Mustard and Cress (Brassica hirta and Lepidium sativum)
Try these spicy, peppery sprouts if you are looking for a flavor with a bit of zing. You could sow them on the top of moist cotton stuffed inside an empty eggshell. Draw a face onto the shell. As the seeds grow, they'll look like a wacky hair style. Harvest in 7 days.
