Climbing plant found in varied climates (8)
I believe the answer is:
clematis
'climbing plant' is the definition.
(I've seen this before)
'varied climates' is the wordplay.
'varied' indicates anagramming the letters.
'climates' anagrammed gives 'CLEMATIS'.
'found in' acts as a link.
(Other definitions for clematis that I've seen before include "Old man's beard" , "Climber's" , "Ornamental climber" , "Climbing plant with colourful flowers" , "bloomer" .)
