I guess it depends which culture or area of the world you are coming from.
Do you want to know about European Tree lore, North American Tree lore, South African Tree lore, South American tree lore?
I would imagine that your question could be answered in a very specific way or a very generalised way depending upon what sort of information you want.
Do you want to know just about the metaphysical properties, healing or medicinal properties, mythological occurances or perhaps something else?
Quite a few sites on the net give some good help about European trees because of their association with the Ogham and hence the ancient belief structure which surround them.
