Centipede Plant Muehlenbeckia

Muehlenbeckia is a genus of plants, in the Pologonaceae (knotweed) family.  They are related to buckwheat and are native to Australia, New Zealand, New Guinea and islands in the Indian Ocean as well as a few that are native to Central and South America. However, they have been introduced to gardens all over the world. Unfortunately, some of the species a very weedy and have become a problem in their new homes.

All of the species are characterized by thin stems leading to the myriad of common names referring to climbing, wire, creeping, matted and so on. Some are prostrate and make tangled mats as much as three feet across. Some twine around nearby plants and can reach as high as 30+ feet off the ground. These climbers can become very heavy and cause damage to the supporting tree or structure.

All of the plants have smallish, green leaves. Some are semi-evergreen while others are deciduous. All bear flowers that range in color from white to yellow to green and all the shades in between. Some of the flowers are nearly invisible while others are quite eye catching. Sometimes there is an attractive fruit.

The smallest of them, with their thin stems, make good rock garden plants or they grow well in containers either outdoor on a patio or indoors as a houseplant. Their trailing habit makes them especially attractive dangling down from a hanging basket. The taller ones could make an interesting central planting in a bed.

Many of the species originate in coastal regions and can withstand salt and spray. Some come from mountain areas and can be hardy as far north as the North Western states. A few can survive near freezing temperatures and many can survive to Zone 11.

This appears to be a group of plants with something for everyone. But – remember that a number of them are invasive. Check carefully before you buy. 

Insects, Diseases, and Other Plant Problems:  Some species of this genus can be very weedy and aggressive.  Fungal problems can occur in poorly drained or wet soils.
