2021 Whatcom County Noxious Weed List
Prohibited Plant List
The Washington State Prohibited Plant List (PDF) contains the names of those plants for which it is illegal to transport, buy, sell, offer for sale, intentionally transplant or distribute plants or any plant parts within the State of Washington. This list is different from the Whatcom County Noxious Weed List and the Washington State Noxious Weed List. Several new weed species, including Italian Arum and Myrtle Spurge, have been added to the Prohibited Plant List in 2021.
