Great Trees www.morrisarboretum.org/gardens-trees/great-trees

Great Trees Great Trees Image Image One of the most admired features of the Morris Arboretum & Gardens is its collection of large and beautiful trees. When John and Lydia Morris first purchased the property in 1887, it was virtually devoid of trees. They soon launched into an intense tree-planting program and under careful nurturing, these trees have grown into the beautiful specimens for which the Morris is well known today. Great Trees Highlights Image Dawn-redwood Metasequoia glyptostroboides A fast-growing tree with a majestic  habit, golden fall color, reddish brown  bark – fissured and exfoliating in long narrow strips – and a spectacular buttressing fluted trunk. This beautiful grove, now over 100 feet tall, was planted in ideal conditions – full sun and next to a stream that provides moisture. Once thought to have been extinct, these trees from the end of the dinosaur age were rediscovered in China through the study of fossils in the 1940s. Image Ginkgo, maidenhair-tree Ginkgo biloba One of the world’s oldest tree species, growing on earth for well over 150 million years. With striking gold fall color, this female  specimen, planted by the Morrises,  has messy and very smelly fruit. Non-fruiting males make excellent city trees. A male specimen is near the Edith Bogue magnolia Image Weeping European beech Fagus sylvatica f. pendula Native to Europe, planted before 1909 by the Morrises. Branches weep down and form roots where they touch the ground. New rings of trees grow outward as the original tree ages and dies. An impressive tree in all seasons with its smooth gray elephant hide-like bark, lustrous green leaves in summer, and red to golden brown fall color. Small holes in trunk are made by sap sucking birds. Image Blue Atlas cedar Cedrus atlantica ‘Glauca’ The straight species is native to the Atlas Mountains of North Africa. Layered branches with blue-green needles create a picturesque landscape tree. Small finger-shaped male cones on lower branches …

The Roots of American Botany: Vignettes from Philadelphia’s Scientific Past

Thursday, April 23
10:30 am
Virtual
Registration is required
REGISTER

Philadelphia is not only the birthplace of America; it is the birthplace of American botany. Widely celebrated as “America’s Garden Capital,” the city has also played a pivotal role in shaping the nation’s understanding of plant sciences. Join us for a lively virtual discussion exploring Philadelphia’s rich botanical legacy through compelling stories of the past and examples of cutting-edge research tools Morris Arboretum & Gardens scientists as well as other members of the Penn research community are using to solve enduring botanical mysteries. Highlights include new research initiatives at Morris, an exploration of the genetics of Penn’s historic Penn Treaty Elm, and collaborative work in plant genetics with the Penn Museum. Free with registration.

Dr. Morgan Gostel
John J. Willaman Director of Plant Science, Morris Arboretum & Gardens

Dr. Morgan Gostel is the John J. Willaman Director of Plant Science at the Morris Arboretum & Gardens of the University of Pennsylvania. His research in plant systematics emphasizes diversity and evolution of what he refers to as his botanical A, B, Cs, namely three families of flowering plants including Araliaceae (ginseng and ivy), Burseraceae (frankincense and myrrh), and Compositae (daisies and sunflowers). His work has especially been focused in tropical Africa and Madagascar, but the plants in these families are distributed worldwide. Dr. Gostel is also a Research Associate in the Department of Botany at the Smithsonian Institution’s National Museum of Natural History and the Botanical Research Institute of Texas at the Fort Worth Botanic Garden. Since 2015, he has led the Global Genome Initiative for Gardens (GGI-Gardens), an international partnership of botanic gardens dedicated to supporting the collection of genome-quality tissues from living collections to support genomics research.

Chantel White is the Teaching Specialist for Archaeobotany in the Center for the Analysis of Archaeological Materials (CAAM) at the Penn Museum. She is also a Senior Lecturer in the Department of Anthropology in the School of Arts and Sciences. Her research focuses on the study of plant remains from the Near East, Mediterranean, and historical North America across a diverse set of archaeological sites ranging from the Upper Paleolithic (40,000 years ago) to the recent past (19th century). The shared goal of these studies is the reconstruction of everyday life, particularly the identification of activities related to the storage, preparation, and consumption of foods.

Hannah Anderson is an Assistant Professor of History at the University of Arkansas at Little Rock. Previously, she was the University College Fellow of Early American History at the University of Toronto. She holds a Ph.D. from the University of Pennsylvania. Her book manuscript, Lived Botany: Settlers and Natural History in the Early British Atlantic, examines how settlers exchanged botanical knowledge with Indigenous and African people and argues that these interactions shaped the development of the science of natural history and the fate of England’s Atlantic empire. Dr. Anderson’s work has been supported by many institutions. Most recently, she was a Dibner Long-Term Research Fellow in the History of Science and Technology at the Huntington Library. In the past, she has also received support from the McNeil Center for Early American Studies, the American Philosophical Society, the Consortium for the History of Science, Technology, and Medicine, the John Carter Brown Library, the American Antiquarian Society, the Library Company of Philadelphia, and the New England Regional Fellowship Consortium.

Friends for Years, Now Volunteers at Garden Railway www.morrisarboretum.org/blog/friends-years-now-volunteers-garden-railway

Friends for Years, Now Volunteers at Garden Railway Longtime friends Jon Perlman and Howard Greenberg volunteer together at the Garden Railway —  a joyful extension of decades of friendship, shared hobbies, and gentle ribbing. When longtime friends Jon Perlman and Howard Greenberg put on their matching engineer hats and red bandannas to tend to the miniature marvels of the Morris Arboretum & Gardens' Garden Railway, it’s more than just volunteer work—it’s a joyful extension of decades of friendship, shared hobbies, and gentle ribbing. What started with a nudge from Perlman’s wife has turned into a weekly routine for the two retirees, who now spend one morning a week maintaining the tracks, organizing equipment, and enjoying each other’s company. Image Jon Perlman gently places a train car on the track at the Garden Railway, one of the many jobs of a volunteer. Two years ago, Bette Perlman, a volunteer of nearly three decades at the Morris, saw a notice about a tour of the beloved Garden Railway. “And she says, ‘Jon, you might be interested in that,’” he said. Why did she think he’d be interested? “Because we’ve been married for long enough, so she knows,” he said. This year, Perlman invited his newly retired friend, Howard Greenberg, to join him. “I was looking for something to do,” Greenberg said. “I retired December 31. I've been a lawyer for 51 years, and decided I need to get out of the house. So I did.” “Actually, he didn't decide to get out of the house,” Perlman retorted. “His wife decided he should get out of the house.” Bette and Howard’s wife, Emily, were college roommates, and their husbands have been friends for many years. “When I brought the grandkids here years ago, I thought it was amazing,” Greenberg said. “And now you’re working on it,” I teased. “I’m working on the railroad.” “Not all the live-long day, just in the morning,” Perlman said, referencing the old American folk song . KEEPING BUSY Both men grew up with train sets in their homes. …
