How to tell it
Opposite, oval, leathery glossy leaves, paler and hairless beneath, with a smooth edge. Small white flowers in dense flat corymbs at the branch ends. Oval berries of a metallic dark blue, very showy. Range: endemic to the Azores.
What it is confused with
Laurustinus
Viburnum tinus
They are nearly identical and both have metallic blue toxic berries. The mainland one has hairs on the veins beneath and flowers in winter; the Azorean one is hairless and flowers in spring. Neither is eaten.
Open sheet →What it is for
None. The berries are toxic and cause vomiting and diarrhoea, as in every viburnum. The metallic blue is among the loveliest things in Azorean scrub, and that is exactly why it needs saying that it is not eaten.
