Felled by the wind

More than 20 large trees in the Arnold Arboretum came down or were severely damaged in the brutal Nor’easter on March 1, including several centenarians with important provenance. Most of the trees toppled by the winds had significant rot or underlying structural issues; it was only a matter of time. Like us, trees age, grow […]

A Tangled Tree

Yesterday, a genuine New England Nor’easter struck, with phenomenal winds and drenching rain, but fortunately for the trees, no snow. This storm brought to mind one of our old Japanese red pines (Pinus densiflora 16536*C), collected by Charles Sprague Sargent (first director of the Arnold Arboretum) in 1892 in Japan. It bears the scars of […]

Over the past few weeks, I have been repeatedly drawn to the North American oak collection on the southwest flank of Bussey Hill. There is something truly grand about this cathedral-like space, with soaring trunks and arched canopies meeting to create a magnificent vaulted ceiling overhead. You enter this architectural and botanical space and are set […]

Stop and smell the ginkgo seeds

When I look at these pictures, I can practically smell them! And my hope is that you will take my advice and go smell for yourself.

My favorite flower (this week)

GrewiaFlower_Directors Blog_73

One of the great delights of walking randomly in the Arnold Arboretum is the unanticipated discovery of a plant heretofore unnoticed. This week, Grewia biloba, a shrub I had never seen in flower, presented itself in full (but subtle) glory. The small white flowers with bright yellow eyes of stamens (pollen-producing structures) are stunning. What appear […]
