Art of Japanese flower arranging (7)
I believe the answer is:
ikebana
'art of japanese flower arranging' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for ikebana that I've seen before include "exhibiting array of bloomers" , "Japanese flower-arranging art" , "artistic arrangement" , "Artfully fixing bloomers" , "formal display" .)
