What's over the hedge?
Is this a barrier? Or an invitation?
Does it command silence, or feed speculation and wonder?
Is it a feature in itself, or does it add definition to some other feature?
What I like about a natural hedge like this versus a Colourbond fence: it offers partial glimpses and flashes of light and colour. Colourbond says absolutely "This is where your space ends." This isn't quite so cut-and-dried.
