Spread of Three Sisters
Depicts a Native American woman spreading seeds in a field. She is planting seeds for growing corn, beans and squash on the same mound, which is an ancient Native American agricultural method of planting known as "Three Sisters". The squash plant provides ground cover to keep weeds away, the bean vines help add nitrogen into the soil and the tall corn stalks provide support for bean vines to grow. This amazingly efficient planting method increases food production by 30% or more!
