Hardy partner of the green shrub (6)
I believe the answer is:
laurel
This might be a double definition.
'hardy partner' is the first definition.
(I've seen this in another clue)
'green shrub' is the second definition.
'laurel' can be an answer for 'shrub' (I've seen this before). I'm not certain of the 'green' bit.
'of the' acts as a link.
Can you help me to learn more?
(Other definitions for laurel that I've seen before include "Hardy's partner - symbol of victory" , "Evergreen shrub" , "Oliver Hardy's comedy partner Stan ......" , "Hardy's comic pal" , "Evergreen tree also called bay" .)
