Pamela, thanks for the Ironbark description (the smoother grey-skinned one came up when I googled Irohnbar so we'll try and track seed of that down). The one-o'clock pumpkin is called Crown Prince, a favourite of our pumpkin-rather-than-potatoes neighbour who says it has the best taste. Perhaps it's an Ironbark in disguise!
And, John, I love our "disguised" chickens - could be our Christmas card this year!!
