Sutro Project / Conservatory of Flowers
Restored in 2003, the building is the oldest surviving flower conservatory in the western hemisphere (1878) and consists of 25 tons of glass.
Living inside are more than 2000 plants - some over 100 years old - divided into 5 sections: Aquatic Plants, Highland Tropics, Lowland Tropics, Potted Plants and special exhibits. Effectively a large "green house", the conservatory is temperature controlled and can make for a good wet/cold weather day activity.
Watch your fingers in the carnivorous plants section :)
Address: Conservatory of Flowers, Golden Gate Park, SF
