2022 Honoree

Sally Gendler (1960-2020)

This year we are privileged to honor the memory of Sally Gendler at the 2022 Moonlight & Roses gala. Originally from Hamden, Connecticut, Sally moved to Philadelphia following her marriage to Steven Gendler. After raising their two daughters, Abigail and Liza, Sally and Steve moved to nearby Meadowbrook Avenue which enabled Sally to walk directly into the Arboretum. Sally took full advantage of her proximity to the gardens and served as an active education guide, horticulture volunteer, and archive volunteer.

She brought her high-spirited enthusiasm, considerable expertise and love of all things related to gardening, growing and environmental protection to everything she did. She reveled in sharing her love of plant life with children as well as adults. Sally was a member of the Arboretum’s Directors Guild and the Moonlight & Roses planning committee, serving as the chair in 2019. She was an active Penn State Extension Master Gardener, and volunteered at The Mt. Airy Playground, where she created an innovative garden to table program through which she taught planting, sowing, and cooking to children and parents in the local community. Sally was a life-long champion of the Morris Arboretum, and we are deeply honored to have this opportunity to pay special tribute to her memory at this year’s gala.

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.
