Does parsley regrow itself?

Parsley is actually a biennial. This less common classification means that the plant only comes back after two gardening seasons — just enough time to produce leaves, go to seed, and develop a substantial taproot. As a biennial, the parsley plant offers delicious leaves its first year, and goes to seed its second year.
