The morning of her operation, my wife Rebekah decided that she wanted to bicycle to Faulkner Hospital, which stands little more than a mile from our neighborhood across the Arboretum. And so we packed up her overnight things and pedaled off toward Faulkner: through Bussey Brook Meadow, where frost whitened the relic reeds and the bare boles of Ailanthus creaked bonily in the breeze; onward up Valley Road, huffing and pedal-mashing past the magnolias still bare of their big leaves; and out through the Centre Street Gate, toward whatever was to come.

Ever since, passing this way triggers a welling of memory—my fear, her grit, and the shadowing trees. It seemed at the time as though cancer had declared war on our family: in quick succession, Rebekah, her sister, and my father were struck with diagnoses. Only Rebekah survived; she’s now fifteen years free of recurrence. I won’t say the trees made the difference, though I wouldn’t have wanted to face any of it without them.

After a recent surgery of my own, a morning walk in the Arboretum became my post-operative routine. The conifer collection was my special balm; as the days warmed and my stamina increased, I sought the secret chambers of the yews and the touch of the giant sequoia’s softly resonant bark. I wandered among the spruces crowded with new cones, releasing their pollen in cloudy sheets that sieved the sunlight as they drifted downslope. These gymnosperms, great survivors of life’s tumbling epochs, treasure hope and healing in their everlasting green. This medicine isn’t metaphorical: the air amid trees is vibrant with enlivened chemistry; their pigments tickle deep-rooted centers of neural appeasement; their fallen needles cushion every recuperative step. It’s a fast-acting pharmacopeia, with no unwanted side effects. I don’t believe it’s possible to overdose.

 Since those convalescent days I have treasured my walk to work, incorporating encounters with the collection into my commute. A long-dormant case of sciatica recurred over the summer, however, taking away my walk with its wild, thickening pain. I tried describing it to a nurse who was contemplating a list of keywords: “it feels like I have an arrow buried in my back,” I said—“okay, that’s Stabbing,” she replied—“and there’s like a bare wire running down my leg”—“that would be Shooting,” she continued. “Shooting and stabbing?” I repeated. “I’m a crime scene!”

Keywords missing from the nurse’s form: Instability. Fragility. Hollowness. Uncertainty. Words for the psychic impact of pain, its cosmic extent—the way it narrows your mind, crowding out the questions that usually enliven you. Standing and walking brings out the worst of my pain, but sitting appeases it. This relief carries over into cycling, and so I’ve taken to biking again, a gift of miraculous, swift, pain-soothing mobility.

Yesterday, I set out on my bicycle for the oak collection. With a kindling curiosity about the history of Oklahoma’s oilfields, I was looking for specimens of blackjack oak, Quercus marilandica, a scrub oak found across the southeastern quarter of North America. Along the Texas-Oklahoma state line, it comes together with post oak and a wild variety of shrubs and other plants to form the “Cross Timbers,” a savanna ecosystem of great age and complexity interlacing the oilfields.

Heading out from Hunnewell along Meadow Road, I pedaled through the invisible patisserie of the katsuras still pumping out their caramel fragrance; turning at the ponds, I climbed Bussey Hill Road past the lemon-lime foliage of the redbuds ,under towering sassafras trees with mitten-shaped leaves, and turned down Valley Road past the bitternut afire with fall to its topmost height. Here I slowed, scanning for the particular blackjack specimens I sought.

The plant-record database lists twelve living trees distributed around the landscape, including one on Peters Hill that was accessioned in 1895. The specimens I sought in the oaks collection are younger, collected from the wild in 2018 by Tiffany Enzenbacher and Kea Woodruff during a collecting trip to Cross Timbers country near Tishomingo, Oklahoma. They’re saplings, only recently planted out, and still surrounded by protective cages of wire. Q. marilandica is sometimes called duck-foot oak, and I delighted at the comical webby footprint of the saplings’ still-green leaves, with which my imagination paddled off uncertainly toward the Great Plains.

And my pain? It hadn’t disappeared, but for a moment it felt right-sized on that vaster map. The analgesic effect of trees is compounded not only of chemistry, but curiosity.

Earlier, I said that it felt like cancer had declared war on my family. The metaphor feels fraught now, with the enormity of the war on Gaza growing daily. Recently, I received a pitch for an article from a young journalist proposing to write about West-Bank olive groves and the Palestinian farmers who tend them. I replied to his email, suggesting a January deadline. The day was Friday, October 6. A couple of days later, with the horrors of that weekend still emerging, he wrote again, asking for reprieve from the January deadline, with the hope that peace would come and he could return to the olive groves. I begged him to be safe. As I write this morning I see his byline from Tel Aviv, where he is covering the war.

Is there no balm in Gilead? the prophet cries in Jeremiah. Is there no physician there? Scholars believe the biblical balm was Storax, which Wikipedia describes as “a natural resin isolated from the wounded bark” of sweetgums. As for Gilead, it was a land that lay close by the River Jordan. We live in a world of wounds—and we share it with trees.

I expect the story of the olive groves will have changed by the time peace comes and the next normal is found (may it be soon). The malignancies of hate and fear, of war and unspeakable grief—I know that trees can’t take these away. I also know that there is no peace without them. Some of the West Bank olive trees are five hundred years old, after all. Think of all that those trees—and their caretakers in hope and in grief—have witnessed and withstood.

From “free” to “friend”…

Established in 1911 as the Bulletin of Popular InformationArnoldia has long been a definitive forum for conversations about temperate woody plants and their landscapes. In 2022, we rolled out a new vision for the magazine as a vigorous forum for tales of plant exploration, behind-the-scenes glimpses of botanical research, and deep dives into the history of gardens, landscapes, and science. The new Arnoldia includes poetry, visual art, and literary essays, following the human imagination wherever it entangles with trees.

It takes resources to gather and nurture these new voices, and we depend on the support of our member-subscribers to make it possible. But membership means more: by becoming a member of the Arnold Arboretum, you help to keep our collection vibrant and our research and educational mission active. Through the pages of Arnoldia, you can take part in the life of this free-to-all landscape whether you live next door or an ocean away.
