This one has quite the controversial history. There was a television show – Burke’s Backyard in Australia in the 90’s. Burke supposedly selected this variety while visiting in Italy. However his website now indicates it is a form of the Rouge de Marmande (which is a French tomato!). Previously the show said it was selected from Costoluto di Marmande which doesn’t exist. So the source is really unknown.
His website indicated it was voted “Best Home Garden Tomato” by a panel of food and gardening experts several years back. It is supposed to be a top selling tomato in Australia.
