Yup, it is different. I got 3 different types from a former employer, who got them from her family estate in Easton... They are DuPonts, the lady who planted them was an orchid/rare plant grower. I think the Purple one is the probably same as LSU Tiger, although it doesn't normally have stripes, and I don't have Tiger to compare directly (a bunch of people I sent cuttings to were going to help me figure it out, clears throat). According to the person who gave them to me the mother trees are at least 50 years old, so it might have come from Dr. O'Rourke shortly after he made the initial crosses, or was added later, the trees are apparently growing together as a hedge.
It is a very sweet fig with a unique fruity flavor, very little fig taste, more like a grape.
