Daphne mezereum

Daphne mezereum, commonly known as February daphne, mezereon,[2] mezereum, spurge laurel or spurge olive,[3] is a species of Daphne in the flowering plant family Thymelaeaceae, native to most of Europe and Western Asia, north to northern Scandinavia and Russia. In southern Europe it is confined to medium to higher elevations and in the subalpine vegetation zone, but descends to near sea level in northern Europe. It is generally confined to soils derived from limestone.

It is a deciduous shrub growing to 1.5 m tall. The leaves are soft, 3–8 cm long and 1–2 cm broad, arranged spirally on the stems. The flowers are produced in early spring on the bare stems before the leaves appear. They have a four-lobed pink or light purple (rarely white) perianth 10–15 mm diameter, and are strongly scented. The fruit is a bright red berry 7–12 mm diameter; it is very poisonous for humans, though fruit-eating birds like thrushes are immune and eat them, dispersing the seeds in their droppings.

Toxicity

Daphne mezereum is very toxic because of the compounds mezerein and daphnin present especially in the berries and twigs. If poisoned, victims experience a choking sensation. Handling the fresh twigs can cause rashes and eczema in sensitive individuals. Despite this, it is commonly grown as an ornamental plant in gardens for its attractive flowers. The native wild version became a protected species in the UK in 1975 under the Conservation of Wild Creatures and Wild Plants Act.[4]
