PBS is airing the Botany of Desire Documentary tonight, Wednesday, October 28 at 8/7 central. I may have to go over to my mom's house so I can watch it. We don't own a TV. This documentary is based on Michael Pollan's best selling book of the same name. I read this book a long time back and love it. It's a look at four plants: apples, tulips, potatoes and marijuana. Couple the magnificently written book with beautiful photography and this should be one spectacular show! Check out the preview below.
