Muehlenbeckia complexa is part of the Polygonaceae family and its native range is Lord Howe Island to New Zealand where it grows as a scrambling shrub primarily in the temperate biome. This plant consists of wiry vines that create a delicate mat with rounded leaves. Its considered a fast-growing species which usually spreads by layering. Genus name honours Heinrich Gustav Mühlenbeck, a German-Swiss physician and botanist. The specific epithet is from the Latin complexa, meaning tangled. Light: Muehlenbeckia complexa thrives in full sun to partial shade. In the UK, a location with ample light will encourage more compact growth. While it can handle some shade, growth might become less dense. Water: The soil should be kept consistently moist but not saturated, particularly during the active growing season (spring and summer). Allow the upper inch of soil to dry slightly between waterings. Ensure good drainage. Soil: It prefers soil that drains well. A general-purpose potting compost is suitable for containers, and in borders, it tolerates various soil types provided they do not become waterlogged. Fertilising: Feed with a balanced liquid fertiliser every four to six weeks during the growing season (spring and summer). Reduce or stop fertilising during the autumn and winter months. Temperature: Muehlenbeckia complexa is reasonably hardy for many parts of the UK, often tolerating temperatures down to around -5°C if protected. In colder regions or during harsh winters, some leaf loss might occur, or it may benefit from winter protection. Indoors, it prefers cooler to moderate room temperatures. Humidity: Typical UK humidity levels are generally sufficient. It does not require high humidity. Growth Habit: It has a sprawling, trailing, and sometimes climbing growth pattern, forming a dense tangle of stems. It can be quite vigorous in suitable conditions. Pruning: Trim regularly to maintain its shape and density, especially if grown in containers or as a groundcover. It responds well to trimming. Toxicity: Muehlenbeckia complexa is generally considered safe for people and animals. However, it is always a good practice to prevent ingestion.
