A plant that lives for more than two years, often many more, it can be herbaceous, like mint which dies down each autumn and then grows again in spring, or evergreen like rosemary where the leaves stay green all year round. Some perennials can be tender such as lemon grass and requires protection from the winter weather.
Please note that not all herbs are available year round due to seasonality - you can also visit our currently available category, which has been filtered to view perennial herb plants that are in season now.
