quelle che seguono sono due risposte date alla stessa domanda, posta da qualcuno nel forum inglese; spero ti siano utili (poi magari ci saprai dire..
):
"There's one in Sidcup, called Ruxley Manor Garden Centre which has a lovely selection"
"I'd try the Columbia road plant market. I know it's somewhere in the east end and a quick search on the internet should give all the directions you need. It's only open on a sunday and starts from about 7am until I think about 2pm. They should have a fair few CP's at this time of year and when I went it September they had loads of Nepenthes and I managed to haggle a N x Gentle down to 4 quid".
