Answer: Echinacea is a perennial plant that does best when planted in full sun in any moist, well-drained garden soil, but it may also be grown in partial sun. The plant is somewhat drought resistant once established. Coneflowers are hardy in USDA zones 3-9 so it should be winter hardy in your gardening zone. It's normal for the tops of the plants to die down in the winter and new stems and flowers to appear in the spring. The only reason an Echinacea might die over the winter months is if the soil remained too soggy and suffocated the roots. You can dig the plant up and inspect the roots; healthy roots are creamy white inside, dead roots are brown or rusty colored. If the roots are dead, the soil was probably too wet over the winter months; if the roots are still alive, replant your Echinacea and wait for new stems to emerge later this spring. Best wishes with your garden!
