How to Start It
★ Recommended for beginners
Buy a grafted, named plant (a flowering variety joined onto sturdy roots), since wisteria grown from seed can take 15 to 20 years to flower, if ever. In cold regions, choose a hardy North American wisteria, which blooms more reliably after hard winters. Plant it around your last frost in full sun, 3 m from other plants, next to a very strong support.
Wisteria is a huge, long-lived vine with hanging clusters of fragrant flowers in late spring. It grows fast and heavy, so it needs a strong support and pruning twice a year to flower well instead of just making leaves.
When To Start
Wisteria needs warmth. Wait until your last frost has passed and the soil has warmed before sowing.

Water your new wisteria plants well while they settle in. Deep and slow is best.

Planting & Sprouting
Growing Tips
- 1Plant wisteria in full sun, since shade means few flowers.
- 2It grows in ordinary soil with a little compost, and rich soil only makes more leaves.
- 3Water deeply every week for the first summer, then only in long dry spells.
- 4Skip extra feeding, because too much food drives leaves instead of flowers.
- 5Give it a heavy-duty frame and keep it away from gutters, roofs and siding, which its stems can pry apart.
- 6All parts of wisteria are toxic, especially the seed pods, so keep children and pets away from them.

Harvesting
When to Pick
Fragrant flowers drape in late spring; the twice-yearly prune is what keeps them coming
How to Harvest
- 1Wisteria is grown for its flowers, and pruning twice a year is what makes them.
- 2In midsummer, cut the long, whippy new shoots back to about 5 leaves from the main stems.
- 3In late winter, shorten those same shoots again to 2 or 3 buds, which become the flower spurs.
- 4Tie the main stems to the frame as they grow, and remove seed pods after flowering so children and pets cannot reach them.
