A flower grew (4)
I believe the answer is:
rose
This clue is a double definition.
'a flower' is the first definition.
(I've seen this in other clues)
'grew' is the second definition.
(rise can mean to grow or increase)
(Other definitions for rose that I've seen before include "Flower - climbed" , "Flower - ascended" , "Garden flower" , "was being promoted" , "Went up; plant" .)
