Capital Campaign & Construction

At the Delaware Center for Horticulture, we believe that success in environmental justice is essential for communities to thrive. That is why we work hard to partner with organizations and people like you to make a positive impact through four program areas: Urban Agriculture, Trees, Public Landscapes, and Education.


TheDCH headquarters, situated on 1.3 acres adjoining state parkland in Wilmington’s Trolley Square neighborhood, is a collection of historic structures that was innovatively merged into a single building in 1991.  It has been an ideal base for operations for more than two decades, but to continue increasing our reach and effectiveness statewide, it was time to expand and update. In June 2014, TheDCH leadership voted to move forward with Phase I of a $3.5 million green renovation and expansion plan. Now, construction is under way, and it’s exciting to see the shared vision come to fruition.
