I need some wheat!

I'm working on the final panel for the St. Mark's Triptych.  Here you see I've set up a still life based on the Lord's Supper and Baptism.  Does anyone have a handful of wheat that I can use for this?  I had some for the St. Croix project, but it got too damaged to use.  Any farmers in the area that can spare some wheat for a good cause?
