Through a power point presentation, a close look at herbarium specimens, and a foray into the field, this August 11 New England Wild Flower Society class will investigate the large and complex Polygonaceae family, whose many species in our region range in size from prostrate doorweeds (Polygonum aviculare) to the 12-foot giant knotweed (Fallopia sachalinensis), and grow in a wide range of habitats. In the field, we will look for and identify a number of upland and wetland species in the Fallopi, Persicari, and Polygonum genera. Taught be Ted Elliman, this class at Garden in the Woods will run from 10 – 4 and is $80 for NEWFS members, $96 for nonmembers.
