Small flower stand (5)
I believe the answer is:
brook
I believe this is a double definition.
'small flower' is the first definition.
(a small stream, ie something that flows)
'stand' is the second definition.
('brook' can be a synonym of 'stand')
(Other definitions for brook that I've seen before include "Bear - small stream" , "running water" , "stomach" , "Allow" , "Stream; put up with" .)
