  • Saturday, April 6, 10:00 am – 2:00 pm – Spring Pruning of Woody Ornamentals

    Spring is a great time to assess woody shrubs for shape, structure, and winter damage. This April 6 Berkshire Botanical Garden workshop will focus on learning by doing. Ron Yaple, owner of Race Mountain Tree Services in Sheffield, MA, will demonstrate how to renovate, rejuvenate, and shape shrubs and small ornamental trees for structure, health, and optimal growth. Plants covered will include viburnums, lilacs, witch hazels, deciduous azaleas, sweetshrubs, crab apples, and ornamental cherries. Participants should dress for the weather, bring pruners, work gloves, and a bag lunch. $25 for BBG members, $35 for nonmembers.

  • Thursday, September 15, 6:00 pm – Why So Many Leaf Forms? Insights from Viburnum Evolution

    Why do leaves come in such an extraordinary variety of shapes and sizes? Global patterns in the distribution of different leaf forms provide clues, and multiple hypotheses have been proposed to explain such diversity. Recent work on the evolution of Viburnum (a popular group of shrubs) complements studies of global patterns and adds a new hypothesis to the mix. Michael Donoghue, Sterling Professor of Ecology and Evolutionary Biology, Department of Ecology and Evolutionary Biology, Yale University, will discuss the Viburnum research, its relevance to understanding climate change, and the processes by which diverse ecosystems come into existence. The free lecture will take place Thursday, September 15 beginning at 6 pm.

    The Evolution Matters Lecture Series is supported by a generous gift from Drs. Herman and Joan Suit. This Harvard Museum of Natural History program is located at the Geological Lecture Hall, 24 Oxford Street. Free parking is available at the 52 Oxford Street Garage.
