Pennsylvania Horticultural Society Library

The McLean Library and Archives was founded in 1828, one year after the Pennsylvania Horticultural Society was formed. It is a small research library consisting of collections on horticulture, gardening, urban greening and related information. Its archives document PHS’s nearly 200-year history including its major activities, the Philadelphia Flower Show and its nearly 50-year history in urban community gardening and greening projects. This collection consists of some of its earliest minute books and library records.
