Funnel-shaped flower (7)
I believe the answer is:
petunia
'funnel-shaped flower' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for petunia that I've seen before include "Colourful" , "Plant related to tobacco" , "Common garden 13 across" , "Common garden plant" , "Plant cultivated for its white, pink, blue or purple funnel-shaped flowers" .)
