The San Francisco Conservatory of Flowers, is in Golden Gate Park. The text from the Conservatory website (www.conservatoryofflowers.org) describes it as follows:
From Borneo to Bolivia, the seventeen hundred species of plants at the conservatory represent unusual and often endangered flora from the tropical forests of more than fifty countries around the world. Like a belt that wraps around the earth's midsection, the tropics lie along the equator between the Tropic of Cancer and the Tropic of Capricorn. They include many countries in Central and South America, Africa, and Southeast Asia. There is good reason for this enduring orchid fever. The variety and range of these plants is unmatched. Orchids are one of the largest and most diverse family of flowering plants with an estimated 25,000-35,000 species and more than 110,000 human-produced hybrids. Orchids account for 10% of all flowering plant species. Orchids have adapted to almost every environment on earth and can be found from the dry scrub of Western Australia to the snow-covered Swiss Alps. Even Death Valley with two inches of annual rainfall is home to orchids. In the state of California you can find 32 different species
