We bought a small olive plant quite early in the new year. Kept it
indoors. (can get to -5C or even -10C here) Then shoved it outside
for
the summer in between slightly larger plants.
Then brought it back in a few weeks ago.
It's still a small bush (35cm) but the problem is this, I hadn't
expected it to actually DO anything apart from becoming a slightly
bigger, more filled-out bush.
Suddenly, last week, its got, well... what looks like tiny
fruit-like
buds on flowers-stalk type growths.

That sounds like it's just the start of the tiny flowers that olives
get prior to fruit set. BTW, if you can find a spot in your garden
that has soil which does not get waterlogged in winter, olives will
survive the low temperatures that you describe very well.

From here on just keep the olives growing.
