A way of estimating when it's possible to plant iberis is to consult the USDA zone info for Auburn.

When to plant:	Up to 5 weeks before last frost.

Iberis can survive in some cold which tells us that you can plant them just a bit earlier in the year than more sensitive plants.

The earliest that you can plant iberis in Auburn is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant iberis and expect a good harvest is probably September. If you wait any later than that and your iberis may not have a chance to fully mature. Starting your iberis indoors is a great way to get them started a few weeks earlier.

Last Frost Date

Since the USDA zone info for Auburn is not always accurate the actual date of last frost can change quite a bit from year to year. Half of the time in Auburn last frost occurs after March 15 so make sure that you are prepared to protect your iberis if you have a late frost.
