I think it's an ordinary brown fig. That Chicago cultivar probably has a better chance of surviving a cold winter. When I was growing up in Howard Co my Dad grew a fig for decades, and those advanced hybrids weren't available back then. He used to insulate it with straw, but if there was an unusually cold winter it would die back to the roots, and sometimes we thought it was dead, but it just grows back to the same size or bigger. By the time we sold the house a ladder was needed to harvest the gallons of fruit it produced .
We were hoping that in our warmer Anne Arundel winters we won't get much die- back, but were already worried. Our neighbor here grew a fig and insulated it each winter for years, then sold the house. The new owners didn't insulate the fig, and now it's gone.
So far, the deer, squirrels and other pests have eaten most of the fruit.
