Thanks for your advice, Dave and Puncdoc. Have just been in the greenhouse sowing some bicoloured ones for next year - Blue Ripple, Erewhon and Maloy. Forgot to check if they are scented but it is too late now.
Next year I won't give them any tomato food until they show me they are making an effort to flower on their own. They'd better shape up next time!
