Rubus alceifolius
Giant bramble (Rubus alceifolius) is a scrambling, prickly perennial shrub with white flowers and red fleshy berries. It can form dense thickets that outcompete native plants and restrict movement of people and animals, including access to water. It can also climb over trees and contribute to branch fall in windy conditions, and it can grow in pastures reducing productivity.
Identify it
Field cues
01Scrambling prickly shrub with canes up to 5m long
02Hooked prickles on stems (about 2–4mm long)
03Large lobed leaves with 5–7 shallow lobes and toothed edges
Distribution records are indicative. Always confirm current status with your state biosecurity authority.
Found in: rainforest edges, rainforest gaps, roadsides, pastures, sugarcane, creekbanks, gullies.
This species can form dense, prickly thickets and spread by both seed and rooting canes, making infestations persistent and able to expand from edges and gaps. Seed can be moved by animals and water, and stem material can establish new plants if moved or dumped. Management commonly requires preventing fruiting and limiting movement of plant material, with repeat treatment sometimes needed for thick clumps.
1
Dig out small plants
Remove small plants by hand digging where practical. Use protective clothing to reduce prickle injuries.
2
Prevent fruiting with slashing
Slash infestations before fruit develop to limit growth and reduce seed production.
3
Spot spray actively growing foliage
Apply a foliar spray to actively growing plants and ensure full foliage coverage. Repeat treatment may be needed for thick clumps.
Use chemicals to the label. Always read the current APVMA-approved label before application.
Check permit conditions for your state, as some uses are limited to council or government staff.
Aquatic situations require products registered for use in or near water.
Why it matters
Impacts
Restricts movement and access
Dense thickets can restrict movement of people and animals and reduce access to water.
Impacts native vegetation
Dense growth can outcompete native plants, especially along rainforest edges and in canopy gaps.
Tree damage risk
Plants can climb over trees and contribute to branches falling in windy conditions.
