I went back and bought one (photos pending). A few leaves were 2 1/2 inches, but no larger. As stated before, most were smaller. And they are densely placed up and down the horizontally-growing branches. It would make a great bonsai if it doesn't produce good fruit.
I spoke with the owner of the business. I commented that I thought this one was interesting, as I had not seen anything quite like it and let him know I had several varieties at home. He gave me a pacifying look like "Sure, you do." I doubt he knows there are more than one variety of fig, kind of like China might not exist because he has never been there.
He's a nice guy, but judging from previous conversations, I don't think he is the sharpest tack. I asked him if it was a dark or light fig. He said, "It's plum-colored" and called it "a Southern fig." OK, there are all colors of plums, so I asked again. He said it was purplish-brown. I'll have to see.
