Teacher Directory: Sally Petru


Sally began the study of botanical illustration after a 10-year career in landscape architecture and 12 years into raising a family. With experience in watercolor, and a strong background in horticulture, this art form came comfortably to Sally. She studied in small group classes with local teachers as well as with master teachers from Australia, Scotland, Canada and England. In 2010 she graduated from the Botanical Art Certificate Program at Filoli in Woodside. Sally has begun to work in pastels in a larger format.

Her artwork has been exhibited in several juried group shows.  These include Filoli’s Annual Botanical Art Exhibit, Exotica: Plant Portraits from Around the World in the Hearst Gallery at St. Mary’s College, The Art of Saving Oaks in Sausalito, and The Beauty of Botanicals with the ASBA in St Louis.  In addition, Sally assists in  the coordination of exhibitions for the Northern California Chapter, participating in all member exhibits. In 2013, she was accepted into the Filoli Florilegium.

She is the founding President of the Northern California Society of Botanical Artists, continuing to participate on the board. In 2014 she became a Director on the board of the American Society of Botanical Artists, slated as incoming President in 2018. In addition to commissions, Sally sells limited edition giclées and note cards stores around the Bay Area.

In 2011 Sally began to teach. She has been a guest lecturer at Merritt College, runs private classes and workshops in her home studio, and currently teaches at Strybing Arboretum in San Francisco.
