You can plant echinacea just a tiny bit earlier in the year because they do ok in moderate cold.

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 fully mature. Starting your echinacea indoors is a great way to get them started a few weeks earlier.
