Burdock
With thistle like flower heads, the medium to large sized burdock thrives in temperate regions of the United States. You can eat the leaves and peel the stalks for consuming the plant raw or boiled. The leaves tend to leave a bitter aftertaste, which prompts some hikers to sprinkle the chopped leaves on other types of foraged foods. Boiling the plant two times removes most of the bitter aftertaste.
