About Dalea gattingeri (A.Heller) Barneby
Dalea gattingeri, commonly known as purpletassels or Gattinger prairie clover, is a flowering plant species belonging to the legume family. It is native to the Southeastern United States, and its range there is restricted to limestone cedar glades located in Tennessee, Alabama, Georgia, Missouri, and Arkansas. Its populations are widely scattered and each is small in geographic size, with the majority of populations occurring in the Nashville Basin. This perennial plant produces purple flowers during the summer. It has been found to contain allelopathic chemicals that inhibit the growth of a nearby species, Minuartia patula.
