Himalayan blackberry (Rubus armeniacus)

Himalayan blackberry

Rubus armeniacus


  • Stiff, 5-angled stems can grow 3m tall and 12m long
  • Produce green, large, toothed leaves that are generally grouped in fives for first year stems and threes for older stems
  • Berries are black, shiny, hairless and edible
  • Flowers are small and white or pinkish with five petals and are arranged in clusters

Consequences of invasion

  • Competes with native shrubs by blotting out the sun
  • Create dense thorny thickets that impede the movement of wildlife (and humans)
  • Reduce visibility along road ways and take over stream channels and banks and roadside ditches

How is it introduced? How does it spread?

  • Deliberate planting by humans for berry harvest
  • Root and stem fragment start a new plant
  • Feces of animals that eat black berries spread seeds

Integrated Pest Management Options

  • Be PlantWise! Choose plants that are native to the local area by Growing Me Instead! 
  • Watch for plant parts clinging to your clothing
  • Avoid having bare soil or disturbed ground on your property
  • Mow continuously throughout the year or when the plant is beginning to flower
  • Tillage or cutting combined with mowing
