More on naturalization and invasiveness: Akebia quinata has a wide environmental tolerance and thrives in many different soil conditions. It seems to prefer warm conditions; young growth in spring is frost-tender, even on mature plants. This vine can invade many types of habitats: urban areas, forest edges, woodlands, wetlands, riparian zones, etc. It spreads mainly vegetatively (seed production is infrequent); dispersion is typically dependent on man assistance. In Belgium, five-leaf is commonly used as an ornamental; it is planted in gardens and public green areas but doesn't reproduce in the wild so far.

More on impacts: Under suitable environment conditions, Akebia quinata grows extremely quick (6 to 12 meters per year). It forms dense curtains of interwined stems that cover, outcompete and kill ground layer and shrub vegetation; it may also overtop canopy trees. Once established, its dense growth prevents the establishment of native species and has a strong influence on the availability of light, water and nutrients.
