The Azorean viburnum, an evergreen shrub with corymbs of white flowers and glossy metallic blue berries. It is a cousin of mainland laurustinus and shares its warning.

Where it grows

Oak woods · Scrubland · Uplands

Also known as

Azorean laurustinus

In flower
In fruit

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

Harmless confusion

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.
