At the base of Hemlock Hill, hugging Bussey Brook, are a series of large eastern hemlock trees, Tsuga canadensis (map). As always, their deep shade is welcome on a hot summer day. Carefully step into the understory and look down. You will see clusters of small white to pinkish shoots (upper images) emerging from the […]
Un misterio persiguió a Darwin hasta sus últimos días. ¿Cómo habían surgido las flores? ¿Cómo se habían dispersado y diversificado tan rápido? ¿La naturaleza daba saltos? De ser así toda su teoría podía estar en peligro. Esto y muchas otras cosas sobre ese “misterio abominable” lo podéis encontrar en el artículo basado en el trabajo de William Friedman.

My father often fly-fishes there, casting for the brook trout that sway beneath the rapids. When the Arboretum’s mountain laurels explode with flowers […]

Young spruce cones, like most conifer cones when they are flushed from a bud, are dramatic shades of red, purple, pink, and even yellow. If this seems surprising, given how often you […]
At Weld Hill, the Arboretum is constructing its third and largest solar project, with nearly 1,300 solar panels bringing renewable energy to its advanced research and teaching facility. Read more in the Harvard Gazette
Early spring flowering is well underway at the Arnold Arboretum. Of special note today, are those wind-pollinated species whose flowers are essentially reduced to little more than the structures that produce pollen or seeds (no need for showy petals to attract pollinators). Among temperate woody plants, these early spring wind-pollinated taxa typically have unisexual flowers, […]

Awarded by the National Tropical Botanical Garden (NTBG), the Fairchild Medal was presented to Dosmann […]
Full moon, clear sky, trees, ice, lunar eclipse. A magnificent recipe! Yesterday, after an erratic mixture of snow, sleet, and rain, temperatures plummeted here in New England, leaving each and every tree ensheathed in a thick coat of ice. The full moon, followed by a total lunar eclipse set the stage in the woods behind […]
