History of Moonlight & Roses

As a longstanding Arboretum tradition, the Moonlight & Roses gala, which always takes place in early June, is unsurpassed.

The lively garden party we now know as Moonlight & Roses has had a colorful evolution. In the early 1970s, it was dubbed the Spring Fling, and was held on the lawn behind Gates Hall. The late Jane O’Neill was instrumental in the success of the gala in those early days.

In the 1980s, patrons and contributors donned their garden party attire for the event that was rechristened Moonlight & Roses . The evening traditionally begins with cocktails served in the Rose Garden, while dinner, served by a professional catering staff, is held in a festive tent atop the hill near the Widener Visitor Center. Music and dancing round out the evening of friendly conversation and gourmet dining.

Moonlight & Roses has always provided an intimate setting unique to Philadelphia charity events, and is enjoyed by a capacity crowd each year. The Morris Arboretum's annual fundraising gala, Moonlight & Roses , has become a tradition among friends, families, and colleagues in the Delaware Valley.
