Mother Earth's Plantasia is an electronic album by Mort Garson released in 1976.

The music on it was composed specifically for plants to listen to. Garson was inspired by his wife, who grew many plants in their home. Garson used a Moog synthesizer to compose the album, the first album on the West Coast composed entirely on the Moog synthesizer.

The album had a very limited distribution upon release, only being available to people who bought a houseplant from a store called Mother Earth on Melrose Avenue in Los Angeles or those who purchased a Simmons mattress from a Sears outlet, both of which came with the record. As a result, the album failed to attain widespread popularity around the time of its release. However, it has since gained a cult following as an early work of electronic music.
