Not Canterbury Bells, that's Campanula media, a biennial.. These are Campanula persicifolia, a perennial.
looks like a cornus but I don't know which one.
It's likely to lean towards the sun, you can turn it to avoid that
are little white roots appearing on the stem? (in the water)
I've just got one called Diablo d'Or (or something like that) I shall be interested to see the colour through the season
Of course it's leycesteria. I just don't do forum arguing
I think it will be in that deutzia type group
Shouldn't Daiseys be Daisey's (in true GC speak)
they do spread but the fancy varieties are not as strong as the basic species in my experience
bamboo is in the grasses family, that's not a grass.
Someone else will turn up soon to ID it for you
Leycesteria formosa. It seeds around and maybe not what your mum planted in the pot
