The Japanese butterbur is an invasive weed that is slowly spreading through Portland’s natural areas.
It looks like a tropical plant, with large, thick green leaves that can reach up to four feet wide. The leaves’ underside is fuzzy, and the weed can grow to be six feet tall.
Invasive species damage forests, streams, rivers, and personal gardens. Controlling invasive weeds (and fixing the damage they cause) costs Oregonians $125 million each year. It’s important to catch invasive weeds before they become dangerous infestations.
If you find Japanese butterbur, please contact Dominic Maze (firstname.lastname@example.org) at the Bureau of Environmental Services to discuss control options.
