Our new home has a Wisteria bush that has taken over the patio cover since we moved in. It is so disorganized and unsightly while it is dormant, therefore I want to remove it. I’m trying to come up with a replacement that is a little greener all year round. One that draws butterflies and birds would be a plus. The sun will be shining directly on the dry ground. I appreciate any advice you may give me.
ANSWER:
There is a gorgeous North American native wisteria called Wisteria frutescens that is not nearly as invasive as the Asian wisteria, or Wisteria sinense, which is likely what you have. Unfortunately, that natural wisteria does not flourish in California and only grows as far west as Texas. You will require semi-tropical flora in Riverside County’s westernmost region, close to the Mexican border. We will search for both in our Recommended Species for Southern California because you did not specify whether you wanted a shrub or a vine to cover your patio. Unfortunately, we were unable to locate any native Southern California evergreen vines; hopefully some of the flowering evergreen shrubs we did locate would serve your needs.

Wisteria is able to grow in California.
I left Omaha, Nebraska, where I was an enthusiastic gardener, and relocated to the desert near Palm Springs, California. Wisteria will grow in this area, when summertime temperatures might reach 120 for several weeks. When might I be able to anticipate seeing it blossom here if it grows? I appreciate your support.
The only wisteria native to North America, Wisteria frutescens (American wisteria), is not a native to California. It is indigenous to the Eastern United States, in USDA Hardiness Zones 5 to 8, and as far west as east Texas. Zone 9b through 10a appears to encompass your location in Riverside County.

How long does Californian wisteria bloom?
By mid-April, the wisteria should be blooming, depending on the conditions. For two to three weeks, the blooms should be in bloom. Once more, everything is based on the weather.
3–4 weeks in the early to midspring, according to my research. However, I would call the Gardens and get this verified. Bees also accompany wisteria flowers!
I’m grateful. I had intended to get married there while the wisteria was in bloom, but I suppose I would be at the whim of mother nature.
April through May, in response to our inquiry. By late May, imagine may be hazy. My advise is to simply dial.
I’d speak with Hakone. It depends on the weather, and I have one in my side yard. The majority of its leaves have fallen off, and I don’t believe it will blossom till late march.
In Southern California, can Chinese wisteria flourish?
Getting out with the holiday mall crowd or staying in on a December Saturday to trim the wisteria—I’m not sure which is worse. You should hang out with the wisteria. You can give the gift of perennial weeping flowers with just a few thoughtful cuts.
Any blooming shrub, vine, or fruiting tree requires some knowledge when it comes to pruning because an untrained gardener can easily remove the buds that create the blossoms. The key is to tell the plump flower buds from the thin leaf buds.
A good book on photo-based trimming is helpful. Before you prune, visit the library to acquire a book that makes sense to you if you are the parent of a wisteria that has been obstinate and hasn’t blossomed since you planted it. You’ll become an expert at pruning after a few seasons.
Leguminosae, which means pea family, includes wisteria. Other members of the tribe, notably sweet pea, garden pea, and lupine, also have the well-known pea-like petals.
The two widely used varieties are Japanese and Chinese wisteria. Japanese wisteria blooms when the vine begins to leaf out; the highly-fragrant flowers emerge from the vine’s base and progress upward.
The most popular variety of wisteria planted in Southern California is Chinese wisteria. Before the leaves arrive a few weeks later, Chinese wisteria blooms all at once on bare branches in clusters of light fragrance.
Wisteria can take eight to ten years to blossom after being started from seed (I’ve done this once). It is preferable to choose a mature plant that will bloom in the first year or so with proper pruning.
In the early seasons, concentrate your pruning efforts on creating a structure that appeals to you. Strong wisteria can grow into a tangled jumble of branches and streamers extending in every direction if left to their own ways.
Forego the blooms at first, and pinch and trim to create a sturdy center trunk instead. Select and train the streamers that will one day act as blooming branches. Disconnect from anything else.
Keep this in mind once your vine has grown (this takes a year or two).
Too much green growth will drain the plant’s energy and prevent it from producing blossoms. Think high and tight for the greatest flowers. Remember that stems trained horizontally will blossom more successfully than those trained vertically.
Ideally, the plant should be heavily pruned in the summer. Reduce the gangly streamers even further in the winter to just two or three flowering buds per stem. Each flowering shoot should be pruned three to six inches from the support structure.
