Not sure of the species. The olives were field dug from the CA north country and are fruit bearing. Sorry not to be of more help.

Thank you Jonathan for responding. I’m Trying to find a nonfruit dwarf olive tree for our patio that has light pavers... here in the Bay Area..

Many nurseries carry non-fruiting olives. Just a simple question you need to ask them. Link here for a little more information.
