The USDA Zone info is a great tool for gardeners to help us estimate your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Medford you can estimate when it's a good idea to plant lunaria by referring to the USDA zone info.

Planting Calendar for Lunaria

When to plant:	Up to 5 weeks before last frost.

Lunaria are moderately cold tolerant which tells us that you can plant them earlier than more sensitive plants.

The earliest that you can plant lunaria in Medford 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.
