The last month that you can plant cuphea and expect a good harvest is probably September. Any later than that and your cuphea may not have a chance to really do well. Starting your cuphea indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

On average the last frost when the weather gets warmer is on January 31 in Zone 10a. We should expect an average low temperature of 30°F in the coldest months of winter.

Since the USDA zone info for Zone 10a is not always accurate our actual date of last frost changes from year to year. Since half of the time in Zone 10a we get a frost after January 31 be ready to cover your cuphea if we have a late frost.
