Flower of Wolves cut (5)
I believe the answer is:
lupin
'flower' is the definition.
(I've seen this before)
'of wolves cut' is the wordplay.
'of wolves' becomes 'lupine' (I've seen this before).
'cut' means to remove the last letter.
'lupine' with its last letter removed is 'LUPIN'.
(Other definitions for lupin that I've seen before include "Pea relative with tall spikes of flowers" , "Tall garden flower" , "Flower of pea family" , "Nil up in this flower" , "Flower called after wolf" .)
