Some wonderful moments at the Arnold Arboretum in 2017

Highlights from 2017_DirectorsBlog

2017 has been a magnificent year at the Arnold Arboretum of Harvard University. The trees, shrubs, and lianas dazzled, but of course, not in exactly the same way as in 2016, or for that matter, any other year since the dawn of time. To begin 2018, I share 12 moments from my wanderings in the […]

Summer Institute Participants Build a Plant From Bottom to Top

Teachers Mimic Tree Architecture

How is a tree put together and how does it grow? How do plants build cells out of thin air? How do those cells build discrete structures with specific functions? From August 21-24, 2017, twenty teachers of grades Pre-K through six, many of them classroom teachers and/or art, media, and several science specialists, came together […]

Aristotle, a solar eclipse, and the tortuosa European beech

Solar Eclipse_DirectorsBlog_Featured IMG

“Why, during eclipses of the Sun, if one makes observations of them through a sieve or through leaves (of a plane tree or another broad-leaved tree, for example) or by joining the fingers of one hand to those of the other, the beams become crescents on the ground?” So wrote Aristotle (perhaps), more than 2 millennia […]

A small grab bag of early August in the Arnold Arboretum

The lianoid Dutchman’s pipe (Aristolochia macrophylla, 43-92*C; left image), growing on the fence around the garage at the Hunnewell Building, is still putting out tender new leaves. The curve in the young stem tells the tale of a plant seeking out structures to curl around for support. The wonderful mass of buttonbush (Cephalanthus occidentalis var. […]

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 […]

Magnolia flowers fall apart beautifully

Magnolias Fall apart_Directors Blog_73_featured IMG

Things fall apart. That is the essence of a plant. I don’t mean the kind of falling apart of decay, but rather, the wonderful falling apart of the regular shedding of plant organs after they have served their given tasks. Bud scales after bud burst in the spring, petals after a flower is pollinated, leaves in […]

Wrap-up on spring flowering at the Arnold Arboretum

With temperatures regularly in the high 80s and into the 90s (F), spring is officially over at the Arnold Arboretum.  This was my seventh spring at the Arboretum and nothing in the past six years comes close.  Consistent cool and wet weather combined to allow almost every species to leaf out, flower and/or cone with […]
