Land managers do not generally distinguish between Dog Rose and Sweet Briar Rose.

Both are referred to as Dog Rose, Briar Rose or Wild Rose. Wild Rose is a scrambling, woody, perennial shrub. It is a weed of pastures and native vegetation where it displaces desirable species and provides shelter for rabbits and other pest animals.

Wild Rose (Dog Rose and Briar Rose) is a declared weed under the Natural Resources Management Act 2004 (NRM Act).

Description

  • Wild Rose is a scrambling prickly shrub that forms dense thickets 1-3 m tall
  • the woody stems are erect but arch towards the top. The stems are armed with backward curving spines. Older stems die each year and are replaced in spring
  • leaves are 2-4 cm long with serrated margins. New leaves are produced early in spring and shed in autumn
  • flowers are pink and present from October to December in small groups at the end of the branches
  • fruit is a round, red hip 1-2 cm long. Fruit matures in late summer and seeds are shed in autumn or early winter
  • Wild Rose germinates mostly in autumn and spring. Seedlings are poor competitors with established plants and mostly survive in sheltered areas
  • suckering occurs freely from the crown, particularly if plants are damaged. Suckering results in large, dense clumps.

Impacts

  • Wild Rose can be suppressed by rabbit and stock grazing although suckering is important in reproduction, particularly because juvenile plants are not hardy
  • dense thickets obstruct the movement of stock and can harbour foxes, rabbits and other pest animals
  • invades native grasslands, grassy woodland and watercourses where it displaces native shrubs and ground layer species
  • it is also a pest plant of pine plantations and roadsides.

Distribution

  • Wild Rose is native to Euro-Asia. It is used as a hedge plant in Europe and as a rootstock for ornamental roses
  • in the Mount Lofty Ranges Wild Rose is widespread where annual rainfall exceeds 550 mm. It occurs in roadsides, neglected pasture, pine plantations and native vegetation
  • Wild Rose grows in a wide range of soils, but particularly well-drained, fertile soils
  • the weed is becoming more widespread in the Fleurieu Peninsula and northern hills where it spread in hilly pastures near fencelines or paddock trees
  • fruit are eaten by a range of mammals and birds.

How to control this weed

  • young Wild Rose plants are readily controlled in well-managed pastures by grazing and by competition from pasture plants
  • large shrubs are resistant to grazing. They can be controlled by cutting stems close to ground level and painting the stump with herbicide
  • for advice on chemical control techniques contact your nearest Natural Resources Centre
  • refer to the 'Weed control handbook for declared plants in South Australia' for advice on chemical control. You can find it on the Biosecurity SA website.
