Man. You work hard on a show to pack it with all sorts of useful information and what do people want to know? What's the name of that plant Joan Wood gave you. It's a Janet Craig, a member of the dracaena family, and apparently it's the ultimate geek plant. (It must be. The OS X spell check recognizes the word dracaena.) Why the ultimate geek plant? It requires little light, water, or care and cleans the air of pollutants including formaldehyde. Joan has vowed to bring another each time she comes on. Which is great since we plan to have her on a lot.
Think Geek ought to start selling these.
