I grow Carolina Cross watermelons for sport. Five days ago I had the pleasure of finding conjoined twins embryos on one of my plants. I pollinated it with pollen from the 291 Kent world record melon and it is growing well. I went ahead and removed other melons that were growing from this vine. This is an extremely rare condition and I could find only 2 other examples of conjoined watermelons on the internet. Both were small type melons and both were grown in China. Mine should get rather large.I am thinking about growing it on its edge to give it a striking appearance. It will look like one melon growing into and on top of another melon.I hope I figure out how to grow it that way as I will have to figure out some good way to keep it from falling over. Your input is appreciated. Here is a link to a picture of it in my growers diary at bigpumpkins.com :
