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.

Upright Prairie Coneflower is a native perennial wildflower known for its vibrant flowers, which range from golden yellow to dark rust-red with yellow edges. Rising on tall, slender stems, the flowers’ drooping petals surround a central cone. They bloom from midsummer into fall, attracting butterflies, bees, and other pollinators. After blooming, the florets on the cone eventually develop into seeds, which provide a food source for birds.

Its upright growth habit allows it to grow in clusters, creating a striking display. Due to its deep taproot, Upright Prairie Coneflower is drought tolerant, making it well suited to dry areas and xeriscape gardens. Low-maintenance and deer-resistant, this wildflower is a great choice for adding vibrant color and ecological value to any landscape.
