This is a common native forb in meadows, fields, and woodland edges from southern Quebec & Ontario down into Florida to Texas. In my old book from 1968 of A Field Guide Tp Wildflowers by Peterson & McKenny on page 96 there are two asters listed next to each other of the Small White Aster of Aster vimineus and Calico or Starved Aster of Aster lateriflorus that were so extremely similar that botanists must have wisely decided they are really just one species. Most New World Asters were given a new name of Symphyotrichum and "vimineus" was dropped. This forb has small white ray flowers, looking like "petals" and disc flowers in the "nose" or "button" that begin yellow and turn reddish-purple. The flowers are crowded on the stems and often grow more on one side of the stems. The low leaves are larger of up to 6 inches long by 1.5 inches wide, but they decrease in size a lot as they ascend the stems. The stems are sort of purplish. The root system is both fibrous and of rhizomes. A few native plant nurseries sell some, including seed, but not a big, popular item.
