Time in the Garden

Time is the essence of gardening and the natural world. Whether counting tree rings, or planting seeds, the passage of time marks the life of the garden. Sunflowers bend to follow the path of the sun throughout the day. Leaves turn colors in autumn as day length shortens. Common names of flowers often express the essential essence of time’s import: daylily, nightshade, four o’clock. Runs through October 28th.

Frank DePietro

website | email

Frank DePietro prepared for his artistic career by majoring in painting and ceramics at Bloomsburg University. In addition to exhibiting his paintings both locally and nationally, Frank teaches classes and workshops at the Delaware Art Museum and Longwood Gardens. Inspiration for his paintings comes from close observations of the natural world. The subject is portrayed in a manner true to their existence in a specific time and place, and selected based on considerations of visual relationships to formal elements of painting.

Judith Harold-Steinhauser


Judith Harold-Steinhauser has a background in painting and did her graduate work in photography, studying with Aaron Siskind at Chicago’s Institute of Design. Her photographic work is known for experimentation with allusion and enigma being more important than photography’s traditional role of description. Judy’s work is in many national public and private collections, including The Philadelphia Museum of Art, The Philadelphia Public Library and the Woodmere Art Museum.

Maura Matthews is the owner of the Pigs Alley Gallery in Flourtown, PA which serves as her studio, gallery and classroom. After a career in the written word as a writer, editor and development professional, Maura now concentrates full-time on her art. Her medium is oil on canvas with a palette knife that allows her the looseness and texture of a “modern impressionistic” style. Maura’s work has hung in numerous solo and group shows throughout the Delaware Valley.

Deirdre Murphy


Deirdre Murphy, adjunct professor at the University of Pennsylvania, earned her MFA degree from the University of Pennsylvania and her BFA from the Kansas City Art Institute. Deirdre has been researching the effects of climate change on bird migration for several years, using the visual data that scientists share with her to conceptualize and execute her paintings. Her fascination with avian migratory patterns and the effects of global warming have led her research to Hawk Mountain Bird Sanctuary, Powdermill Nature Reserve and Drexel University’s Academy of Natural Science.

Jacquie O. Young


Jacquie O. Young studied art and photography at Kutztown University and the Antonelli Institute of Art & Technology. A diagnosis of multiple sclerosis changed the course of Jacquie’s life and work. Previously a portrait photographer working in film, Jacquie was inspired to take coursework in digital imaging to give her a path of therapy creating with graphics. Infrared photography has become her current passion and the medium through which she portrays the “beautiful chaos” of a cultured space being reclaimed by nature.
