There are two varieties of parsley used for herbs, one being the curly leaf and the other being the Italian, both grown in the Montreal Botanical Garden in Hochelaga-Maisonneuve in Montreal, Quebec. The Italian Parsley has flat leaves which many find the flavoring to be considerably stronger than the curly leaf.
