Clasping-leaf Coneflower, Dracopis amplexicaulis is Native to Texas and other States.

Neutral Terry On Mar 14, 2001, Terry from Murfreesboro, TN (Zone 7a) wrote:

Native from Kansas to Texas and Georgia, an annual grown primarily for landscaping or naturalizing in meadows and on roadsides Has elongated, bluish, glaucous leaves that "clasp" around the stem at the base. The flower heads are similar to those of black-eyed susans, but they are smaller (mostly 1-2 inches in diameter).

The yellow outer "petals" droop as the flowers mature, and the cylindrical black center (receptacle) is elongated up to 2 inches in length. Flowering begins in June.

It is adapted to many soil types, but it generally prefers a moist site. Natural stands are usually found on bottomland areas with a fairly rich soil and ample moisture. It prefers full sun and will not persist in a shaded location.
