The garden site was originally a surface mine for diatomaceous earth before being converted into a sanitary landfill in the 1950s.
Following the landfill's closure, the garden was established as a multi-year landscape reclamation project starting in 1961.
The garden maintains a specialized collection of over 200 varieties of roses.
The Mediterranean climate of the Palos Verdes Peninsula allows for the cultivation of plants from all five of the world's Mediterranean climate zones.
An extensive Banyan tree collection exists on-site, which is rare for Southern California due to local temperature constraints.
The garden serves as a site for ongoing environmental studies regarding soil and gas management on reclaimed landfill properties.
South Coast Botanic Garden is a 87-acre horticultural site located on the Palos Verdes Peninsula, built upon a former open-pit diatomaceous earth mine and county landfill. The garden features over 2,500 species of plants from diverse climates, including Australia, the Mediterranean, and South Africa. A central feature is the Banyan Grove, characterized by its complex aerial root systems. The grounds include a formal rose garden, a Japanese garden, and a cactus and succulent collection. The site serves as a bird-watching destination, having recorded over 300 avian species throughout its history. Dedicated educational programming and seasonal light displays are held on the property regularly. The topography is largely flat, providing accessible paths for visitors to navigate the various micro-climates represented. It is managed by the South Coast Botanic Garden Foundation, a non-profit organization.
