Snapdragon Vine, Snapdragon Maurandella, Vine Blue Snapdragon, Violet Twining Snapdragon
Maurandya antirrhiniflora (Asarina antirrhiniflora)


Snapdragon vine rambles, sprawls and climbs its way on limestone hills and sandy dunes through assorted shrubs from the dry salt marshes and beach areas of the southern Texas coast through the Rio Grande Plains and into the Trans-Pecos at elevations of 1500 to 6000 feet, and farther through Arizona, New Mexico and California and south into Mexico. The extensively twining stems bear thumbnail-sized, arrowhead-shaped, medium green leaves accented by numerous scattered periwinkle blue baby snapdragon-like flowers highlighted by a yellow throat. Ornamentally, snapdragon vine is an up-close vine, hardly showy from a distance, its fragile beauty best appreciated near an entry or garden bench, clambering up a small trellis or dangling over a limestone boulder. Although it is not winter hardy in much of Texas, it grows so quickly from seed in full sun or part shade, that it may be used as an annual in a wide range of soils, given good drainage. Rain or irrigation will promote faster growth and extend its blooming season. It is not unusual for snapdragon vine to re-seed itself the following year.
