In this sculpture display in the Harvard Museum of Natural History’s Glass Flowers gallery, Scottish artist Siobhan Healy creates a subtle and thought-provoking piece inspired by the Ghost Orchid (Epipogium aphyllum), a rare British wild flower recently rediscovered after it was thought to be extinct for 23 years. Healy depicts the orchid in transient and ethereal clear glass, encouraging the viewer to reflect on the potential loss of this fragile speciesâ€”an evocative emblem of the one in five of wild flowers that are threatened with extinction. This artist talk will take place Friday, December 2, beginning at 4 pm. Free with museum admission. For more information, visit www.hmnh.harvard.edu.
