Flower arranging — love it! (6)
I believe the answer is:
violet
'flower' is the definition.
(I've seen this before)
'arranging love it' is the wordplay.
'arranging' indicates an anagram.
'love'+'it'='loveit'
'loveit' anagrammed gives 'VIOLET'.
(Other definitions for violet that I've seen before include "See 9" , "Mauve" , "Girl's name - colour" , "It nods on Oberon's bank" , "Five-petalled flower" .)
