Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Zone 10a you can estimate when it's the best time to plant aurinia by using the USDA zone info.

Planting Calendar for Aurinia

Frost tolerance for aurinia:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Since aurinia are very cold tolerant you can plant them earlier in the year than other plants that might not handle the cold.

The last month that you can plant aurinia and expect a good harvest is probably October. If you wait any later than that and your aurinia may not have a chance to grow to maturity. You can get started a little bit earlier by starting your aurinia indoors.

Half of the time in Zone 10a last frost occurs after January 31 so make sure that you are prepared to cover your aurinia in the event of a late frost.
