 Biology and ecology

  • Spurge laurel is a perennial shrub
  • All plant parts are toxic to humans, dogs, and cats, but the berries can be eaten by birds
  • This plant is a native species of England, Wales, and the Channel Islands; it is also native in some African countries
  • It has escaped ornamental plantings but is no longer widely sold by the nursery industry
  • It grows well in drained, loamy clay soils that are neutral to slightly acidic & tolerates dense shade

Control

Prevention – Learn to identify plants; start monitoring early in the season

Biological – There is an aphid in New Zealand, the Myzus persicae, that carries the carlavirus to which the plant is said to be susceptible

Cultural – Planting grass or another cover crop can help keep seeds from germinating

Mechanical – Young plants can be pulled; Plants that are 3 years or younger can be cut off with a 95% mortality rate (make sure to wear protective gloves) older plants should be cut below the soil line

Chemical – There are no specific chemical recommendations for spurge laurel but the brush control portion of the: PNW Weed Management handbook may be useful
