Sorry, I thought I was responding to Lee privately. I don't know of any geophyte DVDs, and my producer and I looked into it quite extensively. There are a few gardening and reference DVDs, but none that are more botanically oriented. I think most plant people prefer books, but there are some advantages to audiovisual methods, like being able to demonstrate things that are not so easily described in text, plus you can put as many pictures as you like and film footage. I am not doing this myself, it is way beyond me technically, and I don't want a DVD that looks like a home video!! Diana
