Leaves

As a deciduous vine, the wisteria vine sheds its leaves during fall. It does this to respond to cold temperatures. If the wisteria is evergreen, it is the Millettia reticulata, which commonly confuses people. 

Wisteria vines have leaflets on opposite sides of the leaf stalk. The leaflets are further characterized by its dark green color, wavy margins, and long tapered tips. Older vines are dark gray with lenticels that are light in color. The combination of these features contributes to the wisteria’s distinctive leafy growth.

Flowers

Wisteria flowers are famous for its fragrant showy purple flowers, which could also vary from pink, blue, bluish-purple, and white. Its clustered pendulous form helps create the waterfall effect of the flowers. 

During spring, the wisteria trees will start to bloom and it may extend its beauty until summer. One of the common misconceptions about Wisteria is that it has yellow flowers.

However, wisterias do not have yellow flowers, those are usually the golden chain tree (Laburnum anagyroides). Instead, wisterias produce lovely flower buds that eventually burst into their signature colorful blooms.

Fruit and Seeds

During maturity, the flower gives rise to green to brown bean-like pods that contain seeds. It can extend from 4 to 6 inches long and ripen during the autumn season. 

Growth and Development

Wisteria vine grows vigorously up to 20 meters high, given the right support. Its vast growth and development can either be a pro or a con depending on the situation. If the goal is to let it crawl and grow to serve a certain landscape purpose, it is a pro.

On the other hand, it can be a con if left unsupervised to twine onto existing shrubs or trees. Wisteria vines have a strong grip that can cause serious damage to a plant. Even more, so that it was reported to be invasive in Hawaii and 19 US states.

Grow and Care and Maintenance

Sun Requirement

Wisteria vines flourish when exposed to full sun and will surely bloom more beautifully. However, if placed under shaded areas, the vine should be exposed to full sun for at least 6 continuous hours for the plant wisteria to bloom. 

Water Requirements

Wisteria plants need to be watered moderately, enough to develop a strong root system. It can tolerate short periods of drought but, on the other end of the spectrum, overwatering is a big no. Too much water, when accompanied by nitrogen-rich fertilizers, can also hinder the blossoming of flowers as it makes the plant create more foliage.

Temperature and Humidity Requirements

Growing wisteria in warm and humid environments is ideal. However, reports are stating that the vine can survive low temperatures up to -37 degrees celsius. 

Fertilizer

Fertilizer application is not necessary for Wisteria vine’s growth but to be sure checking the soil’s nutrient content can be done. Fertilizers that are high in nitrogen will promote foliage growth but hinder flowering. On the other hand, phosphorus-rich fertilizers may be added to aid in the plant’s flowering, 

Soil Requirements

Grow wisteria vines in well-draining, fertile soil is ideal. Loamy mixes with a good amount of organic matter like compost are ideal. Ensure the soil drains well to prevent root rot, as wisteria doesn’t tolerate soggy conditions.

A slightly acidic pH (around 6.0 to 6.8) is preferable but not strictly necessary. Amending clay soil with sand and organic matter and adding sand to sandy soil can improve drainage for optimal wisteria growth.

Propagation

Reproducing wisteria vines through its seeds is not recommended as it could take 15 years to bloom. The best way to propagate is by planting cuttings or by grafting. Adding root hormones can also aid in better and faster root development. Watering the plant too little can induce a shallow root system. Remember to give ample amounts of water as the plant creates an established root system. 

Pruning

As a vine, attaching support for the wisteria to climb on is beneficial for its development and training. Wisteria tree can grow upright by training it with support, like a trellis, and trimming any side shoots. Keep in mind that this vine twines in a clockwise direction. Once reached the ideal height, cutting the tip will help stunt its growth. 

In maintaining the wisteria vines, having a regular pruning schedule is recommended since it can grow too fast and might cause detrimental effects on the landscape. Removing dead plant parts and cutting back side branches to at least a foot is a good practice to control the wisteria’s growth. Suckers growing from the base of the plant should also be removed. 

Potential Harm

Despite its majestic appearance, the wisterias can disrupt landscapes by twining and attaching to existing vegetation and killing it. This can be a serious weed problem if not controlled and one way of controlling it is by pruning it regularly. To eradicate, uprooting the plant manually or using herbicides can be performed.

Wisteria vine is often seen used in decorating tunnel pathways in landscapes since it adds shade and is aesthetically pleasing. 

Wisterias can also be trained as bonsai and serve as a specimen plant in the landscape. Wisteria bonsai tree is one of the very popular flowering bonsai trees.
