Description of specimen
Invasive plants starting in the green space behind our home.
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.
On the hill in the green space that goes down to a small creek behind our home. Spotted these brightly colored plants among the ferns, thought they were wildflowers and then discovered they are invasive. Behind 16558 SE Orchard View Lane, just north of Eckert Lane along the watershed where the Clackamas River Basin Council was due to remove invasive species before COVID-19.
