Wisteria sinensis (Chinese Wisteria)
Wisteria sinensis, native to China, boasts stunning purple-blue and violet-blue flowers with a touch of lilac-white. These fragrant blooms form long racemes ranging from 15-40cm and appear from late April to June. Unlike its cousin, the Japanese species, sinensis twines in a counter-clockwise direction and typically produces flowers on exposed stems. While the racemes may be smaller, they make up for it with a more intense scent. This deciduous plant is a must-have for any garden.
Caution: This plant is harmful if ingested
Flowering time: May - June
Height: 9m
Frequently Asked Questions
When is the best time to plant wisteria in the UK?
Autumn or spring are both suitable, as long as the soil isn’t frozen or waterlogged. Planting in autumn often helps roots settle before the next growing season.
How often should I prune wisteria for reliable flowering?
Most gardeners prune twice: once after flowering in summer, then again in late summer to keep shoots tidy and encourage flower buds for next year. Regular pruning also helps control spread and keeps it manageable on walls and trellis supports.
Why isn’t my wisteria flowering yet?
Common causes include too much shade, over-feeding, or the plant still getting established, especially in its early years. Also check whether it’s grafted (often flowers sooner) or grown from seed (can take much longer to bloom).
Will frost damage wisteria in winter?
Wisteria is generally hardy, but late frosts can sometimes nip young shoots or buds in early spring. A sheltered position and avoiding overly early soft growth (from high feeding) helps reduce risk.
