My husband had this plant prior to our relationship. It's over 13 years old, and has never born fruit of any kind. Husband is adamant it's a fig tree, and I am not knowledgeable enough to argue. It's been pretty sparse with the leaf growth, too. We're curious if it's a fruit bearing tree at all and if it's just going to look like this the rest of its poor life.

Any help would be greatly appreciated.

Thank you!
