Wisteria – what are the origins of this plant?
Wisteria (Wisteria speciosa), also known as glycine (Glycine frutescens) or wistaria, is one of the oldest plants currently cultivated in gardens. The species originated from North America, where it was known under the second mentioned name. When it came to Europe, it gained its most common name. As some sources note, wisteria species grow in Asia as well.
What does wisteria look like?
Wisteria is a creeping plant, quite tall, as it can reach up to 10 meters. Additionally, it grows quite fast. Its extensive width and lush flowers are characteristic features which differentiate this plant from others. Smaller wisterias are just a few centimeters tall, while older plants reach about 1 meter in height.
Wisteria – popular varieties
The basic distinction of wisterias involves dividing them into different species. In this case, one can, distinguish the following popular types:
- Chinese wisteria (Wisteria sinensis)
- Japanese wisteria (Wisteria floribunda)
Although both varieties are quite similar, they differ in leaves, blooming times and the length of the branches.
The two mentioned groups contain the most popular cultivars grown in gardens. They are, for example:
- Japanese wisteria ‘Noda’
- Japanese wisteria ‘Alba’
- Japanese wisteria ‘Honbeni’
- Japanese wisteria ‘Domino’
- Chinese wisteria ‘Prolific’
- Chinese wisteria ‘Amethyst’
Apart from the two mentioned species, there are other wisteria varieties as well. They include:
- Silky wisteria ‘Wisteria brachybotrys’
- American wisteria ‘Wisteria frutescens’
- Wisteria x formosa – a hybrid of Chinese and Japanese wisteria.
What is the best location for a wisteria?
Wisteria has some special requirements about the location it grows at. A sunny and warm place is the best option for this plant. It develops better in such conditions. Even a light shade might reduce its blooming rate. Additionally, the location should be protected from the wind. Intense blows might damage the plant’s long branches.
The best soil for wisteria vines
The soil in which a wisteria is growing is just as important as the location. The plant prefers very fertile soil, preferably rich in humus. It should also be quite loose. As for the pH level, it should be slightly acidic or neutral. The soil should be relatively moist – not too wet and not too dry.
Wisteria on pergola – is it a good solution?
Wisteria is a perfect decoration for a pergola, a balcony, or a patio. Because it grows fast, it looks amazing after just a year from planting in such a place. Note that a wisteria planted next to a pergola doesn’t need any additional support. Just control the plant’s branches, making sure they rest against the construction’s elements.
How to grow wisteria in pots?
Many people wonder whether wisteria in pots is a good idea. Planting this species directly in the ground is definitely a much more popular solution – but it doesn’t mean it cannot be planted in containers as well. But if you decide on such a solution, remember the plant needs enough space for a proper growth. Plant young seedlings in large pots, to avoid having to replant them after just a few months.

Sometimes it’s a result of a mistake in the plant’s care, but it might also be caused by fungal diseases such as botrytis. Fortunately, it’s quite easy to resolve.
