Whether you are a novice gardener or have years of experience, building on your knowledge of perennial herbs is essential.

And so, before we head to the eighteen best perennial herbs to grow in your garden, here are the answers to some of the frequently asked questions.
Frequently Asked Questions About Growing Perennial Herbs
Perennial herbs are plants that return every year without manual replanting. They grow back each year by self-seeding or from their underground root system. Most of them enter dormancy in the winter season to return in spring.
Will herbs come back every year?
Perennial herbs come back every year as they spread in their territory.
Which herbs can survive the winter?
When offered protection, mint, chives, parsley, oregano, thyme, and sage can survive the cold winter temperatures and still produce flavorful foliage. Use a cloche or cold frame to cover the herbs, pot them up, and relocate them to a sun porch or frost-free greenhouse.
Alternatively, place a thick layer of straw, shredded bark, or other coarse mulch to help with insulation, maintaining the ideal temperatures for the herbs to thrive.
Eighteen Best Perennial Herbs for Every Garden
Give these eighteen herbal species a try.

8 – Lovage:

- This cool-climate herb thrives in USDA hardiness zones 3-9 and exhibits a fast growth habit, meaning you can harvest it within a couple of months of planting.
9 – Marjoram:

- Parsley is a biennial in warm climates if given some winter protection. Though each plant may last only two years, it readily self-seeds and often becomes a permanent feature.
- It thrives in full sun but can take light shade.
- It’s a great companion plant to most edible annuals and perennials but particularly beneficial when grown alongside roses, carrots, tomatoes, and asparagus.
- Use it in sauces, soups, salads, and potato dishes.

- Plant it in spring from either divisions or seeds.
14 – Rosemary:
- Rosemary (Salvia Rosmarinus) is a perennial evergreen shrub with moderate growth, usually blooming in its second season post maturity.
- Its piney scent and pretty green needle-like leaves make it a lovely addition to any garden, mainly because it thrives even in poor soils.
- It will survive winter outdoors in mild climates, but you may want to bring it indoors during winter if you reside in a colder region.
15 – Sage:
- Sage (Salvia officinalis) is a low-maintenance, easy-to-grow perennial herb with a moderate growth rate, blooming during summer in spikes of blue-purple flowers.

- Also known as common, garden, lamb, spire, and mackerel mint, spearmint, a close relative of peppermint, belongs to the Mentha genus.
- Unlike peppermint, this herb has a mildly sweet, subtle flavor, ideal for complementing any dish, especially when you don’t want something taking over as the flavorful focal point.
- Spearmint’s biggest advantage over all the other mints is its resistance to verticillium wilt.
18 – Winter savory:
- Winter savory (Satureja montana) is a hardy perennial, quite bushy, with a zesty flavor.
- It’s often used in herbal teas, herb vinegar, herb butter, and other dishes.

The Takeaway: These Perennial Herbs Are Perfect for Your Garden
You need to offer these plants the right growing conditions and some TLC.
As with all plants, check your growing zones for tolerance in your area. Although some species might be perennial, they might not prefer cold temperatures. Thus, you may treat them as annuals.
Here are some quick tips for setting you up for success with your perennial herbs:
- Choose your favorites to try
- Decide on the planting location—it should be a spot allowing the plant’s optimal growth.
- Offer the plants adequate room, especially when transplanting. That’s the planting depth.
- Have companion plants in your herbal garden.
- Water your perennials regularly to help establish a deep root system.
- Deadhead your flower heads to help conserve the plant’s energy for new, healthy growth.
- Divide the plant(s) every few years to avoid overcrowding.
- Winterize your plants. If growing outdoors, consider mulching around the plant’s root system to protect it from below-freezing temperatures.
