10. Wild Radish
Wild radish is sometimes confused with mustard, and it is capable of taking over an entire field. Although it is typically regarded as an invasive species, there is much to like about this plant. Every part of wild radish is edible, with the leaves having the peppery taste that is associated with non-wild radishes. The root can be eaten, but it needs to be peeled first. The fruit pods of this plant need to be harvested when they are young, and they taste exactly like radishes.
