Blue Moon Wisteria Vine

Cascading lavender-blue blooms, intoxicating fragrance, and the cold-hardiness to thrive where other wisterias won't survive — Blue Moon is the wisteria for the rest of us.

Blue Moon Wisteria (Wisteria macrostachya 'Blue Moon') is an American native wisteria that delivers everything you love about the classic vine — long, pendulous clusters of fragrant lavender-blue flowers, fast-climbing growth, and a lush, romantic presence on pergolas, arbors, and fences — with one major advantage: it's cold-hardy to Zone 4. That means gardeners in the Upper Midwest, New England, and other cold-winter regions can finally grow a wisteria that actually survives and thrives. And unlike some wisterias, Blue Moon reblooms — producing multiple flushes of flowers through spring and summer.

What I love about it

Blue Moon is the wisteria that changed the game for cold-climate gardeners. The fragrant lavender-blue clusters are stunning — long, graceful, and intensely perfumed. It blooms in spring, then comes back again in summer for a second (and sometimes third) flush that most wisterias never deliver. It's a fast grower that covers structures quickly, and it's less aggressive than Asian wisteria species, making it easier to manage. Plant it on a sturdy pergola, trellis, or fence where you can sit beneath it in bloom and just breathe. That's the whole point.

Plant Care Tips

• ☀️ Light: Full sun — 6–8 hours daily for best blooming
• 💧 Water: Water regularly until established; moderate water needs once mature
• 🌡️ Temperature: Hardy to -30°F (Zone 4) — far more cold-hardy than Asian wisteria
• 🪴 Difficulty: Easy — less aggressive than Asian varieties; requires sturdy support
• 🐾 Pet Safety: Toxic to cats and dogs — all parts of the plant are poisonous
• ✂️ Pruning: Prune after each bloom flush to encourage reblooming and control size
