The single biggest choice in wisteria gardening is whether to plant an Asian species or an American native. The choice has implications for vigor, invasive risk, bloom reliability, and structure requirements.
Species comparison
Per Missouri Botanical Garden, the principal wisteria species available in US gardens:
| Species | Origin | Vigor | Zones | Bloom Timing | Invasive Status |
|---|---|---|---|---|---|
| Wisteria frutescens | Native (eastern US) | Moderate | 5–9 | Spring; reblooms summer | Not invasive |
| W. macrostachya | Native (central US) | Moderate | 4–9 | Late spring | Not invasive |
| W. sinensis | China | High | 5–8 | Spring (before leaves) | Invasive in 29 states |
| W. floribunda | Japan | High | 4–9 | Spring (with leaves) | Invasive in most of eastern US |
Per NC State Extension, Chinese and Japanese wisterias are listed as invasive plants in states including Virginia, Pennsylvania, Georgia, Tennessee, and many others. They spread by root runners and seed and can colonize forest edges and roadsides from garden plantings. In these states, the native species are the responsible choice.
