Introduction

The Wisteria vine belongs to the Leguminosae family of Flowering plants, Fabaceae. It has ten woody climbing vines (twining vines). These vines are native to China, Korea and Japan, as well as the Eastern U.S.A.

Hygrophila diformis is an aquatic flowering tree or plant that bears the name “water wisteria”. It belongs to the Acanthaceae family. Some species are common ornamental plants.

Thomas Nuttall, a botanist, stated that he named Wisteria after Caspar Wistar (1761-1818). Questioned about his spelling later, Nuttall said it had been for “euphony”, but his biographer speculated that it’s going to have something to try and do with Nuttall’s friend Charles Jones Wister Sr., of Grumblethorpe, the grandson and relative of the merchant John Wister.

According to some sources in Philadelphia, the plant was named after Wister. Because the spelling is seemingly deliberate. There’s no justification for changing the genus name under the International Code of Botanical Nomenclature. Some spell the common name of the plant “wistaria” or pronounce it that way.

How to plant and grow Wisteria

A high-climbing vine, Wisteria flowers vigorously in Spring with large, drooping bunches of lilac or bluish-purple flowers.

Wisteria is a vining plant that can live for many years. It produces beautiful cascades of purple and blue flowers, which look stunning when hung from an archway or trellis in the Spring and summer. This vine can grow to be quite large, reaching up to 30 feet in length.

Wisteria vines can grow into almost any crevice or crook they reach. It is best to avoid planting them too close to your house.

Wisteria flowers have a wonderful fragrance and scent, making them an excellent choice for your senses. A brownish, bean-like pod forms after blooming and stays on the plant until Winter or other cooler months. Only new growth will produce blooms.

Notify your gardener if you plan to plant Wisteria. The lectin and Wisterin can be found in any part of the wisteria plants. They are poisonous for pets, livestock, as well as humans. These poisons can cause diarrhoea and even death in severe cases.

Are the Wisteria Plants invasive?

Wisteria Sinensis (Chinese Wisteria) and Wisteria floribunda (Japanese Wisteria) aren’t native to North America. In some states, they are considered to be an invasive species. Alternatives to the Asian species include American Wisteria, Kentucky wisteria (Wisteria macrostachya), and American wistaria (Wisteria. frutescens).

We recommend you choose one of the North American species if you want to add a new wisteria plant to your garden.

What is the difference between North American and Asian Wisteria species?

Asian Wisteria grows aggressively with fuzzy seed pods. However, North American Wistaria is not as aggressive in its growth. It has smooth pods and fruits but more tubular, bean-shaped seed pods.

The American & Kentucky Wisteria blossoms appear after the plant has fully leafed & enters the late Spring. However, the Chinese Wisteria flowers appear before the leaves.

Wisteria Vines – Planting & Cultivation

WHEN DO YOU PLANT WISTERIA?

Plant in the Spring or fall when the plant is dormant.

Wisteria can be grown from seeds, although it takes a while to mature and bear flowers. You can either buy wisteria plants that are already established or take a cutting.

WHERE TO PLANT WISTERIA

  • You can plant in full or partial sun. Wisteria can grow in shaded or partially shaded areas, but it won’t likely flower. It is vital to get enough sunlight.
  • You can plant Wisteria in well-drained, moist soils that are fertile and well-drained.
  • You can add compost to soil that is not in good condition. Otherwise, Wisteria will thrive in most soils.
  • Find out more about soil improvement and how to prepare the soil for planting. Read: How to Prepare Garden Soil for Planting | Planet Natural
  • Avoid other plants. Wisteria can quickly grow and could easily take over its neighbours.
  • Wisteria can also grow onto and into nearby structures like sheds, garages, houses, etc. We recommend that Wisteria not be planted too close to your home.
  • Wisteria vines need a sturdy frame to climb on and grow. This could be a metal or wooden pergola, trellis, or trellis. It is not uncommon for mature plants to become too heavy or over-weighted and may even break their supports or leverage materials.

Wisteria can be beautiful climbed up the side of homes or residential buildings. However, it is best to plant with caution as wisteria vines can easily find their way into any crack or crevice.

HOW TO PLANT WISTERIA

  • Dig a hole two to three times the depth of the root ball.
  • Plants should be spaced 10 to 15 feet apart.

How to plant and grow Wisteria

Wisteria is a vine that climbs high. Wisteria flowers vigorously in Spring with large clusters of lilac or bluish-purple flowers.

This is how to plant, grow and care for Wisteria in your yard or garden.

Wisteria is a vining plant that can live for many years. It has beautiful cascades with blue and purple flowers. This vine can grow to be quite large and fast, often reaching over 30 feet in length.

Wisteria flowers have a wonderful fragrance and smell, making them an excellent choice for your senses. After blooming, the brown pod, which looks like a bean, remains on the plant through Winter or other cold months. Only new growth will produce blooms.

