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

The last month that you can plant echinacea and expect a good harvest is probably September. You probably don't want to wait any later than that or else your echinacea may not have a chance to grow to maturity. You can get started a couple of weeks earlier by starting your echinacea indoors.
