If you are looking for a fast climber that can tolerate both sunny and shady environments, you will find very few plants that are as fitting as Boston ivy. We’ll start right off the bat with an interesting fact and we’ll tell you this is the plant that inspired the term Ivy League, as it was often seen growing on many prestigious campuses.

Many gardeners use this plant to beautify the façade of buildings, but very few people know that Boston ivy is, in fact, part of the same Vitaceae family and more related to the grapevines than the ivies. This, and the fact that it originates from eastern Asia – predominantly Japan – has earned it many names, such as Grape Ivy, Japanese Ivy, and Japanese Creeper.

You can successfully grow Boston ivy both outdoors and indoors, but you will have to be cautious and prune it often, as it tends to stretch out very fast and cling to anything it encounters. All in all, it makes for a wonderful climber and ground-cover plant, as well as a nice addition to any room that requires a touch of nature.

When it reaches maturity, Boston ivy can climb as high as 50 feet, or in some instances even more. Its green, lush foliage can best be seen during summer, but the Japanese Creeper is a spectacle of colours year-round. In spring, new leaves are of a reddish colour, turning green during the summer and then slowly transitioning back to shades of red during the fall – a feast for the eyes and, because of its small fruits, for the birds as well.
