In Canton you can determine when it's the best time to plant echinacea by looking at the USDA zone info.

Planting Calendar for Echinacea

Frost tolerance for echinacea:	Tolerant of a very small amount of frost.

Since echinacea are barely cold tolerant you can plant them a bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant echinacea in Canton is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant echinacea and expect a good harvest is probably August. You probably don't want to wait any later than that or else your echinacea may not have a chance to grow to maturity. Starting your echinacea indoors is a great way to get them started a few weeks earlier.
