It looks like a ficus carica, but it could be a seedling and a caprifig which would need pollination from the fig wasp. It could also be a common fig that bears fruit with no pollination. Only time will tell. Do you see baby figs on it? They usually appear at the leaf nodes. There are many varieties of edible figs and it's impossible to identify without a photo of a leaf, a whole ripe fruit, and that fruit cut in half showing the inside.

Thanks Suzi. My Sis said it had fruits last season.

This year have her take a close up of a leaf with a whole ripe fig and a cut ripe fig next to a quarter for size. THEN we'll have a better chance for ID. We need to know the color of the outside of the fig when ripe and the color of the inside of the fig. Tell her to describe the flavor best she can. Is there a crunch? Does it taste like berry, figgy, rich, honey. Is the skin thick or thin? Does it produce a Breba crop in spring on old wood AND a main crop in fall on new wood, or only one crop. If so when? :-) You didn't know it would be this complicated, did ya? There are over 700 varieties of figs so ID aint as easy as you would think. The leaves look a lot like Brunswick, but other varieties show the same long fingered feature. Your sis can go to this site and scroll through everything to maybe ID it herself: http://figs4fun.com/Varieties.html
