This northern Italian heirloom grows 12-18″ tall (always on the taller side for me). Tall Gigante plants are vigorous growers and have very big, deep green shiny leaves with an exceptionally mellow and sweet fuller flavor than standard plain Parsley. You will find that curly parsley is hardier than flat parsley, so be sure to have some of both in your garden. In the middle of winter, you’ll almost always find a few sprigs of the curly variety waiting to be harvested. Enjoy your flat parsley before the coldest weather of the winter–although it should be fine through Christmas.
