San Francisco's Conservatory of Flowers has been in Golden Gate Park since 1879, surviving the 1906 earthquake and thriving to this day. They specialize in high altitude orchids, with about 700 of the 1000 species. They are kept in a humid but somewhat cool room, and many were in bloom when we visited. I knew Jasper would be excited to see their collection of carnivorous plants, mostly tropical pitcher plants, which have really captured his imagination. We were not disappointed. Both the plants and the architecture are stunning.
