I really don't recommend putting this anywhere that you do not want it to spread. This plant can become invasive in the wrong area, so I really advise against this. Here is an article for more information on the plant: https://www.gardeningknowhow.com/ornamental/shrubs/plumbago/growing-plumbago-plants.htm
