If wildflowers lead the brigade of popular plants, then the least popular plant, poison oak, also deserves mention. This species is most common in dry, sunny places, but it can also be found in denser forests. You should be especially wary of this rash-producing menace when you are hiking in the eastern Columbia River Gorge. Poison oak comes in a variety of forms, sometimes growing as a vine and sometimes as a low bush, but it always has lobed, often shiny leaves, that grow in groups of three. Hikers who travel with the family pet need to remember that, no matter how smart you think Rover is, he probably isn’t bright enough to recognize and avoid poison oak. Many unsuspecting pet owners have picked up a nasty rash from merely petting their dog after a hike in poison-oak country.
