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.[1] 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.

In its native environment it plays a key role sealing human and natural disturbances on the forest edge. It also suppresses the growth of introduced weeds, such as blackberry, and promotes increased insect diversity.[2] Its Māori name is pohuehue, although the same name also applies to some other climbers such as Muehlenbeckia australis.[3]

It is naturalised in Western Australia.[4]

Since 1995 or earlier, it has been a problematic invasive species in the Golden Gate National Recreation Area[5] including Lands End, San Francisco[6] and the Presidio of San Francisco[7] and eradication requires 3–5 years monitoring and maintenance.[8]
