Primrose (7)
I believe the answer is:
cowslip
'primrose' is the definition.
(I know that cowslip is a type of primrose)
This is all the clue.
(Other definitions for cowslip that I've seen before include "Early spring flower" , "Flower related to primrose" , "Yellow spring flower" , "Type of primrose" , "Yellow flower for unsteady bovine?" .)
