The deliciously fragrant Blue Moon Wisteria (Wisteria macrostachya ‘Blue Moon’) features those amazing, long racemes of sweetly fragrant, purple and blue flowers everyone knows and loves. But this variety can rebloom from June until the first frost.

Blue Moon Wisteria vine is perfect for decorating an arbor or pergola, with the outstanding flowers dripping down below. The stems twine counter-clockwise and grow quickly, up to 15 to 20 feet!

Also known as Blue Moon Kentucky Wisteria, this is an excellent American Wisteria vine for large, sturdy, free-standing arbors, pergolas, posts, trellises, fences or terrace walls. You’ll love the vertical design element in your landscape. It will soften angles and hard surfaces and become a magnificent centerpiece.

The flowers are fragrant and are born in enormous clusters that can be up to a foot long. They hang from this vigorous plant almost like clusters of grapes. The flowers have a lot of purple on the outside of the buds and grow in a fabulous mix of blues and purples. The colors are darker when they first open and can fade as the flowers age. This is a must have for the garden.

Imagine hosting a get together in your outdoor kitchen when Blue Moon is blooming. This dramatic display will be the conversation starter you need to get your guests mingling together.

Children will remember this plant fondly. What an incredible way to introduce them to the wonder of nature.

And for yourself? You’ll delight in an early morning or late evening walk under your Blue Moon oasis. Site this so you can enjoy it. Perhaps you’d find it most useful as a living shade screening the deck off your bedroom? Or let it grow over the patio pergola to bring fragrance and life to your backyard.

Please plan ahead when planting Blue Moon Wisteria. It must be sited and trained only on sturdy structures which will be able to support the considerable weight of the mature vine.

You’ll want to enjoy this experience for years, so give it a “permanent” (and prominent) spot in your garden. Try up lighting the vines with small exterior lights at night to amplify the impact.

How to Use Blue Moon Wisteria in the Landscape

People love using Wisteria flowering vine for a sophisticated look on pergolas and structures to shade high-profile, sunny areas. Once it’s established, it will grow quickly. Trust us, you will want the flowers up close to see and smell them near your entrance or patio areas.

Take a page from history and plant one on a sturdy obelisk for a vertical accent in the garden. Or, repeat a series of obelisks for a fantastic formal focal point. Grow several along the length of a pergola as a perfect choice to add structure a formal landscape.

Carefully train your plant as a flat pruned espalier against a wall or on a trellis. You may have seen them planted on either side of an entrance and trained up and over the top for a very dramatic effect—especially when in bloom.

But don’t box this beautiful plant in, as you can easily use it in more naturalized and informal settings. Turn an eyesore into an asset by growing Blue Moon to cover any chain link fences. Provide careful direction and spread out the growth so it covers the lower portion and along the top of the fence.

Wisteria can also be grown to cover rock walls, or rock piles. People even use them as a groundcover to scramble over rocky and poor soils and rock outcroppings.

Maybe you still have one of those old TV antennae towers or a windmill frame still in place that is crying for a wonderful adornment? Hide it with Blue Moon.

Wisteria do make great smaller trees. Train your plant on a sturdy stake in a sunny location. Remove any branches along the main trunk (or use several trunks to support the plant). Then trim the plant to encourage branching and to form a somewhat rounded head on the plant for a fantastic flower display that simply drips with fragrant flower clusters.

Blue Moon can flower 3 times in a single season. It’s a very versatile plant that loves the sun and will perform beautifully with little care needed.

Tips for Care

Blue Moon Wisteria is one of the best selections to grow in colder regions. It’s hardy all the way down to Zone 4 and that’s cold! Some have even grown it in hardiness Zone 3 and reported that it has done just fine for them, also.

Not only is it hardy, but instead of just the spring bloom, it can bloom sometimes 2 and 3 times in one growing season!

It is important to site your plant in a sunny, well-drained location, as they grow fast and will quickly develop many new roots and develop a lot of top growth. They are more difficult to move once planted, so pick the right spot.

Be sure that you have a heavy-duty support for the plant to grow on. For single stem, tree form plants, make sure the main trunk support is thick and solid to support the top until the trunk thickens enough to support it on its own. Use big, well-built structures to grow it on. Ensure that your fence, trellis, tower, or pergola is strong and sturdy as the plant will grow big and heavy.

It will adapt to well-drained soils, but really loves moist, slightly acidic soils best. Give it a moderate amount of water on a regular basis, and mulch with pine needles to keep the root systems nice and cool.

Avoid planting directly in the lawn. Lawn fertilizers are heavy on nitrogen and may delay flowering, so please limit exposure to them by mulching a bed for your Blue Moon. Use Dr. Earth Acid Lovers Organic and Natural Premium Fertilizer following directions on the package.

Many times, Wisteria can take years before they make flowers so a bit of patience may be needed at planting to allow the plant to develop enough wood to make some nice flowers. Although Wisteria can grow in partial shade, you simply will not see the flower power that Blue Moon can put out so keep it in those hot, sunny locations that they love best.

Do a light pruning right after the first set of flowers are finished to shape and maintain your plants as needed. Careful pruning is needed so the flower buds are not removed.

As summer heat brings on new spires of growth, you may want to shorten them up a bit. Leave half of that new growth and that is the flowers to develop as the plant gets old enough to flower nicely.

There is nothing like a Wisteria in full bloom, and Blue Moon is an outstanding reblooming, hardy variety.
