Bower (6)
I believe the answer is:
arbour
'bower' is the definition.
(I know that bower can be written as arbour)
This is all the clue.
(Other definitions for arbour that I've seen before include "Shady alcove; bower" , "Secluded garden alcove" , "Retreat" , "Sheltered leafy glade" , "Shady place among trees is in garden" .)
