Description
“My Botanical Life with Hemlocks” traces Harvard research scientist and botanist Peter Del Tredici's original research on hemlock trees (genus Tsuga) at the Arnold Arboretum over the past 40 years. Peter has been studying hemlock trees since 1981 and his research has covered such topics as the history of Sargent’s weeping hemlock (1983); the immunity of the Chinese hemlock (Tsuga chinensis) to the hemlock woolly adelgid (HWA) (2004); and the description of a newly described Korean hemlock species, Tsuga ulleungensis (2017). The UT Arboretum is home to a special weeping hemlock specimen which is over 80 years old. Join us as we explore the hemlock family and the genus Tsuga! The program will be recorded and sent to everyone who registers. Closed captions will be available.
Our presenter is Peter Del Tredici. Peter's botanical career started in 1972 as a technician running the research greenhouses at the Harvard Forest in Petersham, Massachusetts where he studied nitrogen-fixation in non-leguminous plants. In 1979, he started working at the Arnold Arboretum of Harvard University in Boston and continued there until his retirement in 2014. During those 35 years, Del Tredici served as the Assistant Plant Propagator, Curator of the Larz Anderson Bonsai Collection, Editor of Arnoldia, Director of Living Collections, and Senior Research Scientist.
Peter's research interests are wide ranging and include subjects such as the trees and shrubs of temperate China, the root systems of woody plants, the botany and horticulture of magnolias, stewartias and hemlocks, and the natural and cultural history of the Ginkgo tree. Since 2004, his work has focused on urban ecology and climate change.
Del Tredici was also an Associate Professor in Practice in the Landscape Architecture Department at the Harvard Graduate School of Design from 1992 through 2016 where he taught a range of courses from plant identification to soils to urban ecology and climate change. From 2016 through 2019, He taught in the Department of Urban Studies and Planning (DUSP) at MIT. In 2013, Peter was awarded the prestigious Veitch Gold Medal by The Royal Horticultural Society (England) “in recognition of services given in the advancement of the science and practice of horticulture.”
