Apiary Studio, a landscape architecture and design firm based in Germantown, and Robertson’s Flowers & Events in Chestnut Hill, were among the award winners at the Philadelphia Flower Show, which closed Sunday after a weeklong exhibit at the Pennsylvania Convention Center.

Apiary, which specializes in using uncommon, unconventional plant species, won a gold medal for its “Right of Way” exhibit. The display celebrated highway roadsides as a unifying American experience with a green throughway. The firm, which also won awards at last year’s show, also was recognized for its “intent to take a strong stance on a humanitarian or environmental issue.”

Robertson’s, returning to the show for the first time since the pandemic, received a silver medal and special achievement awards for creativity and use of color. The florist’s exhibit, “Harmony in Geometry,” combined a medley of circles, squares, triangles and other shapes with vividly colored flowers in a reflection of the Flower Show’s theme “United by Flowers.”

Temple University’s Department of Landscape Architecture and Horticulture in Ambler won a gold medal, and several awards in the education category including honors for demonstrating gardening and horticulture as a force for the “greater good.” The school used flowers to explore Philadelphia’s maritime history. Representing East Falls, W.B. Saul High School of Agricultural Sciences was awarded a bronze medal for a display that focused on the school’s 130-acre farm campus and its Roxborough neighborhood.
