Narrow-Leaved Coneflower (Echinacea)
Nodding Onion

Narrow-Leaved Coneflower is a native perennial wildflower known for its pink to pale purple, daisy-like blooms. The petals (rays) droop downwards, around a dark, domed center, giving the flower a cone-like appearance. The nectar-rich blossoms attract a wide variety of pollinators, including native bees and butterflies. After flowering, the seeds provide food for birds, further adding to its ecological value.

Once established, it is drought-tolerant due to its deep taproot, which also helps stabilize soil. Narrow-Leaved Coneflower thrives in a variety of well-drained soils, including sandy, rocky, and alkaline. It often grows alongside the native grasses that characterize prairie and grassland ecosystems, making it well-suited for prairie and grassland restoration, naturalization, and pollinator gardens.

Nodding Onion is a native perennial wildflower known for its nodding clusters of flowers that range in color from white to pink to purple. The lightly scented blooms provide pollen and nectar for pollinators, especially bees, which can collect while hanging upside down, a capability most other insects lack.

The narrow, grass-like leaves of the Nodding Onion can be used as a seasoning in cooked dishes, though bulbs and raw leaves should not be eaten in large quantities. All parts of the plant have an onion-like aroma when bruised, which helps deter deer and rabbits. They can self-seed readily, so removing spent blooms helps manage their spread. Tolerant of a range of soils, including alkaline, it is well-suited for a variety of plantings, including pollinator gardens and naturalization projects.
