Dear All, For the three species grow (T. tricolor, pentyaphylum , brachyceras) I haze no need for tubercuttngs. Reproduction by seeds succedes excedingly well. Last Septmber sowing is now 10cm high, but 2006 sowng is now 150cm (60") high and will surely flower next month. Their vigor surprised me so, that I have to increase the wire netting to the height og 300cm (10ft) as it is for the adult tubers. T tricolor will soon become available in large quantities and I will sjurely put them out next season in the garden without any protection. An italian customer specialising in growing climbing plants for the wholesale market, intends to put up a line of Tropeolum tricolor which will find their way into the garden centers in Europe.
