Bull’s view of a plant (5)
I believe the answer is:
oxeye
'a plant' is the definition.
The answer is an example.
'bull's view' is the wordplay.
'bull' becomes 'ox'.
'view' becomes 'eye' (I've seen this before).
'ox'+'eye'='OXEYE'
'of' is the link.
(Other definitions for oxeye that I've seen before include "Plant with daisy-like flowers" , "Type of daisy" , "Variety of daisy" , "Wild chrysanthemum" , "Daisy-like flower" .)
