The USDA Zone info is a great tool for gardeners to help us figure out your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Woodland you can determine when it's the best time to plant liatris by checking out the USDA zone info.

Liatris are one of those plants that can tolerate quite a bit of cold weather which means that you can start planting them much earlier than other plants that might not handle the cold.

The last month that you can plant liatris and expect a good harvest is probably October. Any later than that and your liatris may not have a chance to fully mature. Starting your liatris indoors is a great way to get them started a few weeks earlier.
