Lid gets left in plant (6)
I believe the answer is:
clover
'plant' is the definition.
(clover is a kind of plant)
'lid gets left' is the wordplay.
'lid' becomes 'cover' (I've seen this before).
'gets' is an insertion indicator (gets can mean captures or absorbs).
'left' becomes 'l' (common abbreviation).
'cover' enclosing 'l' is 'CLOVER'.
'in' is the link.
(Other definitions for clover that I've seen before include "A four - leafed one is for luck (6)" , "Forage plant (that's luxurious to live in?)" , "Meadow plant" , "A 19 down" , "in which we can live luxuriously" .)
