Part of England where flowers grow (4)
I believe the answer is:
beds
'flowers grow' is the definition.
I can't judge whether this definition defines the answer.
'part of england' is the wordplay.
'part' becomes 'bed' (bed is a kind of part).
'of england' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'bed'+'s'='BEDS'
'where' acts as a link.
Can you help me to learn more?
(Other definitions for beds that I've seen before include "Shortened county" , "Places to sow or to sleep" , "Hospital places" , "County; furniture" , "Small English county" .)
