Plots with skill turned over for plant used for stuffing (8)
I believe the answer is:
bedstraw
'for plant used for stuffing' is the definition.
(plant used for stuffing mattresses)
'plots with skill turned' is the wordplay.
'plots' becomes 'beds' (bed is a kind of plot).
'with' becomes 'w' (short for with).
'skill' becomes 'art' (both can mean a talent).
'turned' shows that the letters should be reversed in order.
'w'+'art'='wart'
'wart' back-to-front is 'traw'.
'beds'+'traw'='BEDSTRAW'
'over' acts as a link.
(Other definitions for bedstraw that I've seen before include "Plant once used for stuffing mattresses" , "makes a poor lie" , "Plant once used to stuff mattresses" , "Plant formerly used in mattresses" , "Best ward (anag) - plant" .)
