Sprout Lands: Tending the Endless Gift of Trees

William Bryant Logan, Certified Arborist, Founder and President of Urban Arborists, Inc., and Author

Thursday, June 27, 6:30–7:45pm
Arnold Arboretum, Hunnewell Building

When his company was asked to pollard trees in front of the Metropolitan Museum of Art in New York City, William Bryant Logan was stymied. This prompted him to research and learn this ancient way of pruning that prompts thick nests of sprouts to form on major branches. The irony here is that pollarding (and the similar practice of coppicing) had been the preeminent way in which humans had tended trees–from the last ice age to the Industrial Revolution. What would have seemed the most mundane of tasks to a villager in the Middle Ages had slipped from use, and even memory, in the twenty first century. Hear Logan speak of the many ways in which these lost ancient arts (including pruning, hazel creating living hedges, growing oak for ships) created and supported human cultures all over the world and how we once lived closely as partners with trees, as we can only hope to do again.

The Art of Botanical Prose

Jonathan Damery, Associate Editor of Arnoldia, Arnold Arboretum

1 Session: Tuesday, June 25, 7:00–8:15pm
Location: Hunnewell Building, Arnold Arboretum

All writers must contend with translation. A poet translates the movement of a dancing figure into a brief couplet, and an essayist translates the noise and commotion of the city where she lives into a single paragraph. The three-dimensional world filters into text, and when done especially well—the realm of literature and art—readers often forget that translation has even occurred. In this talk, Jonathan Damery, the associate editor for Arnoldia, will provide a readerly tour through horticultural and botanical reference books, encouraging readers to see the artistic endeavor within even the most exhaustive of botanical descriptions. Fee $5 member, $10 nonmember
