Lichens grow on trees, shrubs and rocks in botanic gardens and can tell us about air quality and the make-up of plants and geology. Botanic gardens can take on new meaning as a *fun* place to observe a symbiotic organism made up of a fungus and algae. You will also learn about common lichens found in an urban environment and take home a user-friendly chart that lists lichens found in your neighborhood.
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!
