A native to the eastern U.S., purple coneflowers are found in many flower gardens. Planting purple coneflower (Echinacea purpurea) in the garden or flower bed draws bees and butterflies, ensuring that nearby plants have plenty of pollinators. The plant also provides a tall background or repeating rows of large (often 6 inches across) purple, daisy-like flowers. The sturdy stalks, which may reach 5 feet in height, rarely bend or require staking for an upright appearance.

Coneflower plants may actually display pink flowers, when the cultivar Echinacea purpurea ‘Pink Double Delight’ is planted.

Growing Purple Coneflowers

Purple coneflower plants grow best in poor or lean soil. Rich or heavily amended soil may result in lush foliage and poor flowering.

When planting purple coneflower, locate them in a full sun area. Full sun is defined as at least six hours of sun each day. In more southern areas, morning sun may facilitate the best performance, with late afternoon shade protecting the plants from burning.

Purple coneflower plants may be started from seed or root division:

  • Seeds – If you wish to collect seeds for next year’s crop of purple coneflower plants, do so before the birds have eaten all the seeds. Place a brown paper bag over the seed head, turn right side up and let seeds drop into the bag. Professional growers believe stratification (chilling) of the seeds for a few weeks, after they are planted in moist soil, produces a more abundant bloom when growing purple coneflowers. Those in areas where temperatures remain warm year long may want to try this technique. Alternately, planting purple coneflower seeds in autumn, in areas with cold winters, allows the seeds to chill naturally.
  • Division – Purple coneflower plants may be started from root division in fall. Only plants that have been in the ground for three years or longer should be divided. Younger coneflower plants may not have developed a root system that is extensive enough for division. Root division should be limited to every three to four years.

Growing purple coneflower from seeds is easy enough for the beginning gardener, while long-time gardeners delight in the ease of how to care for coneflowers.

How to Care for Coneflowers

Once planted and established, learning how to care for coneflowers is easy. In seasons with normal rainfall, additional watering is not necessary. Purple coneflower plants are drought resistant and often thrive in dry summers.

Coneflower care may include limited fertilization, but this is often not needed. If flowers are small or poorly developed, try working in a small amount of well composted material in the soil around the plants.

When late summer blooms of the purple coneflower begin to look tired or ragged, cut the plant back by a third. This rejuvenates the plant and often produces a new display of beautiful blooms that last until frost.

Coneflower care is as simple as that and the plants will reward you with abundant flowering each and every year thereafter.
