Purple Coneflower, Echinacea purpurea
If you want to start growing native flowers, this plant is the place to start!
Purple Coneflower is a perennial native to central and eastern USA. It may grow 2 to 4 feet tall and will produce pinkish-purple flowers that mature in early summer through mid-fall. Several pollinators are attracted to the flower, especially butterflies. Leave some of the flower heads on to produce seeds for the birds.
This easy to grow plant prefers well-drained moist loams but is adaptable to various soil types. It is drought tolerant once established and can grow in full sun to partial shade. It is easily propagated by seed and will reseed itself in the garden.
This is a popular and long-blooming plant for use in the native garden, meadows, pollinator gardens and naturalized areas.
