Plant from stall is about to be returned (5)
I believe the answer is:
basil
'plant' is the definition.
(basil is a kind of plant)
'from stall is about to be returned' is the wordplay.
'from' indicates a hidden word.
'to be returned' says the letters should be written in reverse (I've seen 'is returned' mean this).
'lisab' can be found hidden inside 'stall is about'.
'lisab' in reverse letter order is 'BASIL'.
(Other definitions for basil that I've seen before include "Aromatic herb in pesto" , "Fellow" , "Aromatic herb with purplish-green leaves" , "Herb (from Fawlty Towers?)" , "named Cardinal Hume" .)
