Plant of the lily family (8)
I believe the answer is:
asphodel
'plant of the lily family' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for asphodel that I've seen before include "Flower of lily family - old heaps (anag)" , "Plant of lily family - lop heads (anag)" , "Elysian plant" , "Shop deal (anag.)" , "Lad hopes (anag) - flower" .)
