Monday, February 22, 7:00 pm – The Pecan: A History of America’s Native Nut, Online

This February 22 free Zoom talk at 7 pm Eastern is the first of three lectures in the Arnold Arboretum’s Director’s Lecture Series. Register at https://harvard.zoom.us/webinar/register/WN_kAicDT3WRwGwXUExDs4Oxg

In the United States, the pecan tree is native to a region stretching from central Texas to western Alabama, and from the Gulf of Mexico to southern Illinois. Today, most pecans grown for commercial consumption come from New Mexico and Georgia, places with no native pecans. What makes the extension of pecan production beyond its native habitat possible is the art and science of domestication. The pecan tree went from being primarily wild to primarily domesticated in an astonishingly quick period of time–a matter of decades. James McWilliams’ talk will explore the intricacies of this process while challenging us to think more critically about what we mean by ideas such as “natural,” “artificial,” and “authentic,” all of which are central to understanding the food we produce and consume.

Through Sunday, February 7 – If Winter Comes … The Promise of Each Year in the Paintings of Anthony Apesos

The Arnold Arboretum comes to life in Tony Apesos’s sensitive and expressive oil paintings. Working in his studio, he recaptures an essential essence derived from his frequent walks in the Arboretum. When elements of the landscape catch his eye, he interprets them with brush and spirit in accomplished works. His series of winter landscapes are especially vibrant, layered so finely that the cold and stillness of the land reverberate within the image.

Apesos is a professor at Lesley University College of Art and Design and has been extensively represented in solo and group exhibitions. He has received many honors, been included in numerous publications, and lectured widely. You can visit his website.

All rights of the images reside with the artist. For more information on making a copy, or reusing an image, please send your request to arbweb@arnarb.harvard.edu

For information on the work itself, or to inquire about purchasing artwork, please also send your requests to arbweb@arnarb.harvard.edu We will put you in touch with the artist.

The Arnold Arboretum of Harvard University’s New Website

The Arnold Arboretum has just released an entirely new website, a fresh portal to the institution that has been two years in the making! Ned Friedman says: “We set out to create an online identity as evocative, welcoming, and revelatory as the collections and landscape themselves.  Over the next few weeks, we will introduce you to newly curated stories from the Arboretum including plant biographies, tales of plant exploration, scientific discoveries, and the institution’s multifaceted roles in promoting social and environmental justice. We will pull back the curtain to reveal some of the magic that lies behind our roughly 16,000 woody plants and 281 acres of Olmsted-designed landscape. Today I’m excited to share a new feature with you. “Walks” offer virtual tours of the Living Collections, curated and designed by our staff, including me. The Director’s Tour illuminates just a few of the thousands of plants I’ve photographed and been captivated by over the past decade. Join me to find out why I love snakebark maples (and why you should too), why inhaling putrid ginkgo seeds is vivifying, and why I worship the acorns of the Oriental oak. And when you next visit, make your way to these very plants to experience their charms through the seasons in person. ” Very exciting news indeed.

Inspired By Nature: Five Printmakers at the Arnold Arboretum Online Exhibition Through July 19

Please note that all exhibitions are suspended due to the closure of the Hunnewell Building and Visitor Center as part of Harvard University’s COVID-19 response. See our current art exhibition online.

When our Visitor Center reopens, on site-exhibitions will resume and continue to be free and open to the public in the Hunnewell Building at 125 Arborway, Boston.

For five printmakers, sketching trips to the Arnold Arboretum solidified what they already had in common—the many ways that nature and plant life informs their art. Although their media covers a wide range of print techniques, and each artist has a unique approach to their art, all are attracted to the natural world, often trees. From white line woodcut to monotype, a keen sensibility of botanical life emerges that is portrayed through the eye and craft of these artists.

Printmakers Arlene Bandes, Lynda Goldberg, Mary Beth Maisel, Amy McGregor-Radin, and Gayle Smalley have been meeting monthly for more than ten years to discuss works in progress. They critique, support, and challenge each other to explore beyond the limits of their art. Ideas, sketches, and current prints are shared. There is a commonality that emerges in the art exhibited in this show of homing into the essence of nature.

Each artist is an active member of the Nature Printing Society, an international association of artists whose philosophy is based on respect for nature as demonstrated through the art of the print. Members have exhibited in numerous galleries and museums including Attleboro Art Museum, The Art Complex Museum (Duxbury), The Boston Athenaeum, and the Fuller Museum of Art (now Fuller Craft Museum), among others. Maisel and Goldberg contributed chapters to The Art of Printing from Nature, published by the Nature Printing Society. Goldberg and Bandes are instructors in the Greater Boston area. For more information on this exhibition or individual works, please contact arbweb@arnarb.harvard.edu. See a post on ARBlog to learn how this show was affected by, and was adapted to COVID-19.

Thursday, June 4, 2:00 pm – 2:30 pm – Painting Edo

“Painting Edo” at the Arnold Arboretum is a collaboration between the Arnold Arboretum of Harvard University and the Harvard Art Museums, inspired by the exhibition Painting Edo: Japanese Art from the Feinberg Collection.Observing artworks from the exhibition alongside the living collections of the Arnold Arboretum, we invite you to marvel at the remarkable accuracy with which artists of the Edo period (1615–1868) in Japan rendered their botanical subjects.  In this online talk, Rachel Saunders, Abby Aldrich Rockefeller Curator of Asian Art, and William (Ned) Friedman, Director of the Arnold Arboretum, will discuss the striking Magnolia sieboldii, also known as Siebold’s magnolia or the Oyama magnolia. After a close look at a very rare painted specimen in the Feinberg Collection with Rachel, Ned will bring us into the Arboretum’s landscape to learn about the live specimen’s unique biology and gorgeous bloom.  
This virtual program will take place live in Zoom. Free admission, but registration is required. Rain date Friday, June 5. Register here: https://harvard.zoom.us/webinar/register/WN_Frp8sRcWTqG1S_aZKI7gZg
