Climbing plant in variety of climates (8)
I believe the answer is:
clematis
'climbing plant' is the definition.
(I've seen this before)
'variety of climates' is the wordplay.
'variety of' indicates anagramming the letters.
'climates' is an anagram of 'CLEMATIS'.
'in' is the link.
(Other definitions for clematis that I've seen before include "Popular climbing plant" , "Climber's" , "flower" , "Climates (anag)" , "Ornamental climbing plant" .)
