The Scott Arboretum holds three Nationally Accredited Plant collections including Ilex (hollies), Quercus (oaks), and Magnolia. Our first collection to get Plant Collections Network status was the holly collection. The lion’s share of this collection is found in the James R. Frorer Holly Collection on the south facing slopes along the Crum Creek. This collection was donated by Swarthmore College graduate, James R. Frorer in 1974 from his property in Wilmington, Delaware. Today, the collection represents over 300 different kinds of hollies.
