I enjoy taking walks, and currently, my favorite route is a cemetery path in the town where I live. I like the cemetery for a number of reasons; one of them is the trees. I always say that it has the best trees in town—mostly tall, straight-trunked pin oaks and gnarly-branched bur oaks, but also scattered basswoods and hackberries, a row of pines, and at least one old cedar. Despite their appeal, the trees aren’t the only graveyard vegetation catching my eye this summer. Alon
