Climate's changing for this plant (8)
I believe the answer is:
clematis
'this plant' is the definition.
(type of plant)
'climate's changing' is the wordplay.
'changing' indicates an anagram.
'climates' anagrammed gives 'CLEMATIS'.
'for' is the link.
(Other definitions for clematis that I've seen before include "traveller's joy" , "bloomer" , "Climber's" , "Buttercup relative" , "Climbing plant with colourful flowers" .)
