Dwarfed tree (6)
I believe the answer is:
bonsai
'dwarfed tree' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bonsai that I've seen before include "Mini-tree growing" , "Dwarf tree found in Bosnia" , "Japanese method of cultivating miniature trees" , "Japanese craft of growing dwarf trees" , "Art of dwarfing shrubs" .)
