Purple coneflowers are found in many flower gardens. 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.
