Bark of an Olive Tree

Olive trees get old and gnarly, very old. But even as young trees they will appear weathered and rugged. This one year old tree already has a beautiful knot. It's bark is rough to the touch and looks dry. This aged characteristic of olive trees reminds me of the history of this tree. How throughout the ages it has come to symbolize ancient societies and simple pleasures. A token of an olive branch sends the message of peace and mutual understanding. Yet, does this tree even flower?
PS - olive harvests appear to be high around the world this fall. I think its a good omen.
