Flowers taken to a northern town or part of London (10)
I believe the answer is:
bloomsbury
'part of london' is the definition.
(I know that Bloomsbury is part of London)
'flowers taken to a northern town' is the wordplay.
'flowers' becomes 'blooms' ('bloom' can be a synonym of 'flower').
'taken' says to put letters next to each other.
'to a northern town' becomes 'bury' (I've seen this before).
'blooms'+'bury'='BLOOMSBURY'
'or' acts as a link.
(Other definitions for bloomsbury that I've seen before include "Flowers cover an area of central London" , "capital area" , "part of central London" , "Name of Virginia Woolf, Lytton Strachey group" .)
