Hi, it's not a cherry, the growing green fruits are already larger than any cherry I've seen. Also cherries don't all grow together at the tip of a single upright stem, cherries have individual hanging stems. This looks like some exotic that grows in very dry natural conditions, possibly a fig, does this description resemble any fig species? All the local cherries, nectarines and peaches stil have branches full of dark green leaves that will be around for months to come, this tree always loses its leaves by the end of June. It might not be a commonly grown fruit tree even for this area which seems to have every citrus and other fruit tree species that could possibly survive in this climate (which is a lot as long as you water them). Everyone please read my detailed opening description and think about possible exotics, one more thing, the person remembers being told when the fruit is ripe it turns brownish and they look like a bunch of flattened potatoes stuck to a stick! This has to ring a bell with somebody, it's just too unusual not to be readily recognizable. If you have any questions I'll try my best to help, guessing is free, at least if you give me species to look up I'll instantly be able to tell if it's the same tree. Thanks.

floraluk- 'Flowers may have a scent or not. Leaves may have a scent or not. Flowers and leaves on the same plant do not necessarily smell alike.' So, I guess I can conclude it is not the Cherry Laurel because the leaves should have a scent regardless of whether it flowers?

Thank you all! It could have been only from bird droppings,..far away from any houses, looks like it will never bear any fruits since it has no pollinator, ..unless,... I might get some scion wood, [like to know what pears it will be] and also graft another couple of cultivars on this tree for pollination, wildlife can benefit then. One never knows,...it could be a decant Pear. Somewhere in Quebec on a hunting trip in the woods, the hunters came onto a plum tree which had very nice tasting plums, ..it turned out that it's a very hardy plum, European, good tasting! I got it grafted now,..need another couple of years for it to fruit. They think that a bear was feasting on someones plums in town and relieved itself back in the woods. It could also be deer or moose I would think because I had lots of plums last year in the nursery taken away.

If you need the room for the orchard filberts then you will want to take the existing native ones out. Otherwise it is a matter of personal preference - if you might like the native species enough to keep it there. Try reading up on it and seeing if there is anything about it that might interest you. Like non-resistant kinds of orchard filberts local plantings of corkscrew filbert are currently being spoiled by eastern filbert blight. So you may soon see your specimen develop large sections of dead branches. Even to the point where the tree is mostly gone. It says here the two orchard cultivars you mentioned above are highly resistant, so maybe you are attuned to this problem. If not you will definitely want to continue choosing kinds that are.
