Merremia dissecta, commonly known as the Noyau vine, Alamo vine, or white morning glory, is a vigorous twining perennial climber in the morning glory family (Convolvulaceae), admired for its striking foliage and large, showy blooms. Native to the Americas but naturalized in many warm regions worldwide, it thrives in sunny, open habitats such as roadsides, fences, thickets, and disturbed areas, where it can quickly scramble over other vegetation. The plant is easily recognized by its deeply lobed, palmate leaves, which give it a finely cut, ornamental texture, and by its conspicuous funnel-shaped flowers that are white to pale pink with a dark reddish-purple throat, blooming from summer into fall. These blossoms not only provide visual interest but also attract bees, butterflies, and other pollinators. Following flowering, the plant produces rounded, capsule-like seed pods that further aid its spread, sometimes allowing it to become weedy or invasive outside its native range. Merremia dissecta is valued in gardens and landscapes for its fast growth, ability to cover trellises, fences, or arbors, and its lush tropical appearance, though its vigorous habit requires management in some settings. With its combination of delicately cut leaves, large flowers, and ecological contributions to pollinator support, this vine offers both ornamental beauty and natural resilience in warm-climate plantings.
