Cleo, well done, I grow a few over the winter too, it is a bit faffy sometimes but I love the challenge.
I can usually keep a few Sungolds going till the end on November and sometimes we have planted a couple of Tumblers late and put them in hanging baskets in the kitchen right by the window. I find if they are maturish when I bring them in they do OK.
I would like to find a samller type hanging basket type to play with this concept more.
We are trying with a selection of mini toms this year.
Good Luck, please share as you go with us
