The young actress Alicia Silverstone is an ardent environmentalist and her sustainable garden in the Hollywood Hills features that in many ways. Here are the main elements of sustainability on her steep hillside garden:

       Plantings are primarily of California natives and plants from other Mediterranean climates .

       Steep hillsides use drip irrigation and MPR rotors for maximum irrigation efficiency.

       Heavy mulches of "Gorilla Hair" to keep mulch on slope and minimize water loss.

       Weathermatic Smart Line Controller technology with weather station.

       Grey Water system to water fruit trees, and other edible shrubs and vines.

       Rain catchment system to collect rain water off house roof and deck  and put it on slopes.

       Edible gardens include Avocado, Figs, Citrus, Passion Fruit, Berries, Vegetables & Herbs.

       LED lighting for outdoor lights.

       Use of recycled broken concrete for patios and planter boxes.
