Los Angeles area gardens with native plants. Theodore Payne Native Plant Garden Tour - +1 818 768-1802, organized by the Theodore Payne Foundation for Wild Flowers and Native Plants . The annual garden tour, which began in 2004, showcases mostly private gardens throughout the Los Angeles basin that feature 50% or more native plants.

The tour usually takes place in April over a weekend, with half the gardens open to attendees on Saturday and the other half on Sunday. In 2006, more than 1,700 people visited more than 30 gardens; in 2008, more than 1,000 people visited 38 private gardens; in 2009, more than 46 gardens are featured.
