Hardy companion in bush (6)
I believe the answer is:
laurel
I believe this is a double definition.
'hardy companion' is the first definition.
(as in the comedy duo Laurel and Hardy)
'bush' is the second definition.
'in' is the link.
(Other definitions for laurel that I've seen before include "Old comic" , "Praise" , "Foliage used in making wreaths" , "Allure (anag)" , "Hardy's comic pal" .)
