Small evergreen tree growing out of a crack in a wall.
No interactions present.
Added detail of the bud - hope it helps.
...the needles would be longer, 4" or more (10cm+).
Brave of it to grow halfway up a rock, eh?
How to take close-ups with cheap phone and hand-lens:
Field Guides for Budding Botanists:
As it is growing out of a wall / rock the needle length (and colour) may not be typical - look at the differences between the two different year's needles - it is running out of nutrients!
The lack of papery bud scales is the best determinant of species.
All the best
