Knowing Native Plants classes are held on Saturdays in the Preserve Auditorium.  The fee for members is $15 and for non-members is $20.  Pre-registration is suggested.

For registration information and class descriptions, check out our Calendar of Events.

2016 Knowing Native Plants Schedule: 

Amazing Asters - September 17, 1:00  - 4:00 p.m.

Fall is peak bloom time for members of the Aster family. Explore our woods and meadows with Naturalist Mary Anne Borge to discover asters, goldenrods, bonesets, coneflowers, tickseeds, and other yellow composites. We'll look for signs of the relationships these plants have with the insects, birds, and other animals that depend on them. Presentation/di​scussion followed by an outdoor tour.

Trees of the Preserve - October 15, 1:00 – 4:00 p.m.


Learn about many of our native tree species in the glory of their fall color! Do you know which native tree was originally used to flavor root beer? Or why leaves change color? The class will cover these topics and more, as well as provide tips on how to identify the trees of the Preserve, both deciduous and evergreen. Presentation/di​scussion followed by outdoor tour.

From Flowers to Seeds - November 7, 10:00 a.m.  – 1:00 p.m.

How do angiosperms reproduce sexually? Naturalist Ed Lignowski will answer this question by discussing the life cycle of flowering plants from pollination to fruit/seed dispersal. General anatomy of flowers will be covered, and specific examples of native plants will be used to illustrate the many interesting differences in floral structure and function that occur in nature. The events following pollination leading to the development of fruits and seeds will be explained. Learn about the various types of native plant fruits and examples of how they provide nutrition for wildlife. Presentation/di​scussion followed by an outdoor tour.

Ecology & Conservation

Botanical Master Class:  Fruits & Seeds

Wednesday, September 21, 9:30 a.m. – 12:00 p.m.

Members:  $25; Non-members: $30

Space is limited.  Advance registration required.

The focus of this class will be dispersal mechanisms plants have evolved to overcome their typical lack of mobility.  Over the eons plants have evolved relationships with other organisms as well as dependence on inanimate forces to colonize appropriate habitat.  We will also consider situations where plant species have outlived their original dispersal partners.

Dr. Ann Rhoads is a botanist recently retired from 36 years of employment at the Morris Arboretum of the University of Pennsylvania. She co-authored The Plants of Pennsylvania, An Illustrated Manual, with Dr. Timothy A. Block.
