This Italian flat-leafed parsley has, of course, flat leaves, which distinguish it from the better-known curly-leafed parsley. At first the foliage might be easily confused with cilantro. However, its flavor is distinctly parsley, and it is favored for its deep flavor, which some say holds up better in cooking than curly parsley. This is a great plant for containers, especially for fall and winter. It is also more tolerant of hot weather than curly parsley (which can struggle during the peak of summer) and is frost tolerant.
