Companion Plants
When planted with other native wildflowers and prairie species, purple coneflower can form a diverse and resilient garden ecosystem. Excellent companions include:
•Black-Eyed Susan (Rudbeckia hirta): Their bright yellow blooms contrast beautifully with purple coneflower’s deep hues.
•Blazing Star (Liatris spicata): Offers vertical texture and complements the clumping habit of coneflower.
•Native Grasses (e.g., Little Bluestem – Schizachyrium scoparium): Provide a soft, textural background that enhances the wildflower mix.
•Tickseed (Coreopsis spp.): Their extended blooming period and cheerful colors help create a layered, diverse planting

Ecological Importance
•Pollinator Support:
The abundant nectar and pollen of purple coneflower make it a magnet for bees, butterflies, and other beneficial insects, which in turn aid in the pollination of surrounding plants.
•Wildlife Food Source:
Its seed heads provide an essential winter food source for birds, such as finches, contributing to overall biodiversity.
•Soil Health & Ecosystem Stability:
With its deep taproot, purple coneflower helps improve soil structure and stability, while its inclusion in native plantings supports a resilient and diverse ecosystem.
