Discussion

Euonymus fortunei is widely planted as an ornamental and has escaped widely. Plants grow horizontally until they encounter a vertical surface like a rock, wall, or tree, which they then climb using adventitious roots. They sometimes form dense mats over other vegetation, excluding other plants.
