The Catalogue of Plants in the Living Collection

This online catalogue is a listing of every living plant for which collection records are kept. It represents 8,055 records for plants, cuttings, and seedlots alive in the Arboretum as of January 2021. Because a record may have more than one item, our collection has over 13,000 accessioned plants, cuttings, and seedlots. These 13,000 items represent approximately 2,600 taxa (types of plants). Annuals and most perennials are not accessioned.

This list is arranged alphabetically by scientific name. It gives accession number, current location, scientific name, common name, provenance, source, how received, collector number, and native range for each item. Accession numbers ending with an “#” are cuttings, seedlots, or non-labelled seedlings in propagation.

A grid map of the Arboretum is included to help users locate plants throughout the living collection. Plants located at the Greenhouse, the Nursery, or Bloomfield Farm can be viewed by appointment only.

Our system is having an issue recognizing memberships at this time. We are working as quickly as possible to resolve the issue.

All guests, including members, are required to reserve advance tickets for admission. Parking is included with your advance ticket.

Guests are not required to wear face coverings outdoors, but face coverings must always be worn indoors.

Our Train Master reported that the trains will not operate in the excessive heat, citing electrical, track and rolling stock failures.

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.
