The last month that you can plant lunaria and expect a good harvest is probably October. You probably don't want to wait any later than that or else your lunaria may not have a chance to really do well. Starting your lunaria indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Zone 9b the average date of last frost happens on February 15. We can expect an average low temperature of 25°F in the coldest months of winter.

Always keep in mind that our actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 9b and it can change quite a bit from year to year. Since half of the time in Zone 9b last frost occurs after February 15 be ready to cover your lunaria in the event of a surprise late frost.
