The Geranium Files: Ken-Watt Court and the Neighborhood Garden Association traces the history of an early urban greening project undertaken by the NGA, the Ken-Watt Court Community Club, and the United Neighbors Association.

The Court, located at Kenilworth and Watts Streets, was demolished along with other South Philadelphia blocks to make way for the high-rise housing project Hawthorne Square (later renamed Martin Luther King Plaza). The housing project was imploded in 1999.
