Kendal at Longwood and Crosslands are sister continuing care communities located back-­to-­back in southern Chester County, near Longwood Gardens between Chadds Ford and Kennett Square, PA. More than 500 residents live independently in cottages and apartments with personal care and skilled nursing available on each campus. Activities are organized by resident committees which plan numerous programs including lectures, concerts, and trips, as well as the maintenance of several public gardens.

In February 2013, the Kendal Crosslands Arboretum (KCA) received recognition as an official arboretum by the Arbnet Arboretum Accreditation Program of the Morton Arboretum in Lisle, Illinois. The Kendal Crosslands Arboretum is believed to be one of the first continuing care communities to be so designated. In February, 2018, the KCA was accredited as a Level II Arboretum making it only the second Level II CCRC listed on the Arbnet Register.

Trails traversing mature woodland and a stream link the two sections of the 500 ­acre combined campus. Within the combined 300 landscaped acres, more than 400 trees are labeled with their common and scientific names. Seven loop walks feature more than 200 trees that are easily accessible from roads and hard ­surface pathways. Maps, tree lists and descriptions of the trees are available at the reception desks on each campus.
