Botany in movies and on TV is usually absolute and utter crap, and it ruins it for me. Plants frequently are a give away that the filming was done in a location distant from where the action was supposed to take place. Even pure escapist garbage gets really annoying like a recently viewed "Librarian" episode where the hero finds quaking aspen is a Louisiana bayou and it's supposed to be part of some Christian legend which of course would have been set in the Eastern Mediterranean. CSI is ever rediculous in their pin-point plant identifications from a single trichome recovered at a crime scene. Except I did see one of my mentors ID a plant from just a trichome once. So imagine my surprise to learn that even when it doesn't matter, i.e., purely science fiction, the makers of Avatar consulted a botanist! Wow! It happens so seldom, but of course we are are the only ones who know because no one else notices. At least this gives me a reason to see the film.
As an added bonus, my colleague recommends some "other-wordly" plants you can grow in your garden. Enjoy!
