Lops head off plant in damp habitat (8)
I believe the answer is:
asphodel
'plant in damp habitat' is the definition.
'asphodel' can be an answer for 'plant' (type of flower). I am unsure of the 'in damp habitat' bit.
'lops head off' is the wordplay.
'off' indicates an anagram.
'lops'+'head'='lopshead'
'lopshead' is an anagram of 'ASPHODEL'.
Can you help me to learn more?
(Other definitions for asphodel that I've seen before include "Mediterranean plant" , "Elysian plant" , "Plant of lily family - lop heads (anag)" , "Flower of lily family - old heaps (anag)" , "Lad hopes (anag) - flower" .)
