Members of the Cornell’s Adult University course “Coffee, Cloves, and Chocolate: How Plants Have Shaped Human History,” taught by Don Rakow, took a field trip Friday to the Bluegrass Lane Turf and Landscape Research Facility adjacent to campus where research technician Kendra Hutchins gave them a tour of annual flower and foliage plant trials and other plantings. Earlier in the week, the class toured Gimme! Coffee’s roasting facility near Trumansburg.
