Identification and Reproduction


  • Shiny geranium is an annual herbaceous plant. 
  • Stems are long, brittle, red and can reach up to 35 cm long. Stems spreading laterally or can grow upright up to 50 cm tall.  
  • Leaves are round or kidney-shaped, shiny with 5-7 lobes that are also individually shallowly lobed. 

  • Flowers bloom from April/May to late July. It produces small pink flowers that are composed of 5 petals. 
  • Seed capsules look like a long beak, are ridged and tips will turn red when ripe. 


  • Reproduces by seeds that are ejected from the parent plant when ripe. 
  • Seeds are dispersed by wildlife, humans and on water passages. 

Habitat & Ecology

  • Shiny geranium grows in well-shaded woodlands and forest edges. 
  • Typically growing along side with another invasive, herb Robert (Geranim robertianum). 
  • Can also hybridize with other geraniums. 
  • Currently limited and found in the Greater Victoria Region. 



  • Dominates understorey ground cover and threatens species at risk. 
  • Emerges earlier than native species and can cover ground and take up resources quickly.
  • Crowds out native seedlings.  


Prevention is a high priority for this plant. 

  • Clean shoes, tools, clothing, pets and vehicles prior to leaving an infested site.
  • Help map and report this plant if you think you have seen it. 

Mechanical/Manual Contol: 

  • Small infestations can be removed by hand-pulling. Ensure to remove entire root systems. 
  • Larger patchs can be controlled by covering with sheet mulch using cardboard or woodchips to suppress growth. 
  • Monitor for several years as seed bank can presist after removal.
