Alamo vine is a white perennial morning glory that opens around noon and then closes before sunset. It is a Texas native found on stream banks, shell deposits, thickets, and other disturbed areas from Travis to Galveston to Val Verde counties; as well as from Florida to Texas and into South America. It colonizes by rhizomes, stolons, self-layering, and by its taproot in sandy, loamy, clay, caliche, shelly, and well-drained calcareous soils. It grows very easily from fresh seed.
