Oregon Native Plant list

Highlights of the Portland Plant List

• The Native Plant Lists provide information about associated habitats, flowering seasons, and whether some of these plants pose additional wildfire risk. Only plants from the Native Plant List may be planted in Environmental Overlay Zones and Pleasant Valley Natural Resource Overlay Zone resource areas. Native plants may be required in the Greenway Overlay Zones as well, and are encouraged throughout the city.

• The Nuisance Plant List includes ranks for each species that indicate how invasive or widespread the plant is in Portland. Plants on the Nuisance Plant List may not be included in any City-required landscaped areas or mitigation sites.

• The Portland Plant List also includes a new Required Eradication List of plants that must be removed. These plants are commonly found in Portland and must be eradicated if discovered to keep them from spreading.
