The Arboretum in September

On the cusp of fall, look for early signs of the changing season.

The first tree to show fall color is the Schlesinger maple, Acer rubrum ‘Schlesingeri.’ Another delightful early sign of fall is the magically burnt sugar scent of Katsura trees (Cercidiphyllum japonicum) as the leaves reach the end of their life cycle. Don’t miss the fragrant seven-son flower (Heptacodium miconioides) that has started to bloom. Over the month of September, the calyces (collective term for sepals) do not fall off but persist and continue to grow. The fruits develop from flowers; light green at first, they ripen to a rose-purple. Use your phone and search on ArbExplorer to see if you can locate the Heptacodium miconioides that live in the Arboretum.

This month, our weekday tours resume with Monday and Thursday tours at 10:30am. Interpreters will also be back in the landscape on select weekend days from 1:00-3:00pm. Saturday and Sunday tours continue to be available through November 1. Check out a special guided theme tour – From Seed to Tree (greenhouse tour), or a Fall Bird Walk.

Join knowledgeable volunteers for a look inside the Bonsai & Penjing Pavilion each Thursday in September from 11am – 1pm.

Water – and Climate – Solutions in Plain Sight will focus on reframing our global environmental challenges in a way that illuminates potential solutions.  For once we broaden our perspective to include how water moves across the landscape and through the atmosphere, we’ll find many opportunities to restore ecological cycles, even entire ecosystems. Judith Schwartz will offer examples from around the world that she’s encountered in her reporting for her newest book, Water in Plain Sight: Hope for a Thirsty World.

View our exhibition, New England Society of Botanical Artists: The Art of Woody Plants, which will be on display in the Hunnewell Lecture Hall through October 11th.

All art shows are free and open to the public. The Lecture Hall is also used for lectures, programs, meetings, and school groups, so please call 617.384.5209 for exhibition availability.

The Visitor Center and Art Exhibitions are open 10:00am–5:00pm, closed Wednesdays.

Please see our calendar for a great list of lectures, classes, and tour opportunities in September.
