Wisteria typically blooms in spring and early summer. The exact timing depends on the variety and location zone:
- American Wisteria blooms mainly in late spring and can produce occasional flowers through summer (Zones 5–9).
- Chinese Wisteria blooms from early spring to early summer (Zones 5–8).
- Japanese Wisteria blooms mid-spring through early summer (Zones 4–9).
- Kentucky Wisteria blooms late spring through early summer (Zones 3–9).
- Silky Wisteria blooms late spring through early summer (Zones 5–8).
In general, wisteria flowers appear in spring and may carry on into early summer, often peaking in April through June depending on climate and variety. In some places like Lake Como, Italy, for example, wisteria season is typically late April to early May. Wisteria flowers are known for their long cascading clusters and fragrant blooms, making spring and early summer their prime display time.
