Good advice Allan, but Elaine was asking about olives not figs.
I have had a small olive tree in a pot for about 10 years, it lives outdoors next to the kitchen wall and sort of continues - though never really brialliantly. i've never seen it exhibit the leaf change you describe, nor have I seen this when in southern Spain, where olives are grown by the tens of millions. I wonder if the new leaves are coming from the base? Is it a grafted tree and you are seeing suckers? Leaves can go very odd on trees for reasons, but this is indeed interesting. It is of course possible that it has cheered up as you have put it outside, maybe it now gets more water and food?
