Warden Amos off touring plant (6,7)
I believe the answer is:
meadow saffron
'plant' is the definition.
(meadow saffron is a kind of plant)
'warden amos off touring' is the wordplay.
'touring' indicates an anagram (touring can mean moving around).
'warden'+'amos'+'off'='wardenamosoff'
'wardenamosoff' anagrammed gives 'MEADOW-SAFFRON'.
(Other definitions for meadow saffron that I've seen before include "Poisonous crocus" , "Naked ladies" , "Flowering plant" .)
