Yes. Parsley is a biennial, which means it grows a plant the first year and sends up a seed stalk or flowers the second year. If grown in an area protected from excessively hot temperatures or excessively cold temperatures, parsley can be harvested well into the second year. When a flower stalk is initiated, remove it and continue harvesting the mature leaves. If parsley is forced to grow for long periods at temperatures above 90°F, growth is greatly reduced and death may occur. Parsley is cold-hardy and can overwinter in most areas. If planted too early in the spring, cold temperatures may cause it to send up a flower stalk during its first season of growth.
