Size and Method of Climbing:

Chinese wisteria can grow 25 feet or more. It is a twining vine which climbs by twisting its stems or leaf stalks around a support. This type of vine grows well on trellises, arbors, wires or chain-link fences.

Native geographic location and habitat:

Native to China.

Leaf description:

The opposite leaves are pinnately compound, with 7 to 13 leaflets.

 Flower description:

Blue-violet, pea-type flowers in dangling clusters. The clusters are 6 to 12 inches long with a light fragrance and are produced in mid to late spring.

Fruit description:

Fruit are similar in appearance to pea pods. Seeds are poisonous to eat, as are other parts of the plant.

Plant care:

Full sun is preferable, but this vine will also tolerate partial shade. A moist, well-drained, slightly acidic soil is best. 

Wisteria often do not produce flowers for the first 5 to 10 years. To encourage flowering use nitrogen fertilizer sparingly and use a fertilizer that provides phosphorus, following the label directions.

Proper pruning will also encourage flowering. After flowering, prune excess growth back to 6 inches. These pruned stems will continue to grow. In winter cut them again so that each stem has two to three buds left. Proper pruning not only encourages flowering, but it also helps to manage the size and shape of the vine. Wisteria vines are heavy and  require sturdy supports.

List of pests, diseases, and tolerances:

No serious pests, but this plant is an aggressive grower and has become invasive in some locations. Tolerant of black walnut toxicity.
