If you cannot identify the plant, take a photo home to ID it later.
You may practice at home before the mission using an internet search for images of the plants. Add the word leaf or bark in the search for the plant name.
King County also has a good website for native plants at https://green2.kingcounty.gov/GoNative/Index.aspx
You can also practice identifying plants in your neighborhood using a smartphone plant ID app like: Plant Net or Plant Snap. Take a plant photo in the app to ID it.
