Hi Tony,  Have you ever noticed any thorns on this plant?  

Thanks,  Amy Jo 

Hi Amy, I can't find any thorns on the tree. One thing I noticed was this side of the tree (the thickest, strongest growing limb) bloomed later than the other main branches. I can't find any blossoms on this side that are turning into fruit. Not sure if that is somehow related, or maybe just due to lack of pollination? Thanks, Tony

Hi Toni,  I just can't see enough detail of the leaf, bud and flower to know for sure.  The flower reminds me of flowering quince (chaenomeles sp.), which will produce a large apple size fruit.  But the terminal tip will have a single spine typically. I would wait to see what type of fruit set develops or you could bring a branch sample to our plant clinic at some point so that we can try to identify it.  We are located on the fairgrounds in Redmond near parking lot D.
