Planting a "legacy" tree - Olea europaea or Arbequina olive tree

Olives have been part of my life since the beginning.  My mother had a story about rubbing olive oil on me as an infant, and olive oil was part of our daily diet, no doubt influenced by my family's Sicilian heritage.  I decided to plant an olive tree here at home to leave as a legacy tree for those who live here in the far off future.  Because temperatures are increasing here (and I think they will continue to do so due to human caused global warming) I think olives may well be able to fruit here on the far northern California coast.
I found a beautiful large pot in which to plant the tree.  I want to limit its height to its lower range of 8-10 feet tall.  Here are pictures of the planting.
