( photo / image / picture from carolyn keiper's Garden ) There is just nothing to explain this tomato.
Carolyn, not everyone would be able to grow a duck tomato. Keep this up, and you'll have a meal-in-one--meat,vegetable,fruit (since there is some discussion whether a tomato is a fruit or a vegetable). You could be part of averting a world food crisis. Marketing would be easy--the Kieper ducmato--with a catchy name like that, gardeners would be fighting over seeds!
