Ghosts and Goblins in a cemetery for Hallowe’en?

Why not consider lichens as an alternative?  Lichens are friendly and interesting organisms that love to grow on headstones and old trees.  Cemeteries 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.

Always wondered about what lichens are and why they are found on your trees and Rhododendrons?  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 and the Center for Urban Horticulture on Saturday, October 27 to get a head start on learning lichens from your local cemetery.  You can enjoy Hallowe’en looking for lichens rather that scary witches and pumpkin heads.

Cost: $25; $30 after October 24.
