With 2,143 plant species, San Diego County has more species of plants than any county in the contiguous United States. The geography of the county ranging from salt marshes, lagoons, coastal sage scrub, grasslands, chaparral, oak woodlands, stream sides, mixed conifer forests, freshwater marshes and meadows, to desert makes gardening here fascinating and complex. The San Diego Horticultural Society is dedicated to educating residents about gardening in this rich horticulture environment with many micro-climates.

The San Diego Horticultural Society sprang from modest seeds sown in 1994 by our founders Don and Dorothy Walker, Steve Brigham, Diana Goforth, Laurie Bussis, Bill and Linda Teague, Adele Snyder and Kathy Musial. Their vision was to establish a friendly group of garden enthusiasts from beginners to skilled professionals to get together and share information and the joy of gardening. Our first meeting was held at San Diego Botanic Garden - then named Quail Botanical Gardens.
We grew so quickly that in just two months we had to find a larger meeting space. SDHS now has over 1100 members, and our monthly meetings are held the second Monday of the month in the UTC area at Congregation Beth Israel.

Susi Torre-Bueno served as president from 2003 to 2010 and was instrumental in growing the organization and establishing us as a San Diego institution.  In 2012 she was honored our Horticulturist of the Year.
