There is a wonderful book called "Buffalo Bird Woman's Garden"
This book is a story told by Waheenee, a Hidatsa Woman born in 1839, about exactly how they planted their all important gardens.
The 3 sisters in their gardens, Squash, Corn, and Beans also had another important sister, Sunflowers. Generally their Beans were in separate hills, and the squash was nearby. Her Sunflowers were planted at the perimeters because they looked better there.
Yes, other tribes did things differently, but theirs were generally very successful. They lived in North Dakota.
The main intention of gardening for Indians was for food, especially for food during the winter. That means most of their corn was dry flour corn. They did have sweet corn, sometimes fresh, but even that, much was dried and reconstituted for when desired. Most of their beans were dry beans. Her particular family kept beans to more of a minimum because of the, ahem, result beans can make. 10 or 14 lived in a house.
It really is a great book. There is also an autobiography of her life that is a great book. They are both online and FREE to read online!
