One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Clemson you can figure out when to plant lunaria by looking at 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 are moderately cold tolerant which means that you can start planting them earlier than other plants that might not handle the cold.

The earliest that you can plant lunaria in Clemson 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 grow to maturity. If you are starting your lunaria indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date
