I found an interesting article today of a woman who casts asparagus to divine the future, much like casting bones. She takes a handful of fresh asparagus and casts them on a flat surface, than interprets how they land.
Original article: Fortune-teller Jemima Packington uses asparagus to make predictions
I suspect this woman may be using asparagus for a bit of a publicity stunt (she has her own twitter account, @asparamancer), but I think it is an interesting look at how you can make your own divination systems, and how easy and simple they can really be. I'm not sure if asparagus has any occult connection to fortune telling, but this has made me think about how a green witch with a strong relationship with her plants could use them to divine. Although the original article was poking fun at her (and I wonder at her legitimacy as a seer), I think over this coming year I will try divining with my garden. It may provide valuable insight in to the nature and spirit of the plants involved.
I also think, especially for us newbies, it is a good reminder that you don't need specially carved runes or a nice printed tarot deck or $75 crystal ball to divine. Anything that you can pick up and work with can be used in the craft, even if it is destined to later become dinner.
