Veins around creepers (5)
I believe the answer is:
vines
'creepers' is the definition.
(I've seen this in another clue)
'veins around' is the wordplay.
'around' is an anagram indicator.
'veins' anagrammed gives 'VINES'.
(Other definitions for vines that I've seen before include "Grapes grow on them" , "Plants that climb and twine" , "Grape plants" , "Wine is ultimately the fruit of these" , "Climbing or trailing plants" .)
