Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Chelsea you can estimate when to plant lunaria by checking out 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.

Lunaria tend to make it in mild cold which means that you can plant them just a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant lunaria in Chelsea 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 lunaria and expect a good harvest is probably September. Any later than that and your lunaria may not have a chance to fully mature. If you are starting your lunaria indoors then you might be able to get away with starting them a couple of weeks earlier.
