While traditional blue moons are few and far between, but this particular one will rise and thrill you for months! This robust and fast-growing wisteria can grow to an incredible 25 feet and makes for an unparalleled view as it coats pergolas and trellises in thick purple blooms. The abundance of flowers that Blue Moon delivers offer a sweet and nostalgic fragrance that rekindles those lost days of childhood summers. Because most gardeners value hardiness as well as beauty, this vine was bred to take a beating and sports excellent cold tolerance to the point where it can withstand temperatures as low as -40F! However harsh your winters may get, Blue Moon will come through them with grace and be back blooming in spring like nothing happened. This variety prefers full sun and plenty of rich soil boosted with organic material to give its best performance. Zones 3-9.
