The last month that you can plant lunaria and expect a good harvest is probably July. You probably don't want to wait any later than that or else your lunaria may not have a chance to really do well. If you are starting your lunaria indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

The average date of last frost is June 15 in Zone 1a. It might get as low as -60°F during the coldest months of winter.

Since the USDA zone info for Zone 1a is not always accurate our actual date of last frost changes from year to year. Since half of the time in Zone 1a it frosts late in the year after June 15 be ready to protect your lunaria in the event of one of those late frosts.
