Parisian Carrots are an all Heirloom, Non-GMO variety. These grow small and round and are packed with carrot flavor. With nice 6 to 8 inch tops, these are ready in 60 to 80 days--depending on the size of carrots that you like. As with most carrots, these are cold tolerant; that means they will grow in any zone in the USA. To our farmers market friends, these make the cutest bunches ever! Happy growing!!!
