Featured Plants & Areas of Interest

This winter has been an easy one for shoveling and driving, and at the Arboretum, it continues in March, to be a great place to enjoy a healthy walk while observing the final weeks of leafless plants and the beauty in their elemental structure of bark and branch. It is still a good time to download our informative self-guided tour on Bark, then take a look on your own at what wonders winter provides visually. There are also flowers blooming that are ready to catch your eye, witch hazel and pussy willows are especially showy this year. Take advantage of open views to the further reaches of Boston and the surrounding areas from the summits of Bussey or Peters Hill. Peters Hill offers a spectacular vista over the conifers, all the way to the skyline of Boston. The Conifers themselves are green with texture and design. Before spring officially begins this month, take a look at our special Winter Tours brochure, with a map of various areas, as well as plant highlights, plant architecture, wildlife, and much more. It is available to be downloaded free or at the Visitor Center for a small suggested donation.

Tree of the Month

The March Tree of the Month is Salix gracilistyla var. melanostachys 2020 (black pussy willow). Black pussy willows get a lot of attention this time of year with their catkins, which resemble soft, fuzzy, black caterpillars. In fact the anthers on this pussy willow are deep, dark red rather than black, but they do make an amazing and unusual highlight along Meadow Road.  The Arboretum has ten pussy willow plants, all non-native, from countries including Japan, China, and Korea. The native pussy willow, Salix discolor does grow in the eastern United States but is not currently growing at the Arboretum.

Check out Arbexplorer to see where pussy willows are located.

Art at the Arboretum

The Path Taken
Photography by Lawrence Mullings
February 7 – April 26, 2020

Lawrence Mullings explores the paths and hidden corners of the Arboretum. His photographs are of those places, events, and visitors that we might miss ourselves. His images show that the Arboretum is trees, and much more–the visitors who absorb the spirit of the land while exploring their own personal quest or enjoying events. The Arboretum is a bridge to a new vista, a gift of dance to young girls, a tree for the respite and nourishment of a woodpecker. Many different people come here from around the neighborhood and around the world. Mullings finds them, and their pursuits, and brings to our exhibition the inspirational scenes he has captured along the “Paths” he has taken throughout the year. Lawrence Mullings is also an Arnold Arboretum docent who leads tours in our landscape.

As part of our Coronavirus (COVID-19) response, the Lecture Hall is currently closed and the exhibition is unavailable. View this exhibition online
