Arboretum Lichens (in-person)

Lichens are harmless to your plants and add aesthetic value to trees and shrubs. We can actually use them as indicators of air pollution! Join Dr. Katherine Glew at the Washington Park Arboretum to get a head start on learning lichens from one of Seattle’s botanic gardens. You can enjoy the late winter/early spring season by looking for lichens, rather than staying inside and missing out on the excitement of being outside!
