I was about to buy a wisteria at a garden centre when the sales lady asked if I realised it would not flower for 5 years. Her explanation was that wisteria does not flower for 7 years, and these plants were 2 years old.
I wondered if it was possible to buy 6-year old wisterias which will flower in 1 year?
I realise that this is rather OT, so as a subsidiary question, can anyone recommend a good gardening newsgroup?
