Must see · Garden · Nature / Park
The South Coast Botanic Garden is a 35 hectare (87 acre) garden in the Palos Verdes Hills, in Palos Verdes, California, United States, about 16 km (10 miles) south of Los Angeles International Airport. It has over 150,000 landscaped plants and trees from approximately 140 families, 700 genera, and 2,000 different species, including flowering fruit trees, Coast Redwoods, Ginkgos and Pittosporum. It is particularly rich in plants from Australia and South Africa. Its gardens include the Water-wise Garden, Herb Garden, English Rose Garden, and Garden of the Senses. A small lake and stream bed attract various birds such as ducks, geese, coots, and herons. Over 300 species of birds have been recorded.

The present garden site was operated as an open pit mine from 1929 until 1956, producing over one million tons of crude diatomite. With declining production, the land was sold in 1957 to the County of Los Angeles for a sanitary landfill, which was in use until 1965. However, starting in 1961, an experiment in land reclamation began when County Board of Supervisors approved a motion establishing 87 acres (35 ha) as the site of the South Coast Botanic Garden, which was ultimately landscaped over 3.5 million tons of refuse, in a classic example of land recycling. The Sanitation District in cooperation with other County agencies carried out initial planning, grading and contouring. Operating responsibilities were given to the Los Angeles County Department of Arboreta and Botanic Gardens. In April 1961, the first large-scale planting took place on completed fill overlooking Rolling Hills Road, with over 40,000 plants donated by individuals, nurseries and the County Arboretum.

The site presents unusual difficulties in gardening. First, its soil is composed almost entirely of diatomaceous earth. Second, because of the diverse nature and thickness of the fill, settling rates vary throughout the garden resulting in frequent irrigation system breakage. Third, heat is caused by decomposition of organic matter below the soil surface, and it is accompanied by the production of gases, primarily carbon dioxide and methane.

  • The only reason for the 1 less rating was the river bed water area still under construction for years! That’s the only eye sore and the detours around it are misleading. Besides that place is amazing....  more »
  • This is my second time visiting the beautiful South Coast Botanic Gardens. The gardens are so impressive and so local to the region. I was able to learn so much about the variety of landscape...  more »
  • First time coming here! All I can say it's such a great spot for a nice walk surrounded by nature. It has a beautiful garden, flowers, trees, and a few animals. Definitely bring a couple of water bottles if you plan on hiking a good while, sunscreen for those sunny days, I'd recommend proper shoes depending where you hike, there are areas you may slip. Hope to go back soon! Enjoy the nature! ❤
  • This is a wonderful botanical garden experience within easy driving distance from most of the greater Los Angeles area. There are extensive trails to stroll along discovering fantastic plant collections. It setup for adult enjoyment and they have interactive kid programs too. Plan to spend a minimum of two hours, but a half a day would disappear if you tired to see everything. Come visit this beautiful setting and enjoy exploring the grounds with family and friends.
