Hybrid Fruit Tree
I am new to this gardening thing but I am getting into it! I recently purchased a house that has a few fruit trees in the back yard. I am told there are 2 apple trees and a plum tree(bare at the moment). There is also a lemon/lime hybrid tree which is bearing fruit. The crazy thing is, there is an orange growing on the back of the same tree! Is this even possible? A tree growing lemons, limes and oranges? There is a tag around the trunk that says Valencia Oranges, although there is currently only one growing that I see. There are quite a few lemons of various sizes all over the tree.
Any help on an explaination would be great!
