In 1975, the Greater Wilmington Development Council approached GCW to spearhead interest and funding for a plaza park in front of the Brandywine Building on Delaware Avenue. The Community Projects Committee, with Mrs. Eleuthere I. du Pont (Minda) as chairman, approached downtown businesses and private foundations and was successful in raising most of the funds necessary. Later the plaza was renamed H.B. du Pont Park Plaza
The Wilmington Garden Center and The Delaware Center for Horticulture (the DCH)
In 1977 the Community Projects Committee, under the leadership of Mrs. Henry Belin du Pont (Emily), decided it was time to create a garden center in the city, a headquarters for the exchange of horticultural information and ideas. It would sponsor lectures and workshops and organize plant sales and exhibits. The GCW raised $18,000; this was matched by the city, enabling the purchase and renovation of a small row house at 503 Market Street. The Wilmington Garden Center was dedicated in 1977. With an emphasis on neighborhood outreach and horticultural education, the center flourished, offering classes to the community on gardening, urban beautification, and tree tending.
Fifteen years later, a $2.2 million fund drive allowed the center to move to 1810 N. DuPont Street. The mission of the Wilmington Garden Center continued, with over 400 volunteers and 600 members, and acquired a new name, the Delaware Center for Horticulture. Since inception, members of GCW have passionately supported the organization and served as dedicated volunteers and Board Members. All GCW presidents serve on the DCH Board of Directors. Celebrating its 40th anniversary in 2018, the DCH remains committed to promoting a knowledge and appreciation of gardening and conservation, by working to create community gardens, supporting urban farms, beautifying public spaces and roadways, and educating the communities of Delaware.
