Tips For Growing Echinacea (Purple Coneflower)
This genus is invaluable for the mid- to late-summer garden, bringing color into our plantings when many spring bloomers have gone green for the season. They are native to the eastern half of the U.S. and are most commonly found growing in prairie habitats.
Echinacea thrive in our gardens when provided with well drained soils, plenty of sunshine and moderate to dry moisture conditions depending on the species and cultivars. Healthy individual coneflowers will grow in the garden for 3 to 5 years. Species and cultivars raised from seed will often reseed themselves to continue their presence in our gardens.
'Rocky Top Hybrid' echinacea, while xeric, appreciates extra moisture provided by some easily accomplished water harvesting techniques. Plant it in a wide, shallow depression and mulch amply or place right up against the north side of a low, wide rock, tilted to shed water on the Echinacea's side.
Echinacea easily reseeds itself. You can leave the dried seed heads for winter, as they provide food for birds.

USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
- If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
- If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
