Insects prefer yellow

DirectorsBlog_flowercolorchange_FEATURED

Every spring and summer, I keep an eye out for species whose flowers regularly change color, typically from yellow to red. This is especially evident among the buckeyes and horse-chestnuts (Aesculus) where just-opened flowers will have prominent splotches of yellow (to attract insect pollinators) that change to red (upper image; Aesculus turbinata, Japanese horsechestnut; 219-35*A) over the […]

Billions of buds are opening

Come. Now! There is an urgency to the explosion of billions of buds in the Arnold Arboretum right now. For the better part of a year, this growing season’s leaves and flowers have been encased in the dormant buds of every tree, shrub, and liana, waiting for the appropriate environmental signals to engorge with water, swell, […]

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 […]

The results are published in Nature Communications. more» abstract»

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 […]

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 […]
