Native and Naturalized
Woody Plants of Oregon

         Woody plants that are native to, or naturalized in, Oregon are listed below in alphabetical order by their "scientific names" (their Latin binomials), more or less according to their height, ranging from large trees to low growing ground covers.  Naturalized plants refer to those plants that are not indigenous to Oregon but were introduced into the State and have become widely established in natural areas.  Many such plants are considered invasive, since they frequently damage natural areas by altering ecosystem processes, in part, through the displacement of, or hybridization with, native plants.
