One of the best tools that you have as gardeners to help us figure out 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.

By using the USDA zone info for South Hill you should be able to figure out when it's possible to plant liatris.

Planting Calendar for Liatris

Frost tolerance for liatris:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Since liatris do well in cold you can plant them much earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant liatris in South Hill 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 liatris and expect a good harvest is probably September. You probably don't want to wait any later than that or else your liatris may not have a chance to really do well. If you are starting your liatris indoors then you might be able to get away with starting them a few weeks earlier.

The average date of last frost is April 15 in South Hill. You should expect an average low temperature of 5°F in the coldest months of winter.
