Blossom, vehicle and country (9)
I believe the answer is:
carnation
'blossom' is the definition.
The definition and answer can be both plants as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'vehicle and country' is the wordplay.
'vehicle' becomes 'car' (car is a kind of vehicle).
'and' is a charade indicator (letters next to each other).
'country' becomes 'nation' (synonyms).
'car'+'nation'='CARNATION'
Can you help me to learn more?
(Other definitions for carnation that I've seen before include "Pink/white/red flower" , "Oscar Wilde wore a green one" , "Showy flower" , "Feature of many a wedding" , "Pink - garden flower" .)
