My neighbor has an unidentified tree that has not produced a single fruit since she planted it 3 years ago (with no southern sun, in the Pacific NW).  I think the leaf looks like my Stella.  Are there any (or a lot) of Stella leaf look-alikes?  It came from a nursery in Oregon, so it's probably not something very obscure.  

 

That could actually be a Black Mission or a lot of other varieties. Leaves, with a few exceptions, tell you very little that will help ID.

Tell her to pinch her tree and feed it some good liquid fertilizer.  She should get fruit unless her tree is a tissue culture tree.  Mine never fruited after 3 years and is now in fig heaven!

It looks like my Damatie leaves, it is from cuttings last year, 3 Ft tall, potted tree with one breba now, Hopefully some main crop later.

It also looks like Vasilika Sika,

Looks like a verns brown turkey leaf, I have an unknown variety with the same basic leaf shape just a bit fatter at the tip of the center lobe.

Great, good to know it could be something else.  I have a Vern's Brown Turkey and the leaves look different from the Stella and hers.  I just gave her tree a good pruning, it was kind of a disaster.  She actually thought she was overfertilizing it, I'm not sure where she got that idea.  Its in a spot that gets very wet and boggy in the winter, but that hasn't inhibited the growth.  My 3 year old stella has produced figs but none of them have ripened.  But I"ve read on these forums of people in zone 6 with good results with Stella, so hopefully it will do better as it gets older.  I'm going to move the container from western sun exposure to southern sun exposure.
