Muehlenbeckia - Wire Vine, Lignum
Gardeners know Matted Lignum as an effective ground cover. When prostrate, the plant forms a dense mat, up to 4 inches, of tough, woody vines. "Lignum" refers to the tough vines, as does the name, Creeping Wire Vine. The name, Mattress Vine, refers to the density of the mat. It tolerates foot traffic quite well. It is also excellent for controlling erosion in your landscape.
The small, evergreen leaves are bronze in color from fall to spring. In addition to its use as a ground cover, it's excellent for container gardens and hanging baskets, topiaries, and cascading over walls.
