One of the first steps you take when you are getting a good idea your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Zone 9a you can figure out when it's the best time to plant lunaria by using the USDA zone info.

Planting Calendar for Lunaria

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

Since lunaria do well in moderate cold you can plant them a little earlier in the year than other frost tender plants.

The earliest that you can plant lunaria in Zone 9a 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 lunaria and expect a good harvest is probably October. If you wait any later than that and your lunaria may not have a chance to grow to maturity. If you are starting your lunaria indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

The average date of last frost is February 15 in Zone 9a. It might get as low as 20°F during the coldest months of winter.

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