The Letitia Glenn Biddle Award, established in 2022, honors individuals dedicated to land stewardship, the art and craft of horticulture and design, horticulture education, and fostering opportunities for professionals working in the field.
Letitia Glenn Biddle moved to Andalusia in 1888 after marrying Charles Biddle. She noticed only vegetables were planted on the grounds, so she worked with gardeners to add flowers. Letita became a cofounder of the Garden Club of Philadelphia, which held its first meeting at Andalusia in 1904, and the Garden Club of American, which drafted its bylaws in the Billiard Room in 1913. The following decade she helped to expand the opportunities women had to the study and practice of horticulture as a cofounder of the School of Horticulture for Women, now Temple Ambler School of Horticulture and Landscape Design. Until her death in 1950, Letitia Glenn Biddle remained an avid horticulturalist and steward of the gardens at Andalusia.