In case you were wondering, if a wisteria doesn’t want to bloom, feeding won’t make it do so. Actually, mature wisteria thrives when given a little extra care.
By cutting back the roots in the winter, you can further harm wisteria plants that have never blossomed. Cut the roots 4 feet from the plant’s base to 18 inches deep using a very sharp shovel. Next, wish for springtime blooms like you would with any gardening project.
Can wisteria survive a hot climate?
Wisteria sinensis is a noxious, invasive plant that shouldn’t be grown in gardens since it flourishes in the warm climates of the United States. Plant Wisteria frutescens if you want to cultivate a wisteria vine and live in a warm climate. This natural vine to America can reach heights of up to 40 feet while remaining non-invasive and hardy in USDA zones 5 through 9. In the middle of April, right after the leaves start to grow, the fragrant, lilac-purple blooms of the vine appear in 6-inch racemes.
Grow Millettia reticulata instead. The wisteria-like vine Millettia reticulata, also known as evergreen wisteria, is hardy in USDA zones 8 through 10 but is not invasive. Evergreen wisteria has leathery, glossy leaves and tiny, fragrant summer blossoms that grow to a height of around 16 feet. Plant Hardiness Zone 10 experiences winter temperatures between 35 and 40 degrees F.
Where in Los Angeles can I locate wisteria?
At numerous locations across the San Marino gardens, the vibrant purple favorite is in the midst of a lovely peak.
- San Marino’s Botanical Gardens, Art Museum, and Huntington Library.
- Weekends and holidays require reservations (in addition to a ticket)
Where can wisteria be found?
It is well known that wisteria take a very long time to bloom. For two to three years after planting, don’t anticipate blossoms. Some readers swear by the following technique to encourage blooming:
- To cut into part of the roots, take a shovel and drive it 8 to 10 inches into the ground approximately a foot and a half away from the main trunk of the wisteria.
- Approximately half of the roots should be damaged for the shrub to be shocked into reproduction (flowering).
- Don’t worry—impossible it’s to harm this unchecked, unwieldy, frequently invasive shrub!
- The flowers of wisteria can also be impacted by chilly winter temperatures.
Native Wisteria
Consider growing a wisteria species that is indigenous to North America if you live there, such as:
- Wisteria frutescens, also known as American wisteria, thrives in zones 5 through 9. Its original states span from Virginia to Texas, the southeast to Florida, and up into New York, Iowa, and Michigan in the north. The vine is 25 to 30 feet long, has glossy, dark-green leaves, and after the plant has begun to leaf out, develops huge, drooping clusters of lilac or purple-blue flowers. Only new wood will display the blossoms. Notably, the blossoms are typically less aromatic than those of Asian wisterias.
- In zones 4 to 9, Kentucky wisteria (Wisteria macrostachya) flourishes. Similar to American wisteria, this late-bloomer is a native of the Southeast of the United States (it is sometimes considered a variety or subspecies of American wisteria). The Kentucky wisteria is the quickest to blossom, bearing faintly fragrant bluish-purple flowers after only two to three years of growth.
- A gorgeous, silvery-blue cultivar of the native Kentucky wisteria called “Blue Moon” is particularly hardy. In late spring or early summer, it blooms. It can go as chilly as -40F. (-40C).
Non-Native Wisteria
- Despite the fact that they are frequently marketed at nurseries and garden centers, Chinese wisteria (Wisteria sinensis) and Japanese wisteria (Wisteria floribunda) are non-native, invasive species, hence we do not suggest them for North American gardens. They can reach lengths of 30 to 60 feet and are hardy in Zones 5 to 9. (and beyond in the Southern U.S.). Japanese wisteria comes in two popular kinds, including:
- Popular plant known as “Honbeni” displays clusters of pink flowers in the late spring.
- “Alba” (also known as “Shiro Noda”) yields beautiful clusters of snow-white flowers in the late spring.
Are Wisteria Toxic to Pets and Humans?
Yes, the wisteria plant contains lectin and wisterin, which are poisonous to people, animals, and even pets. If taken in significant quantities, these poisons can result in anything from nausea and diarrhea to death.
If pets or young children frequent the area, it is a good idea to remove the seedpods after the plant has flowered because the material is particularly concentrated in the seeds and seedpods. Unaware children or animals won’t think twice about eating as many seedpods as they can because they are not unpleasant to taste or have an instant effect. In case of ingestion, contact your neighborhood poison control center.
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.
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.
