Plants with Pitfalls
Until November 4th, 2007 the San Francisco Conservatory of Flowers is hosting a special carnivorous plant exhibit. It is worth checking out if you are already visiting [or live in] San Francisco.
I now regret being so focused on taking pictures rather than reading the signage and writing down the names of the plants. I believe this carnivorous plant is of the pitcher plant variety. Specifically I have estimated it is some type of North American Pitcher Plant belonging to the genus Sarracenia. If you are a plant person, feel free to correct me.
