Perennial herbs are commonly used in everything from culinary applications to alternative healing, so knowing some of the best options is wise if you want to live a healthier life!
What are Perennial Herbs?
A perennial herb is an herbaceous plant that grows for more than 2 years, as opposed to annual or biennial plants. Some of the most common perennial herbs include basil, parsley, and cilantro. Most perennial plants flourish in the spring and summer, bearing their seeds, fruit or flowers, and then die in the cold of autumn and winter. However, from their roots, they are able to return to life the following spring. For this reason, perennial plants are often preferred by gardeners and herbal enthusiasts. 
There are a few dozen perennial herbs, some of which are frequently used in kitchens around the world. If these herbs grow in more tropical or warm climates, they may grow throughout the year, but in temperate and colder climates, they typically go dormant or die in the winter months.
