Lead off to right shrub (5)
I believe the answer is:
alder
'shrub' is the definition.
(thesaurus)
'lead off to right' is the wordplay.
'off' indicates anagramming the letters.
'to right' becomes 'r' (common abbreviation).
'lead' anagrammed gives 'alde'.
'alde'+'r'='ALDER'
(Other definitions for alder that I've seen before include "Tree akin to the birch" , "Tree growing in damp ground" , "Tree whose bark is used in tanning" , "Catkin-bearing tree" , "Shrub or tree with cone-like fruits" .)
