Muehlenbeckia complexa

Muehlenbeckia complexa, commonly known as maidenhair vine, creeping wire vine, lacy wire vine, angel vine, mattress vine, mattress wire weed, necklace vine, and wire vine, is an ornamental plant in the Polygonaceae family, which is native to New Zealand. It is quite vigorous and probably the best species for trimming and topiary. It is semi-deciduous, growing to 15 ft (4.5 m) or more up suitable supports, and produces swollen white berries with black seeds. This species can become quite weedy in suitable climates if not restrained.
