Philadelphia Botanical Club

Field Trips and Workshops

Philadelphia Botanical Club field trips offer a way to become familiar with our region's plants and habitats, along with good places to see them. The trips are run by volunteers who know the site, and everyone on the trip can participate in spotting and identifying the plants.

Unless noted otherwise, trips start at 10 AM. Unless noted otherwise, trips are free and open to the public.

Please feel free to provide feedback or comments that may enhance our offerings to our field trip coordinator, David Lauer,

Field trip leaders can download instructions for trip reports.


Note the new date: February 24 (Saturday) at 10 AM: Pennypack Preserve, Montgomery County, PA
Postponed from February 17 because of the weather. This is a joint trip with the Delaware Valley Fern and Wildflower Society. The Pennypack Preserve, almost 900 acres, is owned by the Pennypack Ecological Restoration Trust. It has a range of habitats, making it a good site for wintertime botany. We will explore woods, restored grasslands, marsh, and pondside. Some of the woods is old growth, with oaks that date back as far as the 1760s. The grasslands offer sweeping views over Huntingdon Valley. The preserve has been designated as an Important Bird Area, so birding enthusiasts may want to bring binoculars. We will walk approximately 2.5 miles, including some moderate hills. Expect dry walking, though we may encounter some mud if it rains shortly before the trip. If there is deep snow or steady rain, the trip will be postponed. To learn about any postponement, register with the leader ( or check this page after 7:30 AM on the day of the trip.
Registration: Registration is encouraged. Register by emailing the trip leader ()
Directions: Park in the main preserve parking lot at 2955 Edge Hill Road, Huntingdon Valley, PA. If you are using Google to navigate, enter the street address or "Pennypack Ecological Restoration Trust Parking" or you may be sent to the wrong entrance.

June 2-6, 2023 (Sunday to Thursday): Joint Field Meeting (BotSoc)
Bruce Peninsula, Ontario, Canada

Each year the Botanical Society of America NE section, the Torrey Botanical Society, and the Philadelphia Botanical Club sponsor a field meeting in eastern North America. The 2024 meeting will finally return (after delays due to Covid) to the Bruce Peninsula, Ontario and will be housed at the Evergreen Resort.
Field Trips: We will visit a number of fascinating areas and habitats, including alvars, sandy shorelines, marl fens, upland forest, forested dunes, marshland, and rocky forest. Just a few of the species highlights we expect to see are ram's head lady slipper, sticky tofieldia, dwarf lake iris, lakeside daisy, butterwort, Hooker's orchid, rare ferns, seaside arrowgrass, buckbean, paintbrush, tamarack, and bladderworts. Field trips are being organized and led by Walter Muma and Tyler Miller. Both are experienced field botanists with a focus on the Bruce Peninsula.
Evening Speakers: Evening presentations will include orchids of Grey-Bruce, parasitic and carnivorous plants of the Bruce, and more. These will be presented by Walter Muma, Tyler Miller, and others. Tuesday evening will feature "Orchid Quest," by Willy and Audrey Waterton, about their two-year quest to find and photograph all of the orchid species of Bruce and Grey Counties. The resultant book, Orchids of Grey-Bruce, will be available for purchase at this entertaining and informative presentation.
Lodging: Housing will be at Evergreen Resort. Cabins include all bedding linens and towels, and daily housekeeping. Evergreen is a rustic resort with the atmosphere of the 1930's. It is one of the long-standing "family" lodges located along the Lake Huron shoreline at the base of the Bruce Peninsula. The owners, the Bennett family, have always worked to maintain a natural setting as possible and to focus on the surrounding natural history.
Meals: Breakfasts and dinners will be served at Evergreen Resort. Lunch is box-style and will be picked up at breakfast each day.
Registration and additional information: Download in PDF or Word format. The registration deadline is April 12.

dwarf pitch pines (Pinus rigida)
