Since its inception as a public garden, the Morris Arboretum has served as a center for botanical research. Research staff at the arboretum study the evolution, phylogenetics, systematics/taxonomy, anatomy and morphology of plants. The Morris Arboretum also has a long-standing research program in floristics, or the study of what plants grow in a certain place in a particular time frame, with a major focus on the flora of Pennsylvania (please see below for details). We are currently fundraising to better equip our laboratory with a suite of molecular biology and anatomy/histology tools and equipment, to allow us to grow our research program even further. Please contact us at email@example.com with any questions about our research program, or if you are interested in becoming a volunteer or donor to help further our pursuits!
Early research staff of the Morris Arboretum included Dr. Rodney True, Dr. Edgar Wherry, and Dr. John Fogg. These and other scientists at the Arboretum have had considerable impact on the understanding of the flora of Pennsylvania and beyond. Today, The PA Flora Project's botanical research efforts focus on the occurrence of the native and naturalized plants that inhabit Pennsylvania. We recognize the importance of understanding the dynamic nature of the flora and seek to gain insights into these changes through work in the field, laboratory, and at the computer. We maintain the Pennsylvania Flora Database, a database of more than 400,000 plant records, to help store and disseminate the data we obtain in our research. We are currently working in collaboration with The Academy of Natural Sciences of Drexel University to further improve on the PA Flora Database by creating better access to plant specimens collected in PA through the PA Digitization Project, which will make high-resolution images of these specimens and the collecting information associated with them (i.e., who collected the plant, where and when) available online.
Achieving a greater scientific understanding of our urban areas, one plant specimen at a time
In light of the increasingly urban future of our planet, a thorough understanding of the biological processes at work in urban areas is necessary for the continued survival of Earth's inhabitants, including humans. The first step in that understanding is to know what thrives, survives, or perishes in cities, now and in the past. The Mid-Atlantic Megalopolis (MAM) Project begins this study by looking at vascular plants, with the digitization of roughly 700,000 herbarium specimens from eleven institutions in the urban corridor from New York City to Washington, D.C. As the largest, oldest, and most populated urban corridor in the U.S., this area and its flora present a unique opportunity for the study of urbanization, particularly given its rich herbarium collections, containing specimens collected over the last 400 years. The data mobilized in this effort will help us achieve a better scientific understanding of living urban systems, a critical need for urban planners, restoration ecologists, environmental engineers, (landscape) architects, and conservationists engaged in creating more sustainable and better designed cities, including the constructed and restored natural environments of our urban areas.
My research interests are in the flora of Pennsylvania and in GIS mapping of plant distribution.
My research is focused on the systematics and evolution of plants. I enjoy studying plants at many levels, from ecosystems to species to organs to genes. I am particularly interested in the floras of Pennsylvania and Madagascar, the digitization and dissemination of herbarium/floristics data, and the evolution of separate sexes in flowering plants.
The Flora of Pennsylvania Internship is a joint program between the Morris Arboretum of the University of Pennsylvania and The Academy of Natural Sciences of Drexel University. The Flora of Pennsylvania Intern receives training and work experience in many aspects of managing collections in a major herbarium, and an opportunity to contribute to a modern state flora through a research project on some aspect of the flora of Pennsylvania. This internship requires a dedication to building a professional career in botany. This position is supported by the Eli Kirk Price Endowment.
The Plant Protection Intern works independently, with supervision from the Arboretum's botanical and horticultural staff, to monitor plant pest and disease problems affecting the living collection. The intern also coordinates the Morris Arboretum Plant Clinic, which provides a forum for the public to ask pest, disease, identification, and other general plant questions. This position is supported by the John J. Willaman & Martha Haas Valentine Internship Endowment.
My research interests are focused on the floristics of Pennsylvania. I want to document the natural vegetation of the state and better understand historical and contemporary influences that have shaped the patterns of plant distribution we see today.
In response to the unprecedented public health crisis related to Coronavirus (COVID-19), Morris Arboretum will close to the public as of March 14, 2020 until the University of Pennsylvania feels that is it safe to re-open. Learn more about the Univerisity's response on the University of Pennsylvania’s dedicated Coronavirus website: coronavirus.upenn.edu. Please know that this decision was made after careful deliberation and that our priority is to do all we can to ensure the safety and well being of our staff, volunteers, and visitors. Information pertaining to public health is rapidly evolving and, as such, it is not yet known when we will reopen. We will be vigilant in our efforts to keep our website up-to-date and we will communicate directly to members and class registrants via email with the latest details.
The following information is provided in anticipation of some of the questions you may have relative to the following categories:
Individuals who have registered for a class
It is our intention to provide a refund to individuals who have registered for a class that occurs during this temporary closure. We are working as quickly as possible to process your refunds in the manner in which you paid. If you have questions, please contact firstname.lastname@example.org.
We appreciate your patience at this time. We know that early spring is the most natural time to come out to the Arboretum for a walk in the gardens to enjoy the fresh air, but maintaining public health must be our priority. We look forward to seeing you in the gardens just as soon as we are reassured that it is safe for all of our visitors to return. We will keep you updated on any developments, but in the meantime, if you have any questions about your membership, please contact email@example.com.
Any individuals that have planned events will receive outreach directly from a staff member to discuss your options.
We will continue to update the community as soon as information is available and is consistent with the evolution of this dynamic situation. Questions may be directed to firstname.lastname@example.org.
We appreciate your understanding during these challenging times and we thank you for your support. Please stay connected with us through Facebook, Instagram, and our website.
Unfortunately, Out on a Limb will be closed on Wednesday, January 29th through Friday, January 31, 2020 due to scheduled maintenance.
The Garden Railway will not be operational from 2:00 PM Friday (July 19) through the weekend (July 20-21). The trains will open for normal operation on Monday, July 22nd. Our Train Master reported that the trains will not operate in the excessive heat, citing electrical, track and rolling stock failures.
The Arboretum is open as usual. Click here for hours.
Garden Railway trains are not running Saturday, September 8th and Sunday, September 9th due to inclement weather.
Please note: The Rose Garden is closed for maintenance every Thursday morning until noon.
Weather conditions may limit garden access to certain features even if the garden is open – please check the web site or call (215) 247-5777 for updates before visiting. Our visitors’ safety in the garden is our top priority. Therefore when inclement weather is predicted, we will make decisions about closing the garden accordingly.
