Curly Parsley (Petroselinum crispum): Classic Garnish and Culinary Herb

Overview

Curly parsley (Petroselinum crispum) is a biennial herb grown as an annual for its decorative, tightly curled leaves. Native to the central Mediterranean, it is the classic garnish herb, but also adds fresh, mild flavor to countless dishes. In its second year, it produces umbels of tiny yellow-green flowers.

Botanical Description
