Blue Moon Wisteria

Nuttall’s Sunflower is a native perennial wildflower known for its bright, golden-yellow blooms. Flowering from mid to late summer, it offers a late-season nectar source for various bees, butterflies, and other pollinators, while the seeds provide a fall food source for birds. The upright growth habit adds structural height and visual variety to your landscape.

Nuttall’s Sunflower can be found growing in moist to wet meadows, prairies, and open spaces. It can spread quickly via underground rhizomes, making it ideal for large-scale plantings. It is well-suited for naturalization, soil stabilization, riparian zones, and wetland restoration projects. If planting in smaller urban yards or gardens, extra care and maintenance will be required to limit its spread.

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.
