Money you and I brought back for evergreen tree (6)
I believe the answer is:
cashew
'evergreen tree' is the definition.
'money you and i brought back' is the wordplay.
'money' becomes 'cash' (I've seen this before).
'you and i' becomes 'we'.
'brought back' is a reversal indicator.
'we' backwards is 'ew'.
'cash'+'ew'='CASHEW'
'for' acts as a link.
(Other definitions for cashew that I've seen before include "snack perhaps" , "Chew as you would this nut" , "Edible nut" , "Kidney shaped nut" , "Acajou" .)
