The answer to this question depends on what your winters are like. In the Southern US, for example, the Pothos may carry on without a problem through their winter period. The North is a whole different story. If you want to be sure before you buy, you can refer to the USDA Zoning Guide. It shows you what plant survives best in different locations. Of course, those are not hard-and-fast borders, but the research is worthy of your attention. There is nothing more disappointing than putting effort into a Pothos and having it die within the first year.
