A way of figuring out when to plant liatris is to consult the USDA zone info for Corning.

Planting Calendar for Liatris

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

Liatris can survive in a bit of cold which means that you can plant them quite a bit earlier in the year than other frost tender plants.

The earliest that you can plant liatris in Corning is January. However, you really should wait until February if you don't want to take any chances.

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 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.

Last Frost Date

The average date of last frost is February 15 in Corning. You can expect an average low temperature of 20°F in the coldest months of winter.

Remember that the actual date of last frost may not be accurate from year to year because it is based on the USDA zone info for Corning and it will vary from year to year. Half of the time in Corning it frosts late in the year after February 15 so always be ready to cover your liatris in the event of one of those late frosts.
