The Spurge laurel Plant is a new invasive plant for most of the south coast, it grows profusely on the BC coastal islands. It is also found in warmer parts of the province, in roadsides, moist woods, and lowland areas. It prefers shade but tolerates a wide range of conditions.

Almost all parts of the plant are highly poisonous to pets, livestock, and humans. The leaves, bark, and berries are toxic when touched or eaten, and can cause skin irritations, blistering, swelling of the tongue, nausea and even a coma from ingesting any part.

The Spurge laurel Plant is a slow-growing, shade tolerant, long-lived evergreen shrub from Europe and the Mediterranean region that has escaped from gardens and naturalized in woodlands and other shady places. Spurge laurel can grow in a wide range of conditions, but it thrives in full to partial shade and well-drained soils. Its primary means of spread is by birds and rodents eating the berries, although it can also spread vegetatively by root sprouts.

The plant is a threat to native species. it thrives in shady areas. Seeds in their blackberries are transported to new habitats by birds and rodents. In its native climate in the Mediterranean, pests and pathogens keep the plant under control, but in British Columbia, it grows unchecked. Unlike many other invasive plant species, It does not require disturbed soil to become established.

It creates dense strands, reducing the light reaching the forest floor and limiting the growth of native plant species. As well, spurge laurel may alter soil chemistry and acidity where it germinates, preventing other plants from growing near it.

As with many invasive plants, spurge laurel likely started out as an ornamental shrub in a garden and escaped. In British Columbia, it has spread to Vancouver Island,  the Gulf Islands, and the Lower Mainland,  and the south coast as far as Seymour inlet area.
