frost tolerance for artemesia:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Since artemesia are one of those plants that can tolerate a tiny bit of cold weather 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 artemesia in Zone 12b 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 artemesia and expect a good harvest is probably November. You probably don't want to wait any later than that or else your artemesia may not have a chance to fully mature. If you are starting your artemesia indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

In Zone 12b it never frosts. In the coldest months of winter you should expect an average low temperature of 55°F.

Just be sure to remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 12b and it changes from year to year. Since it never frosts in Zone 12b you do not have to be ready to cover your artemesia in the event of a surprise late frost.
