Go through wood on the way back, finding shrub (6)
I believe the answer is:
myrtle
'shrub' is the definition.
(myrtle is a kind of shrub)
'go through wood on the way back' is the wordplay.
'go' becomes 'try' (I've seen this before).
'through' means one lot of letters goes inside another (I've seen this in other clues).
'wood' becomes 'elm' (elm is a kind of wood).
'on the way back' says the letters should be written in reverse.
'try' placed within 'elm' is 'eltrym'.
'eltrym' written backwards gives 'MYRTLE'.
'finding' is the link.
(Other definitions for myrtle that I've seen before include "Evergreen shrub; name" , "Termly (anag.)" , "Evergreen shrub - try elm (anag)" , "Evergreen shrub with dark leaves and white flowers" , "Shrub with white flowers and aromatic berries" .)
