bush morning-glory, Ipomoea leptophylla
On this Thanksgiving, I tried to think of a plant the Indians ate, and bush morning-glory came to mind. Indians might think that odd! They know how tough and bitter these roots are. And I am thankfull and not starving. These giant tubers were food for earlier people, but only in difficult times. They can be three feet long and forty pounds. They taste a little like sweet potato if you disregard the bitterness and tough texture. Better to leave these bush-like plants to flower and brighten things up. Bush morning-glories are a plant of the plains, growing in CO, KS, MT, NE, NM, OK, SD, TX, and WY. Logan CO CO, 6/25/13. Morning-glory family, Convolvulaceae.
