Description:

Pickerings dawnflower is a spreading, herbaceous, perennial vine that forms large mats and clumps primarily in the sandhills and sandy woods of the Southeast. It is usually found in the driest, most barren, deep-sand areas and occasionally colonizing roadsides and other disturbed areas (TNC 1993). It produces small white and sometimes pink morning glory like flowers from June through September. This taxon is easy to recognize by its growth form, with numerous stems arching from a central point, then trailing radically away, forming a mound 1-2 m in diameter. There are 43 known populations, many of which are vulnerable to habitat destruction.

North Carolina Botanical Garden has had some success with seed germination, but it has been sporadic and seedlings have been extremely slow growing. Stylisma pickeringii var. pattersonii is a rare species in Illinois. Extensive research has been performed on this species by individuals from Eastern Illinois University and the University of Illinois at Urbana-Champaign. (Donnelly et al. 2001; Heisler et al. 2000, 1999; Kerber 2000; Sojka et al. 1999; Todd et al. 2000, 2001a, 2001b, 2002)

Many populations occur in managed sandhills that presently receive regular prescribed burns. However, there are a significant number of roadside and other populations that lack a current management strategy (Bert Pittman, SC Natural Heritage Trust Program, pers. comm.). Researchers in NJ report that prescribed burns destroyed populations in their state (TNC 1993).
