I found a wild fig growing on the edge of a sidewalk in Allentown, Pennsylvania, which is zone 6.
As you all know figs are not native to the united states. Many seedlings are found growing wild in favorable conditions such as southern CA.
 The street is like a little alley, so the tree is sheltered from strong cold wind.
The owner of the house next to that wild fig, said that he had a fig tree growing about 100 ft away from the wild one. He cut it down about 5 years ago. 3 years ago he noticed the wild fig sprouting in a crack between a telephone pole and the side walk.
The leaves on that figs looked very interesting, pointy and resemble the leaves of a "Brunswick". The owner said that it just started bearing this year and it was a white fig. Could that be a seedling that sprouted?

I just collected a couple cuttings. The owner is about to kill it, since it's growing in a wrong spot. He doesn't seem to enjoy eating figs like we do. I wanted to give the tree a chance. I'm guessing it should be a very hardy fig, not sure of the quality. 

I cannot answer that for you Bass, but i have found veggies growing in my garden which is a good 100ft or more from neighbors garden that i did not grow, i suppose the birds dropped the seeds there in my garden, maybe something similar happend by you or maybe a one in million shot that a bird was carrying wood over for a nest and it somehow dropped in that spot and sprouted.

That fig might come from roots of the original fig.
If not,then is a seed from a polinated fruit bought from store and discarded on pavement.
These are real posibilities.!!

Here's how the leaves look:

The leaves do look very interesting...
About the 'wild' thing, my first impression was that some constapated
bird may have [finally] dropped his/her thing while migrating over the northeast.
But that does not make much sense either for the northbound trip in
spring time when there should not be any ripe figs with viable seeds
(down south) at that time. 

I understand that figs will need to be polinated in order ot produce viable seeds. However I had some fig seeds from my own figs germinate with no problem, they later died of drying up.
So the question is, Do the fig really needs caprification in order to produce viable seeds?

Well, you may have discovered something agaist nature (veeery, veery, very unlikely); let us know... most probably there is another very good
explanation, maybe as Herman previosly sugested.

hi was reading about your wild fig find very interesting. I'm curious if you were able to successfully root cuttings . will be interesting to hear how you do with it ? If you can narrow down what type it is ect,and if it produces nice figs...GOOD LUCK

Yes I was able to root all cuttings successfully. I will post photos of the fruit once they bear. I'm glad I collected cuttings because the mother tree was cut since it was growing in the crack of the sidewalks.

I am looking for cold Hardy figs to plant here in Upstate New York in a high tunnel. How did your cuttings do? Did you get any figs yet?

My tree still haven't fruited, it still small. but there are many figs that should bear for you especially since you're planting it in a high tunnel. You may need to provide some extra protection if there's no heat in there.

Dredging up an old one.  Bass, did this one survive and fruit for you?  If it hung in there did it do ok this past winter?

Bump!!

I'd be more inclined to think there were still live roots underground, and that it sprouted from them.  My parents had an Italian prune tree in their yard.  They planted it in 1954, and cut it down about 25 years ago.  A couple of years ago, the prune tree reemerged right in the middle of a Eureka lemon tree.  The lemon tree is a good 25 to 30 feet away from where the old prune tree grew.
