Contemporary of the Dinosaurs: Cathay Silver Fir This spring, the Morris added an extremely rare plant to our collection: the Cathay silver fir, Cathaya argyrophylla, an ancient member of the pine family, and a “living fossil" that first appeared in fossil records around 140 million years ago during the Cretaceous period of the late Mesozoic Era.   Image The Cathay silver fir, Cathaya argyrophylla, is located to the left of the Key Fountain and across from the dawn-redwoods in English Park. The Morris possesses a collection of trees and shrubs that encompass everything from the exotic to the common,  the ornamental to the esoteric. This spring we were fortunate to add another extremely rare plant to our collection. The Cathay silver fir, Cathaya argyrophylla, is an ancient member of the pine family, and a “living fossil.” It first appeared in fossil records around 140 million years ago during the Cretaceous period of the late Mesozoic Era. It was a contemporary of the dinosaurs that roamed the earth during this same time. The Cathay silver fir was thought to be as extinct as the dinosaurs who ate it. In 1938, Professor Yang Hsien-chin from Fudan University was doing fieldwork on the remote Golden Buddha Mountain in southeastern China when he discovered an unknown conifer. He took herbarium specimens from his mysterious find back to his lab for further study. Unfortunately, due to a variety of factors (not the least of which was the outbreak of a global war), his herbarium voucher sat uninvestigated. In 1949, the newly installed Chinese Communist Party created the Institute of Botany and folded Professor Yang’s specimen into a national herbarium collection. Here his herbarium vouchers languished in further obscurity as an unidentified tree. In the summer of 1955, in another remote forest near the Golden Buddha Mountain, several Chinese botanists discovered conifers they did not recognize. They sent specimens of these plants to the Institute of Botany. Using …

Private Estate 1887-1932 Private Estate 1887-1932 Image Collections: Private Estate Era, 1887–1932 Morris Arboretum of the University of Pennsylvania Records Morris Arboretum was originally the private estate of John Thompson Morris (1847-1915) and his sister Lydia Thompson Morris (1849-1932). John and Lydia established the estate in 1887 with the purchase of 67 acres in Chestnut Hill, which they named Compton. Their Gothic Revival style mansion and carriage house, designed by Theophilus P. Chandler, Jr., were constructed the following year. In subsequent years, they built a large greenhouse complex near the banks of the Wissahickon River, including a Fernery, Palm House, potting shed and hotbeds. Over the next quarter century, John and Lydia Morris purchased several contiguous properties and enhanced the grounds with classic European and Japanese gardens, picturesque garden follies, fountains, ponds and pergolas. Between 1881 and 1910, the Morrises went on eight extended trips overseas and attended seven international expositions. On their travels, they purchased antiquities and objet d’art to furnish the mansion and donate to Philadelphia institutions. In addition to creating beautiful pleasure gardens for their own enjoyment, John and Lydia amassed an extensive collection of tree and shrub families and genera from around the world, with the goal of establishing botanical gardens “conducted on scientific principles.” Their goal was realized after John’s death when Lydia bequeathed Compton and Bloomfield to the University of Pennsylvania.

Public Garden - After 1974 Public Garden - After 1974 Image Collections: Public Garden — After 1974 Morris Arboretum of the University of Pennsylvania Records The 1970s was a time of considerable change for the Arboretum, set in motion when Dr. F. Otto Haas assumed the position of Chair of the Advisory Board in 1972. During his tenure as Chair, the University granted the Arboretum more freedom as a university-wide “Resource Center” and the Board began to play a more active role. In 1977, Dr. William M. Klein, Jr., an experienced botanical garden administrator, was named the Arboretum’s first full-time Director. Eight months after his Image Planning the Arboretum: Director William Klein with Colin and Carole Franklin of Andropogon Association, 1976. appointment, Dr. Klein and the Board, under the guidance of Dr. Haas, launched a comprehensive renewal program in tandem with the University’s institution-wide plan for the 1980s. The stated goal of the renewal program was to “renew and endow the Arboretum’s most precious assets and to develop a standard of excellence for those features that are fundamental to its original design and purpose as a university and public institution, as set forth by Lydia T. Morris in 1932” ( Morris Arboretum Newsletter , March-April 1978). One of the operational changes at the Arboretum was assigning horticultural staff to specific areas of responsibility rather than serving on roving crews across the entire grounds—a plan still being implemented today. Another change, led by then-Curator Paul Meyer, was implementation of a comprehensive policy for collection of shrubs and trees, also still being implemented. A third change was increased emphasis on educational programs utilizing the resources of the Arboretum. By the end of the 1970s, the Arboretum had taken the significant steps toward renewal, with the support of grants and in partnership with the landscape planning firm, Andropogon Associates. This partnership has continued with …

Exuberant Blooms is Bigger, Bolder, and Brighter Hot, bold colors dominate this year's Victorian-inspired exhibition!  Image Our annual modern take on Victorian flower carpets, Exuberant Blooms , is even HOTTER this summer with eight beds of bigger, bolder, brighter, and more beautiful flowers! Spread over more than a quarter acre of open garden, the large paisley-shaped floral “islands” contain more than 10,000 plants with heights ranging from 8 inches to 8 feet. Hot colors dominate this year’s exhibition with a wide variety of annual and tropical plants of vibrant orange, pink, red, and purple flowers all vying for attention. And while there will be new and interesting foliage for visitors to admire, we are also bringing back many of your plant favorites from last year. The color, shape, and scent of each flower not only catches our gaze but also attracts pollinators—insects and birds in search of the flower’s nectar or pollen, including lots of butterflies and hummingbirds! These animals are called pollinators because they carry pollen from the male part of the flower (stamen) to the female part of the same or another flower (stigma).

Digging into Native Plant Research Native plants, trees, and shrubs play a critical role in maintaining the health and stability of Pennsylvania’s ecosystem—and the Morris has been at the forefront of native plant research for nearly a century. Native plants are imperative to our ecosystem, contributing to cleaner air and water, healthier soil, climate regulation, and a welcoming habitat for wildlife. “We don’t take a breath that isn’t supported by native plants,” says Timothy Block, PhD, the John J. Willaman Chair of Botany and Director of Plant Science at the Morris Arboretum & Gardens. The University of Pennsylvania has published the story "Digging into Native Plant Research," which highlights the importance of native plants and the recently established Jan Albaum and Harry Cerino Native Plant Research Endowment in Memory of Martin Albaum. This endowment will support our Plant Science Department as well as the Morris Arboretum & Gardens Plant Science Lab, which will focus on regionally rare plant species and forest health. The lab is set to break ground this fall, and will be located on the Bloomfield Farm side of the Morris.
