Final Season – 2018 Trees of Boston Calendar

The images for the 2018 Trees of Boston Calendar were all taken in the Arnold Arboretum, home to thousands of different plants from around the world.

Erik Gehring, the photographer, thanks the Arnold Arboretum of Harvard University for the use of its collection for this calendar. Five percent of net proceeds will be donated to the Friends of the Arboretum. Printed on 55% recycled paper (30% post-consumer waste) using vegetable-based inks. All photographs were taken in their respective months, and all are available as fine art prints.

This is the tenth and final edition of this project. The wall calendar is unfortunately a dying breed, and all good things must come to an end eventually. Thanks to all who have supported this project over the years. To order ($12 per calendar, $33 for 3, $50 for five, not including 6.25% MA sales tax or $2.50 shipping, visit
