It gets down to minus five Celsius in there in if there's a cold period, but they come through without trouble. I have around half a dozen in growth at the moment, including T. albiflorum (often mistakenly called T. sessilifolium), T. brachyceras and T. incisum. I've also got a T. tricolorum (or is it T. tricolor?) growing in the heated house all along the lighting cables. All of these will flower in the early spring. The ones growing in the cold house are hopelessly tangled up amongst a number of Bomarea, so I guess it will all be pretty spectacular! Incidentally, I totally agree with Jane's later note. Both Tropaeolum and Bomarea takes holidays some years if the combination of light and temperature aren't right. However, determining the correct mix is not something I have the patience to work out, so I just enjoy pot luck! Best regards, David Victor
