I have a privet hedge about 3ft high around my vegetable plot. It's old.
It's tired. It need frequent clipping. It's dying.

I plan on replacing it with a light wooden fence, which I intend to screen
with a variety of plants.

I want:

Flowers in the summer and interest (berries/foliage) in the winter.
Little maintenance, apart from the odd bit of pruning.
Good screening of the fence
Variety
Not too thick

Location is west central Scotland.

Suggestions?
