Sulphur-Flower Buckwheat is a native perennial wildflower known for its dense clusters of cream to yellow flowers. The long-lasting blooms persist from late spring into summer, providing an extended nectar source for a variety of pollinators. The flower buds are often red-tinted before opening. As the blooms age, they shift to orange or red, adding seasonal interest and making them well-suited to dried flower arrangements. Its seeds are also eaten by birds, adding to its ecological value.

Depending on climate and conditions, Sulphur-Flower Buckwheat may be evergreen to semi-evergreen, or its foliage may turn red during fall. Its deep roots and spreading growth stabilize rocky or sandy soils, making it useful for erosion control. Exceptionally hardy once established, it requires little care and thrives in challenging environments, making it an excellent choice for pollinator gardens, naturalization, and ecological restoration projects.

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.
