Southern Dawnflower is a native herbaceous perennial vine in the Morning-Glory family (Convolvulaceae). It is found throughout most of Alabama. Southern Dawnflower grows in sand hills, in clearings in dry pine or hardwood forests, and on roadsides. It is a perennial with slender, elongate, rhizomatous roots. The stems are trailing or twining, pubescent, green or reddish-brown in color, and grow up to four feet in length. The leaves are alternate, petiolate, oblong to oblong-lanceolate in outline, entire, mucronate, and sparsely pubescent. They are often shallowly cordate at the base. Flowers are produced in few-flowered axillary corymbs. The peduncles are about twice the length of the subtending leaves with 2 small scale-like bracts. The sepals are ovate-lanceolate in outline and glabrous with ciliate margins. The flowers are campanulate to funnelform in shape, and white in color. The filaments of the five stamens are pubescent near the base The fruit is a capsule with four seed.--A. Diamond.
