There are several varieties of wisteria that are suitable for bonsai, but the two most commonly used are the Chinese wisteria (Wisteria sinensis) and Japanese wisteria (Wisteria floribunda). Both of these species are known for their beautiful, fragrant blooms and attractive foliage. Your preferred choice will depend on various factors, such as: growing zone, appearance, hardiness, growth habit and flower fragrance intensity.
Chinese wisteria (zone 5-9) is a hardy and vigorous plant that is well-suited for bonsai, with long, twisting branches that are perfect for shaping and training. It produces clusters of lavender or purple flowers in the spring, which can add a dramatic pop of color to a bonsai display. It is hardier than Japanese wisteria.
Japanese wisteria (zone 4-10) is also a popular choice for bonsai, with slightly smaller leaves and more delicate, drooping flowers in shades of blue, pink, or white. This species is known for its elegant, cascading growth habit, which can be enhanced through careful pruning and training. Flowers of Japanese wisteria have a stronger aroma.
In the end, the best wisteria for bonsai will depend on personal preference and the growing conditions in your area. Both Chinese and Japanese wisteria can make beautiful bonsai specimens when properly cared for and trained. For more details, please read Wisteria bonsai care.

Few challenges a bonsai grower will face while growing a wisteria bonsai are:
- Rapid growth rate: One of the main challenges of wisteria bonsai is its rapid growth rate, which can make it difficult to maintain the desired shape and size of the tree. Regular pruning and training are essential to keep the plant under control and promote healthy growth.
- Test of patience: Wisteria is mainly grown as a bonsai for its flowers. However, this plant takes considerable time to reach maturity and bloom (sometimes 10-15 years).
- Special care needs: Improper watering (dry roots) can also lead to failure to bloom. Hence, the tree needs more care and maintenance.

Keep the tree in a location with stable temperatures and avoid exposing it to drafts or temperature fluctuations.

- Humidity: Wisteria bonsai trees prefer a humid environment, so it can be helpful to place the tree in a location with high humidity. Keep the bonsai pot on top of a shallow tray with pebbles and water in summer to increase humidity around the bonsai. The pebbles will ensure that the bottom of the pot is raised above the water level on the tray.
- Display: Wisteria bonsai trees can be displayed on a table or stand, or placed on the ground in a decorative pot. Consider the size and style of the tree when choosing a display location and pot.
