Edible tree fruits, nuts, and leaves
The following trees have edible fruits or other parts. Not all parts of edible fruits may be edible. Some people may experience idiosyncratic allergies or other bad reactions. Trees.stanford.edu recommends you do not eat any foraged plant material. Should you do so – just as in the case of fungi – be both positive of the identification of the plant and fully aware of the preparation requirements and potential dangers. Some trees mentioned in Trees.stanford.edu may no longer be found at the designated locations because they have been removed.
