Thank you for submitting your report to the Oregon Invasive Species Hotline. The species that you reported is, Italian arum (Arum italicum), also known as Lords and Ladies. This plant is a plant that is well known for spreading into natural areas, and is very difficult to control. Italian Arum is certainly a difficult species to control, and effective control measures have not been identified for this species
Italian arum is not a state listed noxious weed, but is a weed of concern for the Portland Metro region. The cost to control weeds often exceed the resources available for this effort. As such, we must prioritize the species and areas we treat to maximize the benefits from our limited resources. Your report helps with this process, and allows us to plan future treatments as additional resources become available.
Once again thank you for your time and effort in reporting this species.
Sam
