Coil up some rampant wisteria (5)
I believe the answer is:
twist
'coil up' is the definition.
(twist can mean to coil up or turn)
'some rampant wisteria' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'TWIST' is hidden within 'rampant wisteria'.
(Other definitions for twist that I've seen before include "Turn into a distorted shape" , "Unexpected event" , "Who could ask for more!" , "One who asked for more" , "bread" .)
