Tree IdentificationMay 7, 2009 at 6–9 p.m.

Can you tell a mountain ash from a green ash or a balsam fir from a white spruce? These classes, led by Cindy Johnson-Groh, Executive Director of the Linnaeus Arboretum at Gustavus Adolphus College, will help you learn to identify the common trees in southern Minnesota. No prior experience with plant identification is necessary. Participants should be dressed to be outside.
