My Botanical Life With Hemlocks with Peter Del Tredici
Register for the Zoom Link and Recording
Thursday, September 25, 7pm EDT on Zoom
“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.”

Art in the Arboretum: Botanical Printing Workshop with Jan Quarles
SOLD OUT
Register to Reserve a Spot: Class Limit is 10
Saturday, September 13, 9am -4pm EDT
Join us at the UT Arboretum for a full day botanical printing workshop on Saturday, September 13 from 9am -4pm. Did you know many leaves and flowers will share colors and create beautiful natural prints on fabric? Botanical printer Jan Quarles will teach a workshop on the basics of this amazing process during our Art in the Arboretum fall event. Workshop participants will make and take home two scarves of their own design!
Due to the hands-on instruction, the class is limited to 10 participants. *The fee is $140 which covers instruction and all materials including the two silk scarves that each participant will print and take home! Registration with payment is required to reserve your spot in the class. The class is for ages 16 and up. UT Arboretum Society members receive a 15% discount on registration. One scholarship is available for a high school or college student to participate in the class. Contact Michelle Campanis, UT Arboretum Education Coordinator at mcampani@utk.edu. Please wear clothes you don’t mind getting dirty!
Students will learn how to choose plants that transfer their color and prints well. Each student will make two beautiful silk scarves by placing plants (leaves and flowers) for a design on a prepared fabric. They will then then roll, dye, and steam the fabric in a layered technique for beautiful prints. Work will be done with two prepared scarves – one with eucalyptus that turns an amazing red and another with materials provided by the Arboretum.
*Minimum of 4 attendees for class to be held.
Our instructor, Jan Quarles, is a long-time fiber artist who works with the beauty of the natural world. For more than 30 years she’s been a dyer, weaver, knitter, seamstress, and spinner. Today, with her small business, What Nature Leaves, she is a botanical printer who marries natural dyes with nature’s leaves and flowers to document colors and seasons.
She’s also an indigo dyer and practitioner of shibori and katazome who deeply loves the magic of indigo and layers the blues with other natural dyes in her botanical practice. Quarles had a solo show of her indigo and botanical prints in Nashville in 2022. She has a botanically printed flag in an international show and has studied with many teachers at Arrowmont, Penland and other craft venues nationally and internationally. She is a former journalist and professor of mass communication in the United States and overseas who has always practiced her fiber arts in the hours that were her own.
