Chile cultivated new plant (6)
I believe the answer is:
lichen
'plant' is the definition.
(lichen is a kind of plant)
'chile cultivated new' is the wordplay.
'cultivated' indicates an anagram.
'new' becomes 'n'.
'chile' anagrammed gives 'liche'.
'liche'+'n'='LICHEN'
(Other definitions for lichen that I've seen before include "Compound plant not unlike to moss in appearance" , "Tiny plants found on rocks and trees" , "It grows on rocks and trees" , "It occurs on rocks or bare ground etc." , "Plant growing on stone" .)
