Hi, Dr. Hill,
This Liatris grew from seed collected from a plant growing along a rural road in the Fall Line region, full sun in sand-clay but primarily sand. Is has distinctively-sparsely-spaced flowers that are pale pink. The buds number from 6-9, but most commonly 9. The stems are lightly fuzzy. The photos were taken Sept. 6 – 7.
this individual is depauperate, the heads are usually more densely arranged when it grows in full sun. A possibility is Liatris earlei, but I really cannot be certain from this photo.
