Is Parsley a Perennial or an Annual? Perennials are plants that grow back each year, and annuals are plants that die after one season. Parsley is actually a biennial.

In reality, parsley is classified as a biennial, meaning it completes its lifecycle in two years. This classification is crucial for understanding how parsley grows. In its first year, parsley focuses on producing lush foliage, while the second year is all about flowering and seed production.
