Perennial herbs are those that live and grow for multiple years, often coming back each growing season without needing to be replanted. Many popular culinary and aromatic herbs fall into this category, especially those in the mint family.
Common Perennial Herbs
- Mint family (Lamiaceae):
- Rosemary
- Oregano
- Thyme
- Sage
- Lemon balm
- Marjoram
- Anise hyssop
- Mint (various types)
- Other notable perennials:
- Lavender
- Lemon verbena
- Tarragon
- Chives
- Bay laurel (can grow like a small tree)
These herbs typically grow back year after year, sometimes developing woody stems and growing into bushy plants. They thrive in moderate climates and can be perennial in USDA zones ranging roughly from 3 to 10 depending on the herb and local conditions. Some, like rosemary, may need winter protection in cooler zones
