Conservatory of Flowers in Golden Gate Park. The Conservatory is a greenhouse and botanical garden that contains a wide variety of rare and exotic plants; orchids and maidenhair ferns (my favorite) were in abundance!
I'm still in awe of the architecture of this place. I love how it's made entirely of wood and glass and painted all in white! Very beautiful and very photogenic.
