Plant Collection

More than 11,000 accessioned plants of over 2,500 taxa are growing in the Morris’s living collection. These include representatives of the temperate floras of North America, Asia, and Europe. This historic collection traces its foundation to John Morris’s interest in plants from around the world and includes plants collected in China by E.H. Wilson at the turn of the century. Many of the Delaware Valley’s "trees-of-record" (the largest of their kind) are found in the Morris. Most notable are the katsura and the trident maple.

Staff members have regularly engaged in plant collecting expeditions in Asia and the United States, increasing the diversity of plants available for today’s urban and community landscapes. Currently, plants from 30 countries are represented in the collection with a primary focus on Asian temperate species. Significant plant groups in the Morris’s collection include maples, magnolia species, native azaleas, members of the witchhazel family, roses, hollies, and conifers. 

Help Protect Our Trees 

Please note, visitors are not allowed to climb or sit on the limbs of trees. The Morris is home to a number of champion trees, some of which are very old. With 150,000 visitors annually, climbing becomes a safety issue for both children and the trees. We don’t want any visitors or trees to break a limb. Thank you! 

Seasonal Plants
