Small White Morning Glory, Whitestar, Pitted Morningglory - Ipomoea lacunosa


Family: Convolvulaceae - Morning-glory family Genus Common Name: Morning Glory Native Status: Native
Ipomoea lacunosa - Small White Morning Glory, Whitestar, Pitted Morningglory. This pretty little white morning glory is found in most of the eastern half of the United States, west to Texas and Kansas; from Florida north to New York. All Ipomoea species, including Ipomoea lacunosa are prohibited as noxious weeds in Arizona and Arkansas (Ipomoea lacunosa isn’t found in Arizona.) While Small White Morning Glory is a United States native plant, it is not native in its entire range. As expected for such a disjointed population, it is not native to California, where it is currently found in only one county.

The Morning Glory name is applied because these flowers, which can be especially glorious when large numbers are blooming, will close up later in the day as the bright sun shines on them. While most morning glories seem to close tightly, Ipomoea lacunosa just curls its lips - the corolla lobes.

Found in:
AL, AR, CA, DC, DE, FL, GA, IA, IL, IN, KS, KY, LA, MA, MD, MO, MS, NC, NJ, NY, OH, OK, PA, SC, TN, TX, VA, WV

Ipomoea lacunosa also goes by the common name Whitestar - the reason obvious from this photo. The anthers are usually a purple-pink. The blossom is sometimes pink.

The inflorescence of Ipomoea lacunosa will have 1 to 3 flowers, each no more than an inch long and less than that across. The pedicel is quite short, and the peduncle is shorter than the leaf petiole, which may be sparsely hairy or glabrous. The lanceolate sepals may be somewhat hairy.

The Ipomoea lacunosa vine, which can be up to about 10 feet long, does not have tendrils, but the end of it can look tendril-like in its clockwise spiral as it seeks something on which to climb.
