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 […]

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, […]

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 […]
