Many different members of the Ericaceae, or heath family, thrive in New England’s acidic soils. This Arnold Arboretum class, offered with the New England Wild Flower Society and taking place at Garden in the Woods in Framingham on Tuesday, June 18, 9:30 – 12:30, begins with images and a description of the attributes of this family, including a demonstration of Go Botany to see the various genera. Along with botanist instructor Carol Govan, you will then walk outdoors to visit Garden in the Wood’s collection of azaleas, rhododendrons, blueberries, cranberries, leatherleaf, dog hobble, and more, also looking for evidence of nectar thieves and buzz pollination. Fee is $40 for Arboretum and NEWFS members, $48 for nonmembers. Register on line at www.my.arboretum.harvard.edu. Crowberries below courtesy of www.digitalnaturalhistory.com.
