Pro tip: Although this tree thrives in partial shade, planting it in full sunlight will result in the best blooming.
It’s difficult to discover this wisteria tree! Before they are all gone, get yours today! For zones 5, 6, 7, 8, or 9, the wisteria tree is the ideal flowering tree.
The tiny trees known as wisteria are notorious for growing quickly, reaching heights of 3 to 5 feet annually. This tree will begin to bloom three to five years after it is planted.
This little tree grows well in grow zones 5-9. It tolerates a variety of soils and does well in full sun to part shade exposure. To accommodate a mature spread of 10–12 feet, space plants 15 feet apart.
Give this tree lots of room because it is invasive and could suffocate nearby native trees and bushes.
Make sure your Wisteria tree is planted in a location and under conditions that will allow it to grow successfully. Although spring and fall are the best periods to plant, you can grow your wisteria at any time of the year as long as the weather isn’t too harsh.
Although the wisteria tree may thrive in both full sun and partial shade, more sunlight will result in more blossoms. Wisteria are highly versatile and even drought tolerant once they have established themselves, despite preferring moist, well-drained, nutritious soil. For the first two to three months, water thoroughly with a hose around twice a week. A 2 inch layer of mulch will aid in weed control, root protection, and soil moisture maintenance. Apply a slow-release fertilizer in the spring.
Just new growth produces wisteria blooms. Therefore, pruning can help you receive the maximum blooms possible. For optimal results, prune at least half of the previous year’s growth in late winter. Pruning is needed to keep the canopy rounded.
For the first year or so after planting, your wisteria tree might need to be staked. These trees grow quickly, and their canopies can be heavy for young trees.
Your landscape will be brought to life by the wisteria tree! This tree will look great in your landscape and home! This unusual tree will anchor the corners of your house and give color, beauty, and flair unlike anything else! For a spectacular display, arrange three wisteria trees together in a corner of your yard. Around this magnificent wisteria tree, create a mixed bed, a nice cottage garden, or both.
Types of wisteria:
There are two varieties of wisteria: Asian and American. Although aggressive growers, Asian wisterias are well-known for their stunning blossoms. American wisterias are less aggressive and still produce beautiful blossoms. Compare the most popular wisteria varieties.
Flower color:
Wisteria comes in a range of colors, such as white, pink, and blue tones, in addition to the well-known purple blossoms. If you believe you have seen a yellow wisteria flower, it was probably a golden chain tree (Laburnum).
Foliage:
Wisterias are deciduous, which means that when the weather becomes chilly in the fall, they lose their leaves. The misunderstanding is occasionally brought on by a different vine known as evergreen wisteria (Millettia reticulata).
Avoid planting aggressive wisterias close to your home as they can cause damage and have even been known to destroy buildings.
Wisterias can be grown in full sun or partial shade, but to promote healthy bloom development, make sure the vines get at least six hours of direct sunlight everyday. If you reside in a colder area, pick a planting location that is protected because a heavy spring frost can harm the flower buds.
Create a planting hole that is the same depth as the plant and twice as wide, then level the plant with the soil surface. Because the vines will soon fill in, you should space your plants at least 10 to 15 feet apart along the support structure.
Wisterias don’t need much care once they are planted to promote healthy growth. Water frequently over the first year until the roots take hold.
After planting, wisterias could take some time to come out of dormancy and might not start to leaf until early summer. They will leaf out at the regular time the following spring, but don’t be surprised if they don’t bloom. Wisterias take three to five years to reach full maturity and may not start blooming until then.
Wisterias grow quickly and can reach heights of up to 10 feet in in one growing season. That works out well if you need to quickly cover a fence or pergola but don’t want the vines to take over your landscape. Regular pruning (once in the summer and once in the winter) not only controls wisteria’s growth but also encourages more robust flowering by creating a framework of horizontal branches and causing spurs to grow at regular intervals.
Cut back the current year’s growth to five or six leaves in July or August, or roughly two months after the plant flowers, to get rid of stray shoots and make short branches that will produce flowers the following year. Summer pruning needs to be done more frequently. Re-prune the plant in January or February while it is dormant by removing two or three buds from the growth from the previous year.
The first few years of wisteria’s growth are crucial for creating the desired framework for the plant’s development. As soon as your wisteria begins to grow, start connecting particular lateral shoots to its support structure. You should also cut down any extra growth. An aggressive pruning may be required on elder plants to promote the growth of new branches. Cut down aging branches to the main primary stem to accomplish this. The spaces will soon be filled with new side branches that can be connected back into the support structure.

What variety of wisteria should I buy?
As long as you give the vine something to climb on, you could use nearly any variety of wisteria to successfully cover a wall in your house. However, a cultivar with shorter racemes—the term for the flower bunches—rather than extremely long, dangling blossoms would have the nicest appearance.
The finest option for a house’s walls is Wisteria sinensis. Usually, their racemes are no larger than 12 inches. The cultivar “Jako” features lovely, fragrant white flowers. Choose ‘Prolific,’ which will continue to bloom throughout the summer, if you want the classic purple blossoms.
However, it’s always a good idea to weigh native against invasive types while picking Wisteria for your home. Because wisteria is such an aggressive and invasive vine, some places don’t allow certain varieties.
Where shouldn’t wisteria be grown?
In order to support the massive vine, the wisteria’s root system extends out widely and dives deep. Do wisteria roots exhibit aggression? Yes, wisteria’s root system is highly aggressive. Avoid planting wisteria next to walls or walkways because of its extensive and strong root system. These are easily harmed by a wisteria’s root system.
Experts advise inserting a corrugated panel about 6 feet (1.8 m) long and several feet (1 m) broad beside the plant to redirect the roots if you find a wisteria close to a building or pathway.
Can wisteria grow on a fence?
