I want to start a pot garden of herbs-
where can i purchase fresh herbs for re-potting
in SouthEast Florida
Suggest an internet search for your area. Locally herb plants are not as varied as to choices, so you may also want to consider seeds as well as rooted plants shipped from companies that offer a large assortment. Richters is one, but is in Canada.
There are regional and state-based forums on garden web. If you are looking specifically for local nurseries, try one of those forums if you don't get any answers here.
