Parsley is a hardy, biennial that is grown and treated like an annual. It is the most widely grown herb for both garnish and flavoring. There are two distinct types of parsley: moss-curled and flat-leaf. Moss-curled forms a rosette of leaves that are finely cut and tightly curled. It is often used for garnish. Flat-leaf produces a rosette of leaves that are flat and is the preferred parsley for cooking as it has more flavor. Parsley is grown from seed planted in the spring. Because it is slow to germinate, it is suggested to soak the seeds in water overnight prior to planting. A helpful aid to marking the rows of newly seeded parsley is to plant radish seeds in with the parsley seeds. The radish will germinate quickly to mark the row where parsley is also planted, and this helps prevent parsley seedlings from being cultivated out accidently. Parsley prefers a moderately rich, moist, well-drained soil and will grow in a partially shaded area. Parsley will overwinter but the following season results in a plant that produces a seed stalk (bolting) and leaves that are very tough and bitter. This is why new plants are started each season. When transplanting parsley take extra care not to damage the taproot.