Wisteria sinensis or W. floribunda are the two species that we grow the most frequently. The former Chinese wisteria bears its flowers prior to the development of its leaves. The blossoms of the Japanese wisteria floribunda develop simultaneously with its foliage. These details have a significant impact on the species you should choose to raise. W. sinensis thrives on vertical surfaces (house walls, fences, trellises), where its bare blossoms will be best seen. It is preferable for W. floribunda to grow up and over strong arches, arbours, and pergolas. As a result, the longer racemes (bunches of flowers) can hang down and be completely free of the leaves.
How to plant wisteria
Wisterias grow best in soil that is fertile but well-drained. Even though they perform best in direct sunlight, they can tolerate little shade. They can be grown in big containers. To prevent a “rain shadow,” make sure plants are 30–40 cm away from the base when growing up a vertical surface (the dry, shaded area closest to the base of walls and fences). Back the shoot up toward the ground.
Wisteria can be grown into a free-standing specimen; more on that later.
Training wisteria as a climber
When preparing Wisteria to climb, there are only four guidelines to remember:
- In July or August, reduce the whippy shoots from the current year to just five or six leaves. This improves bud formation and speeds up wood ripening by increasing air movement and light penetration through the leaf.
- In January or February, perform a second cut, only removing two or three buds.
- Strong, taut training wires positioned horizontally along a wall or fence are used to train desired shoots. Use soft twine to secure shoots to these wires.
- If it’s necessary to remove old, diseased, or unwanted shoots, wisteria will react nicely to hard pruning. However, be cautious since shoots entwine around one another; you don’t want to unintentionally harm good, productive growth.
Training wisteria as a free-standing specimen
In your garden, grow a few free-standing wisterias for something a little different.
- Plant a wisteria with a single stem next to a reliable support (1.5m or more). The single stem should be tied in and let to extend all the way to the support’s top.
- In the first spring after it has reached the peak, cut off the single stem tip.
- Trim the upper side shoots to 15 to 30 cm in length and remove the lower side shoots. The plant now has a sturdy “head” from which to grow.
- August is the time to prune August shoots back to seven leaves once the head has gotten sufficiently woody.
- To keep your shape, trim any old, undesirable head shoots in the winter.
- To reveal flower racemes, trim March shoots back to 2.5 cm of their bases.
Wisteria can endure the winter.
Don’t panic if your wisteria begins to drop its leaves in the fall. Deciduous wisteria predominates. Winter doesn’t keep it green, but the leaves will come back in the spring.
Before dropping their leaves, some wisteria varieties put on a show of fall color as the leaves turn yellow or gold. If it’s happening in the fall, there’s typically nothing to worry about unless you’re also observing other symptoms like an insect infestation. Yellowing and dropping leaves can be signals of disease and other problems.
While Evergreen Wisteria (Millettia reticulata) is more challenging to grow, all true Wisteria are deciduous. Your Evergreen Wisteria will most likely maintain its leaves throughout the year if you have hot summers and brief, mild winters with little below freezing. This is zone 9b and higher in the US, which includes a portion of California and Arizona as well as the southern half of Florida and Texas.
Evergreen Wisteria is deciduous like regular Wisteria in more temperate regions, so you may anticipate it to go dormant for the winter and sprout new leaves in the spring. You probably won’t be able to cultivate Evergreen Wisteria in a location that is colder than USDA zone 8 because even deciduous habit cannot shield it from prolonged, bitterly cold winters.
Canines are wisteria poisonous?
Because wisteria doesn’t have a bad taste, dogs may eat deadly amounts of it.
Wisterias are absolutely gorgeous, with cascades of flowing purple blossoms. However, their leaves and blooms can also be dangerous in excessive numbers, and their seeds (and seed pods) are extremely poisonous to dogs.
Even worse, the results take time to manifest. Wisteria also doesn’t taste unpleasant, making it simple for dogs to consume excessive amounts before you realize there is a problem.
When may wisteria be purchased?
Start by purchasing a Wisteria plant in the spring that is in bloom or has flower buds on it if you want your Wisteria to bloom. Thus, you are assured that it can bloom. A small, just planted wisteria with a few tiny flowers is depicted on the left. The wisteria depicted in the video above, “Wonderful Wisteria,” was first planted in 2007 and reached a height of 3.5 meters, or about 12 feet, within 7 years. By 2018, it had completely covered the wall space at the back of the house. This is evidence of the wisteria’s vitality and the requirement for longer (and longer) ladders to prune it. It’s difficult to believe that this small plant expanded to cover an entire house wall in just ten years.
The best way to buy wisteria is as a grafted plant. Any plant grown from seed is likely to cause issues for you; while it may be less expensive, it may take a very long time to flower, possibly longer than ten years. A protrusion in the stem just above soil level in the plant pot identifies a grafted plant. The base of the Wisteria and the graft bulge can be seen if you watch the video on summer pruning Wisteria at roughly 3 minutes and 40 seconds.
Make sure to thoroughly water a fresh Wisteria plant and watch out that it doesn’t dry out in the beginning. When it’s established, it will take care of itself. I neglected to water the wisteria even throughout the 2018 drought, and it survived. Wisteria is completely hardy, however a protected area is preferred because cold can harm the racemes, or emerging flowers, (see below). Wisteria requires a lot of area and time to flourish and is simple to establish. If space is at a premium, Wisteria can be planted as a standard, which will require careful pruning, or choose a smaller variety like Domino’s or Wisteria brachybotrys.
Wisteria can be grown in a container, although the results will vary. A friend recently asked me for guidance on how to nurture a wisteria in a container after the plant failed to blossom. It bloomed magnificently the next spring after I advised taking it out of the container and replanting it in a bright location. Given the challenges in getting Wisteria to bloom, growing it in a container increases the challenge.
