Remedy

Italian arum can be difficult to eradicate once established. Make sure to wear gloves and long sleeves and pants when removing it, as its sap can cause skin irritation. Do not compost or put in your yard debris, as this can lead to spreading of tubers which can grow into new plants. Home control methods can include carefully digging out the tuber and any daughter tubers and disposing in the trash. Cutting and disposing of the berries in the trash can help prevent spreading to new sites. Herbicide trials are still inconclusive, please contact your local Soil and Water Conservation District if you are interested in chemical control.

Location

Just to the north of the path that goes from the NE Century Blvd Entrance into Noble Woods Park. I had reported seeing Italium Arum at this location earlier this year in this report: https://oregoninvasiveshotline.org/reports/detail/6880 I noticed a few months after I reported it that someone had come along and cleaned up the arum, however yesterday 8/18/25 I noticed a few plants that were left that now have orange berries.
