This week, I wandered the east side of Peters Hill, admiring the landscape, taking in long views of the collections of crabapples, pears, poplars, and ginkgoes. I dove into the deep understory darkness of the old dawn redwood grove down near the railroad tracks. I was dazzled by the extraordinary work of the Arnold Arboretum […]

The spectacle of spring flowering magnolias at the Arnold Arboretum of Harvard University is a show to see.

Right now, one of the Arnold […]

Goethe’s wonderful observations on redbuds were published in his Italian Journey (Italienische Reise), at a time when he was deeply immersed in reflecting upon art, antiquities, and plant form – and importantly, spending time in botanical gardens to decipher the underlying principles […]

Just a quick note for the continuing celebration of amazing buds bursting forth this past week at the Arnold Arboretum. The beeches are mostly finished (breaking bud), but Fagus orientalis (Oriental beech; 239-29-B) was impressive against the sun on Saturday: a combination of beautiful plications with shadows of overlapping leaves, along with bud scales and […]
