The Arboretum is my favorite place in Boston, for walking, thinking, listening and seeing. I adore trees, but I also love the idea of their invisible symbiotic relationships with fungi and mycelia interacting beneath my feet. I’m fascinated by the subliminal workings of my senses and the underlying structures of all living things. John Berger emphasized that “the relation between what we see and what we know is never settled.” Trees hold time and time represents memory; so the Arboretum’s trees have “seen,” “heard” and “felt” deep time. When wandering around the park, I feel time and space compressed into the living collection; I imagine the flow of chemicals and nutrients, the “heartbeats” of solid arboreal shapes, the birds and insects that inhabit and visit them, the relationships between micro and macro patterns across living systems, similar to our own bodies and the symbiotic “beingness” of ourselves in relational reciprocity with trees, and theirs with their mycorrhizal networks.
