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.

By using the USDA zone info for Zone 13a it's a good idea to determine when you can plant iberis.

Planting Calendar for Iberis

Frost tolerance for iberis:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Iberis do well in mild cold which tells us that you can plant them a little earlier in the year than more sensitive plants.

The earliest that you can plant iberis in Zone 13a 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 iberis and expect a good harvest is probably November. If you wait any later than that and your iberis may not have a chance to really do well. If you are starting your iberis indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

In Zone 13a it never frosts. It might get as low as 60°F during the coldest months of winter.

Since the USDA zone info for Zone 13a may not be accurate from year to year the actual date of last frost will vary from year to year. Since it never frosts in Zone 13a you do not have to be ready to cover your iberis in the event of a surprise late frost.
