Adapts iris to make a house plant (10)
I believe the answer is:
aspidistra
'a house plant' is the definition.
(I've seen this before)
'adapts iris to make' is the wordplay.
'to make' is an anagram indicator.
'adapts'+'iris'='adaptsiris'
'adaptsiris' anagrammed gives 'ASPIDISTRA'.
(Other definitions for aspidistra that I've seen before include "Star is paid (anag) - plant" , "The biggest - (in the world) (Gracie Fields)" , "For Asian native" , "Huge house plant" , "leafy plant" .)
