The USDA Zone info is a great tool for gardeners to help us figure out your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of getting a good idea when it's possible to plant ajuga is to examine the USDA zone info for Zone 10a.

Planting Calendar for Ajuga

When to plant:	Up to 7 weeks before last frost.

Since ajuga are very cold tolerant you can plant them a lot earlier in the year than more sensitive plants.

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

Half of the time in Zone 10a you get surprised by a frost after January 31 so make sure that you are prepared to protect your ajuga if you have a surprise late frost.
