Tropaeolum tricolorum, Bolivian Nasturtium.

Erm, sorry MG, (thank heavens its you, you don't mind being disagreed with, lol) but its Eccremocarpus scaber. It is a perennial climber, but is usually treated as an annual here because the winter often kills it off. Having said that, I lived in my last house for 6 years and had one all that time. Save seed just in case if you like it - its easy to grow.

Good job you knew what it was Bamboo... Bulba thought it was Tropaeolum too, lol. Sorry about that Jackie.

Ok thanks will save some seed just in case. :-)
