HERBS, BIENNIAL

Biennial herbs take two years to complete a life cycle. Usually, they grow leaves, stems and roots in the first year of growth, die back for the winter and begin flowering and developing seeds the second year. It is a good idea to develop a cycle each year so that you can continue harvesting. Sometimes they may develop more quickly, in harsh conditions and can go through a two year life cycle in months. These plant do not tolerate cold or frost and are usually treated as annuals. Do not transplant until danger of frost is past.

HERBS, PERENNIALS
Perennial herbs will live for more than two years. Although they grow better from root stock better than from seeds, they usually produce flowers and seeds. Perennials tend to be harder to grow from seeds than annuals. Many perenials can be rooted or propagated by division. Perennials die back in the winter and grow back from the roots. In very harsh climates, this plant might be treated as an annual.
