How to Start It
★ Recommended for beginners
The only reliable route to flowers in a few years rather than a few decades — a named, grafted plant on a heavy-duty support.
Spectacular cascades of fragrant spring flowers — but it's enormously vigorous and must be managed. Two crucial points: buy a GRAFTED, named, flowering-size plant (seedlings can take 15–20 years to bloom, if ever), and prune TWICE a year — cut the whippy summer growth back in midsummer, then shorten again in winter — which is what forces flowers instead of endless leaf. Give it serious, strong support.

Planting & Sprouting
Growing Tips
- 1Respect its vigour: only plant wisteria where you can give it a heavy-duty support (and away from gutters and roof tiles, which it will invade).
- 2Full sun, twice-yearly pruning, and patience are everything.
- 3Go easy on high-nitrogen feed (it drives leaf, not flower).
- 4Note: all parts are toxic if eaten, so site it thoughtfully around small children.

Harvesting
When to Pick
Fragrant flowers drape in late spring; the twice-yearly prune is what keeps them coming
How to Harvest
- 1The secret to flowers is the two-step prune: in midsummer, shorten the long whippy new shoots back to about five leaves; in winter, cut those same spurs back further to two or three buds.
- 2This builds flowering spurs instead of rampant growth.
- 3Tie everything to a STRONG frame — mature wisteria is heavy enough to pull down weak structures.
