Aster umbellatus (Flat-Top White Aster)

One of the first asters to bloom in the summer. Fairly flat clusters of small, white flower heads can reach widths of six to 10 inches. Plants have elliptical to lance-shaped leaves, three to six inches in length, spaced alternately along the main stem.

Additional Information:
This perennial native plant is an important host plant in the life cycles of Pearl Crescent and Silvery Checkerspot butterflies.

Several Native American tribes used the smoke from burning aster plants to assist in reviving persons who had fainted. Some other tribes brewed a tea from aster plants to relieve headaches.
