Perennial herbs should be given a permanent location in the garden where they can grow undisturbed year after year. Perennial herbs require periodic division to remain healthy and productive. Divide perennial herbs when they show decline, become woody or overgrown, or when you want new starts.

Common perennial herbs are angelica, burnet, chive, comfrey, garlic, horseradish, lamb’s ear, lavender, lemon balm, lovage, mint, oregano, rosemary, rue, sage, tansy, tarragon, thyme, winter savory, and yarrow.
