Who We Are

The Hansberry Garden and Nature Center (HGNC) is a community garden and resource for environmental education in the heart of Philadelphia’s Southwest Germantown, located on the corner of Wayne Avenue and Hansberry Street at 5150 Wayne Avenue.

We are a 501(c)(3) non-profit organization invested in our community through organic gardening, the City Harvest Program of the Pennsylvania Horticultural Society, and educational programs for children and adults. Members are residents of Southwest Germantown.

 History, Mission, and Leadership

Our History

The history of HGNC began in 1981 with a demonstration garden at 5150 Wayne Avenue funded by a federal grant from the Neighbors Community Program.

In the 1990s the City of Philadelphia razed the house at 5148 Wayne Avenue, making the garden at 5150 impossible to use. Former garden members and neighbors joined in 2001 to develop a vision of a community garden and nature center that would serve the Germantown community. In 2002, the Hansberry Garden & Nature Center Steering Committee was formed and began clearing the land, organizing, and fundraising.

Later that year, Philadelphia Green put up a fence, and raised beds were built with funds from Community Gardens Project. The Hansberry Garden & Nature Center, Inc., became designated a 501(c)(3) organization under federal law in July of 2004. In 2008, 5148 Wayne Avenue was purchased by HGNC, and the city recently turned over the deed to 5148.

Our Mission

The Hansberry Garden and Nature Center will be an educational community resource center for environmental education in the Wayne/Hansberry region of Germantown. The mission of the nature center is to:

  • Promote awareness and appreciation of the natural world;
  • Promote understanding of the natural cycles and behavior of plants and animals;
  • Engender the values and attitudes among people that foster responsible stewardship of our urban environment.


  • Construction of a facility at the corner of Wayne and Hansberry that will include an office, classrooms, meeting or work space, and a greenhouse;
  • Development of themed “teaching gardens;”
  • Presentation of quality programs in environmental education for children and adults (after-school, weekend workshops and/or summer day camp programs);
  • Development of programs that will include environmental and community development-related work skills;
  • Promote community recycling and litter control;
  • Community organization/mobilization around environmental issues that affect our neighborhood;
  • Science enrichment programs for school classes;
  • Protection of wild/natural areas (these are not “waste areas).
