It is a shrub (rarely a small tree) reaching 2–7 m (7–23 ft) tall and 3 m (10 ft) broad, with a dense, rounded crown. The leaves are evergreen, persisting 2–3 years, ovate to elliptic, borne in opposite pairs, 4–10 cm long and 2–4 cm broad, with an entire margin. The flowers are small, white or light pink, produced from reddish-pink buds in dense cymes 5–10 cm diameter in the winter. The fragrant flowers are bisexual and pentamerous. The flowering period is from October to June. Pollination is by insects. The fruit is a dark blue-black drupe 5–7 mm long.
There are three subspecies:
- Viburnum tinus subsp. tinus. Mediterranean region.
- Viburnum tinus subsp. rigidum (syn. V. rigidum). Canary Islands.
- Viburnum tinus subsp. subcordatum. Azores.
It grows mainly in the Mediterranean maquis and in oak forests. It prefers shady, moist areas, at an altitude of 0–800 metres (0–2,625 ft) above sea level.
Viburnum tinus is widely cultivated for its winter blooms and metallic blue berries. It is hardy down to −10 °C (14 °F). The cultivars ‘Eve Price’, ‘French White’ and ‘Gwenllian’ have gained the Royal Horticultural Society’s Award of Garden Merit.
V. tinus has a very beneficial medicinal property. The active ingredients are viburnin (a substance or more probably a mixture of compounds) and tannins. Tannins can cause stomach upset. The leaves when infused have antipyretic properties. The fruits have been used as purgatives against constipation. The tincture has been used lately in herbal medicine as a remedy for depression. The plant also contains iridoid glucosides.
