Many of our favorite flowers are native to North, South, and Central America. Some were domesticated by American Indians long before the Europeans arrived. The tuberose, for example, has been grown in Mexico for so long that its origins are lost. Some, like the amsonia swamp sunflower, have only recently begun to be appreciated. Following are some flowers for a garden of the Americas:

• Tuberose Polianthes tuberosa - Like corn, the tuberose was domesticated by pre-Columbian Indians of Mexico, its origin lost in antiquity. It is one of the most fragrant flowers you can grow and a wonderful cut flower.

Yuccas were used by American Indians for food, fiber, and soap. Fibers came from the leaves, and the tuberous root was used to clean fabrics and in purification rites.
