Herbs and spices works

I am an assistant in a 3-6 class, I am looking for suggestions for our herb grinding and grating work. We currently have nutmeg and cinnamon for grating, and lavender, cloves, cardamom, mints for grinding. I like to match the herb/spice to the season but feel like I am using the same herbs over and over again. What herbs/ spices do you use for those works?
