The Pennsylvania Horticultural Society (PHS) is bringing two versions of its popular greening projects (called “horticultural interventions” by staffers) to underused lots in 2017. The South Street Pop Up returns with a new design that romances the garden, while the first-time uCity Square location transforms a vacant lot into an urban orchard of sustainable practices and repurposed materials. Both feature curated food and beer menus, with proceeds supporting PHS programs that address challenges such as healthy eating, food accessibility, environmental sustainability and urban livability. Open through October 2017. 15th & South Streets & 36th & Filbert Streets, (215) 988-8800, phsonline.org