Take care when planting Wisteria! The wisteria plant contains lectin and Wisterin, which can be toxic to animals, humans, and livestock. If consumed in large quantities, these toxins can cause diarrhoea and nausea, and even death.

Wisterias climb by growing their stems around any support or structure. W. Sinensis twines in the opposite direction to W. floribunda, Japanese Wisteria. W. Sinensis twines from above clockwise. This is a common way to identify the two most common species of Wisteria.

They can reach 20 m (66 feet) and spread out 10 m (33.3 feet) laterally. The Sierra Madre in California is home to the largest Wisteria plant in the world. It measures over 1 acre (0.40ha) and weighs 250 tons. It was planted in 1894 and is a type of ‘Chinese lavender.

The leaves are alternate and 15 to 35 cm in length. They are pinnate with 9 to 19 leaflets. The blooms are presented in pendulous racemes, 10 to 80 cm in length, almost like Laburnum.

They are still purple, violet and pink, but they can also be white. The leaves are not yellow. In some Asian varieties, flowering occurs in Spring (just before or after the leaves open) and in the middle to late summer for American species & W. japonica.

Some species’ flowers are fragrant, such as W. Sinensis. Wisteria plants are used as food sources & plants by the larvae of some Lepidoptera(moths & butterflies) species, including brown-tail.

Like Laburnum’s seeds, the seeds are grown in pods that look almost identical to Laburnum’s. They are also poisonous if eaten, just as Laburnum’s seeds. The bitter-tasting toxin wisterin is found in all parts of the plant. It can cause nausea, vomiting and dizziness.

It is still disputed whether the amount of poisoning-causing chemicals in the seeds are sufficient. Over the years, Wisteria seeds have been a source of poisoning in children and pets from many countries. They can cause mild to severe gastroenteritis as well as other symptoms.

How to cultivate Wisteria

Wisteria, particularly Wisteria Sinensis is, is extremely hardy and fast-growing. Although it can tolerate poor soils, it prefers fertile, well-drained and moist soils. It can thrive in direct sunlight or full sun.

It can be propagated by hardwood cutting, softwood cuttings or seed. It can take a variety grown from seeds over ten years to flower.

Gardeners tend to grow plants from root cuttings or grafted cultivars that have proven to be productive. Ten species of woody climbing vines are found in flowering plants belonging to the Leguminosae, Fabaceae.

Wisteria Vines Facts

What is the growth rate of the wisteria vine?

Wisterias take a long time to mature and may not begin flowering until three to five years after being planted. They are quick growers and can reach 10 feet or more in a single growing season. This is great if you need to quickly overlay a fence or pergola, but it doesn’t work well if you don’t have the time and can overwhelm your garden quickly.

Where can Wisteria grow at its best?

Wisterias Produce flowers Best In full sun, choose a pergola or wall facing south or West. They should be in well-drained, fertile soil. They will Grow In light shade, but flowering will decrease.

Is Wisteria poisonous to dogs?

These climbing growers can be beneficial in sprucing up your landscape and vertical space. However, they can also pose a danger to your health. These plants can poison dogs or cats from the wisteran produced inside of them, so they are best planted out of reach of pets and domesticated animals.

What other plants can I grow next to Wisteria?

Clematis & Wisteria

They can make great companions. Both can grow happily together on the same arch or trellis, and both can reach for the sun. They look much more appealing when combined than if they are grown separately.

Which month does wisteria flower?

Spring. It’s all about a series of blooms.Mid September to October is the time Wisteria blooms.

Do I need to remove the Wisteria seed pods?

A healthy wisteria plant will produce seed pods in late summer & autumn. The pods hang from the vine, just like peas.

To keep a mature or full-grown wisteria plant blooming, it’s best to cut the seed pods off. Left alone, the pods will ripen, & you’ll have seeds shooting out many feet around the plant.

Are the Wisteria Plants invasive?

Wisteria sinensis (Chinese Wisteria) and Wisteria floribunda (Japanese Wisteria) are not native to North America. In some states, they are considered invasive species.

Native Wisteria, American Wisteria (Wisteria macrostachya), and Kentucky wisteria are excellent alternatives to the Asian species. If you’re considering adding a new species of Wisteria, we recommend you stick with one of the North American species.

Wisteria Flowers Art and Symbolism

Wisteria and its racemes were widely used in Japan over the centuries. They are a famous symbol in family crests, heraldry and were well-liked symbols in Japanese heraldry. The Fuji Musume, also known as “The Wisteria Maiden”, is a famous kabuki dance. It is the only dance from a series of 5 personifying dances during which a maiden transforms into the spirit of Wisteria.

Wisterias are used in the West in both building materials such as tiles and stained glass.
