Wisteria macrostachya 'Blue Moon'
Experience the legendary beauty of Wisteria with a high-performance twist. The Blue Moon Wisteria (Wisteria macrostachya) is famous for its incredible ability to rebloom up to three times per season, offering waves of fragrant, foot-long flower clusters from late spring until the first frost. This cold-hardy North American native is a vigorous climber that quickly transforms arbors and pergolas into a "Blue Moon oasis." If you are looking for a fast-growing, drama-filled vine that provides more flowers for more of the year, this is the definitive choice for your landscape.

A Season of Endless Blooms: Blue Moon Wisteria While most Wisteria varieties offer a single fleeting moment of beauty, the Blue Moon Kentucky Wisteria is a game-changer. This vigorous deciduous vine produces enormous, grape-like clusters of sweetly scented flowers in a stunning blend of deep purple and lavender-blue. As a reblooming variety, it doesn't stop after the first spring show—it can flush with new flowers up to three times a year, keeping your garden vibrant well into late summer.
Why Choose Blue Moon?
Triple the Flowers: Unlike traditional types, Blue Moon is bred to rebloom, ensuring your garden stays fragrant and colorful for months rather than weeks.
Massive Flower Clusters: The "racemes" (flower hanging chains) can grow up to a foot long, creating a dripping "waterfall" effect of blue and purple.
Extreme Cold Hardiness: One of the toughest varieties available, it is hardy down to Zone 4 (and even Zone 3 in protected spots), making it a survivor in harsh climates.
Fast Growth: Reaching 15–25 feet quickly, it is perfect for those who want to establish shade and privacy in a short amount of time.
Landscape Versatility
Sophisticated Shading: Train it over a sturdy pergola or patio deck to create a living ceiling of flowers that provides natural cooling and a heavenly scent.
Vertical Drama: Perfect for large trellises, terrace walls, or even old windmill frames. Its counter-clockwise twining stems add a soft, romantic texture to hard structures.
The "Wisteria Tree": With a sturdy stake and regular pruning, Blue Moon can be trained into a magnificent standalone "Standard" tree—a breathtaking centerpiece for any formal garden.
Naturalized Privacy: Use it to cover chain-link fences or rock walls to turn functional boundaries into lush, flowering screens.
Expert Care & Maintenance
Sunlight: Requires Full Sun. While it can grow in partial shade, you will only achieve that legendary "triple bloom" power if it's placed in a hot, sunny location.
Water & Soil: Prefers moist, slightly acidic, well-drained soil. It loves consistent moisture, especially during the hot summer months.
Support: This is a powerful, heavy vine. It must be planted on a sturdy, permanent structure (heavy-duty wood or metal) that can support its weight as it matures.
Fertilizer Tip: Avoid high-nitrogen lawn fertilizers near the base, as they encourage leaves but can delay flowering. Use a phosphorus-rich fertilizer to boost bloom production.
Pruning: Lightly prune after the first set of flowers to maintain shape. Shorten summer "spires" of new growth to encourage the plant to focus its energy on flower buds.
