I love the fact that I can plant a herb plant and it will be there next year. Here are a few of my favorite Perennial Herbs.
Chives and Garlic Chives: Chives: often grow their spiky onion favored leaves in early spring..these can be picked or cut through spring. In May they will grow many purple-pink flowers these can be eaten in salads. Garlic Chives: These produce flatter garlic flavored leaves which can be cut from April to late autumn they grow white flowers in August which can be eaten in all sort of dishes.
Lovage: The leaves of this has a celery taste. Harvest time March- November
Mint: This can have a minty or fruity favor such as apple mint. This starts growing early spring and dies back late fall.
Sorrel: This has pale green leaves like spinach but has a lemon flavor. This starts growing in early spring and you should have the herbs leaves until late summer. If it gets to hot it will begin to die back early.
