Cape ivy is native to parts of Africa, where it exists without significant ecological concern. In contrast, it has found its way to various regions on other continents, often in temperate areas, and has settled in these new ecosystems. While cape ivy is cultivated for certain desirable traits, it is sometimes thought to be spreading in a manner that may have an impact on ecosystems, particularly in some introduced areas where its growth can be robust and persistent. The distribution of cape ivy has led to its classification as invasive in certain regions, which indicates that, while not universally disruptive, it could be affecting local flora in those places.

Cape ivy originates from South Africa. This plant has gained the description of a weed due to its fast-growing and tenacious nature. In an environment suited to its growth, i.e., a warm, temperate climate, it spreads rapidly, causing significant damage to native plants and ecosystems by smothering them under its dense foliage. As a garden plant, its lush, pretty appearance can be deceiving, but remember, it will quickly take over your garden if not rigorously controlled. The plant's main method of propagation is through stem fragments. This means that even a small piece of the plant, if broken off and left in the soil, can grow and spread into a new plant, making it particularly challenging to eradicate completely.

The optimal time to address the spread of cape ivy is during its active growing season and before it sets seed. Removing or controlling cape ivy is best done in late winter to early spring.
