Elleme's Garden
Berberis darwinii
Genus: Berberis.
Species: Berberis darwinii.
I have this in the front garden. Bought when a thug ripped out the box bush there and a neighbour suggested that I tried 'nature's barbed wire' instead! Great for bees when in flower, and blackbirds love the berries.
Prune after flowering is over but try to conserve the berries for the birds.
