Container gardens are nothing more than a collection of pots, planted with whatever you like.
They can be mixed and matched, sleek and collected, for an eclectic group of plants, or a particular purpose.
Here are some ideas to get you started. There are no rules with choosing which type of container to use although vegetables prefer a bit more soil. Succulents are happy with almost none.
That is just the tip of the iceberg - there is a multitude of other ideas for your container garden all around.
Pinterest alone has more possibilities than you'll ever be able to use, like the gorgeous option below.
