I learned a lot in my first class in 1975. Some classes were given at the Arboretum, and others at the instructor’s residence in Newton. Later that year I was stunned to receive in the mail a French lilac, as a Member Benefit. When I moved away from the Boston area I considered which of my friends had the most stable marriage. I root-pruned the lilac, and in the fall gave it to those friends in Lincoln, MA. It thrives to this day.
