|The Mysterious Fruit Tree in Daniel's side yard, November 2010.|
Hi Bharati, It is very exciting to try to research the identity of my lovely and toothsome mystery fruit tree. I cannot know for certain that this tree is a volunteer. If my memory serves me correctly, there may be a cement cylinder around it which would indicate it is a cultivar.
It is my theory that this tree might be a volunteer hybrid between a peach and an almond. There are many wild almond trees in Mt. Washington, though I have tried the fruit from them and they are not like my tree. The tree was a good size when I moved into this house in 2001.Bharati also sent a fascinating link to an article by Leonard Coates of Morganhill, California from the Journal of Heredity Vol. 12. In it, Coates describes the fruit from a "Peach-Almond" hybrid and includes photographs of the fruit, which shrivels up and splits when it ripens. I have consulted with Daniel and he reports that the fruit from his tree does not do this. As a result, we are forced to conclude that although Daniel's mystery tree may in fact be a cross between a peach and a wild almond tree, it is not the "Peach-Almond" hybrid first identified in the nurseries of W. B West of Stockton, California sometime in the early 1850's.
The trail goes cold once more, but the search continues...
