| Geranium robertianum poses a threat to forest understories and plant biodiversity by displacing native species, especially herbaceous species. In preliminary research in western Washington it was found that under 90 percent canopy cover it was possible to find 250 plants/m2. In a more open canopy (e.g., 50-60 percent) there were only 112 plants/m2 but these plants were larger and more vigorous. There are unsubstantiated reports that its strong odor may trigger asthma attacks (Tisch 1992). Beneficial: Herb Robert is an ornamental species and has been sold in nurseries in the Pacific Northwest and elsewhere. White flowered forms are also sold. It has a long history of medicinal use including relief from toothaches and nosebleeds (Bath and Jones 1994). | Geranium robertianum poses a threat to forest understories and plant biodiversity by displacing native species, especially herbaceous species.
