Next was a small garden showing how the Native Americans grew the “Three Sisters” (corn, beans, and squash.) Corn was grown in hills and it took nitrogen out of the soil. Beans added nitrogen back into the soil and the bean runners climbed up the corn stalks. Squash was grown around the edge of the garden. Its prickly stems ran along the ground and discouraged small animals from coming in and eating the vegetables. I was intrigued by the colorful “scarecrow” figure.
