Blue Moon Wisteria

Blue Moon Wisteria _ solves the two biggest problems with growing wisteria in American gardens: invasiveness and cold hardiness. Unlike the Asian wisteria varieties that can become aggressively invasive in American landscapes, Blue Moon is a native North American species _(W. macrostachya) that behaves beautifully in the home garden. And where Asian wisterias are typically limited to Zone 5 or warmer, Blue Moon is cold-hardy through Zone 3 — bringing the most spectacular fragrant flowering vine in the garden to northern gardens where wisteria has never been possible before. Three flushes of sweetly scented 12-inch blue clusters bloom from spring through late summer. Deer resistant, heat-tolerant, and vigorous across Zones 3–9.

Blue Moon may take 2–3 years before first bloom, and up to 4–5 years in some cases. The wait is worth it — once established, the bloom display is extraordinary.

Three Bloom Flushes — Spring Through Late Summer

The repeat-blooming habit is what sets Blue Moon apart from most wisteria varieties. Standard wisteria blooms once in spring — a spectacular but brief display. Blue Moon follows its primary spring flush with two more flushes through summer and into late summer, delivering masses of sweetly fragrant blue clusters across a much longer season. The 12-inch pendant clusters are outstanding for cut flowers and fill the surrounding garden with a rich, sweet fragrance during each bloom period.

Native North American Species — Non-Invasive

The invasiveness of Asian wisteria (W. sinensis and W. floribunda) in American landscapes is a genuine ecological concern — both species are listed as invasive in many states and can overwhelm native vegetation. Blue Moon (W. macrostachya) is native to the south-central United States and doesn’t share that invasive behavior, making it the responsible and ecologically sound choice for American home gardens. All the beauty, none of the concern.

Cold-Hardy to Zone 3 — Wisteria for Northern Gardens

Zone 3 cold hardiness is genuinely extraordinary for wisteria. Most gardeners in Zones 3–5 have been told wisteria isn’t possible where they live — Blue Moon changes that entirely, performing reliably in cold northern gardens that would eliminate most flowering vines. Requires sturdy support — a pergola, arbor, or heavy trellis — as the vine matures into a substantial, vigorous plant.

Why Gardeners Choose Blue Moon Wisteria

• Native North American species — non-invasive, unlike Asian wisteria varieties
• Three bloom flushes — spring through late summer, not just a single spring display
• Sweetly fragrant 12-inch blue clusters — outstanding for cut flowers
• Cold-hardy to Zone 3 — wisteria for gardens where it has never grown before
• Deer resistant and heat-tolerant — adaptable across Zones 3–9
• Requires sturdy support — plan for a pergola, arbor, or heavy trellis at planting
