Wisteria sinensis
Chinese Wisteria
"
A fantastic vine that can drive many gardeners to frustration when it fails to flower, or when the flower buds are killed by late frosts. That said it is one vine I consider worth the effort and aggravation of the work required to prune it and risk the chance of loosing the blooms to frost.

| Landscape |
| Use on a wall, fence or pergola or it can be trained to grow in a container or the garden as a standard. |
| Cultivation |
| An easy plant to grow given good soil. Some fools propose root pruning to encourage flowering which in my mind is idiotic. Pruning is required twice a year. In March cut current years growth back to two buds and in July cut back current seasons growth to 6 buds, of course prune to train. Do not feed or fertilize, in fact promise neglect and five years after planting it should flower. Plant on a strong support since the relationship will be long term and the limbs can obtain quite a girth. |
