Blue Moon Wisteria

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.

Blue Moon Wisteria is a striking, flowering vine, and the hardiest of the wisterias. Up to three times in one growing season you can expect showy, fragrant, lavender-blue flowers.

Make sure you plan your site as this vine requires a structure to support its mature weight. Try planting close to a post, trellis, or fence.
