Planting Calendar for Echinacea

Frost tolerance for echinacea:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last 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 Danville is February. However, you really should wait until March if you don't want to take any chances.

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 really do well. If you are starting your echinacea indoors then you might be able to get away with starting them a few weeks earlier.
