From downtown San Francisco to the Golden Gate Bridge, walk by the roadside and pass many small attractions, and this is one of them. This is a greenhouse and botanical garden for rare plants. Completed in 1978, it is the oldest building in Golden Gate Park and one of the earliest urban greenhouses built in the United States. It is beautifully built in a white building in a large green lawn. The flower house is free to visit and is divided into five sections. Includes: lowland tropical area, highland tropical area, aquatic plant area, potted plant area. It is recommended to pass by, be sure to go in and see, generally half an hour is enough. If you just look at it, you can complete the visit in ten minutes. It is a long time to see a lot of rare plants that will appear in books and TVs here.
