The many kinds of goldenrods and asters are a visually striking and ubiquitous feature of our late summer and fall landscapes. However, since many of them look much alike, they can be a challenge to identify. This class, led by Ted Elliman,  will focus on the identification features and habitats of about 40 species of goldenrods and asters, looking closely at the characteristics that help to distinguish them in the field. Begin with a talk at BBG for an overview of these species and their identification features, followed by a field trip to a location rich in both asters and goldenrods to see many varieties in natural conditions. (Rain date for field day is Sunday, Sept. 8, from 11:30 a.m. to 3 p.m.)
