Alaska’s short summers and long winters limit perennial herbs to hardy choices like chives, sorrel, and lovage for reliable growth. If you’re gardening in the Last Frontier, you need plants that can survive freezing temperatures and come back year after year. Common Perennial Herbs In Alaska are not just a dream—they’re a practical reality for any gardener willing to choose the right varieties.
Perennial herbs save you time and money. Once planted, they return each spring without replanting. They also handle Alaska’s unique climate better than many annuals. Let’s look at the best options for your garden.
Why Perennial Herbs Work In Alaska
Alaska’s growing season is short, but perennial herbs are built for it. They start growing early in spring, often before the last frost. Their deep roots help them survive winter freezes.
These herbs also need less care than annuals. You plant them once, and they keep producing for years. That’s a big deal when you have limited time for gardening.
Another benefit: perennial herbs attract pollinators. Bees and butterflies love them. This helps your whole garden thrive.
Top Common Perennial Herbs In Alaska
Here are the most reliable perennial herbs for Alaskan gardens. Each one has been tested by local gardeners and proven to survive.
Chives
Chives are the easiest perennial herb for Alaska. They grow in almost any soil and handle cold well. You can plant them in spring or fall.

How To Plant Common Perennial Herbs In Alaska
Planting perennial herbs in Alaska requires some planning. Follow these steps for success.
- Choose a sunny spot. Most herbs need at least 6 hours of sun daily.
- Prepare the soil. Add compost or well-rotted manure. Herbs prefer soil that drains well.
- Plant in spring after the last frost. In Alaska, this is usually late May or early June.
- Space plants properly. Give them room to grow. Crowding leads to disease.
- Water well after planting. Keep the soil moist but not soggy.
- Mulch around plants. This helps retain moisture and protects roots in winter.
You can also plant in fall for some herbs. Chives and mint do well with fall planting. But spring is safer for most varieties.
Caring For Perennial Herbs In Alaska
Once planted, perennial herbs need regular care. Here’s what to do.
Watering
Water deeply but less often. This encourages deep root growth. Most herbs need about 1 inch of water per week.
Check the soil before watering. Stick your finger in the ground. If it feels dry an inch down, it’s time to water.
Fertilizing
Herbs don’t need much fertilizer. Too much can reduce flavor. Use a balanced, slow-release fertilizer in spring.
Compost tea is a good option. Apply it once a month during the growing season.
Pruning
Prune herbs regularly to encourage bushy growth. Remove dead or damaged leaves. Cut back plants in fall after the first frost.
For woody herbs like sage and thyme, prune in early spring. This removes winter damage and promotes new growth.
Winter Protection
Alaska’s winters are harsh. Protect your herbs with mulch. Apply a thick layer of straw, leaves, or wood chips after the ground freezes.
For tender herbs like lavender, use a winter cover. Burlap or row covers work well. Remove them in spring when the weather warms.
Common Problems With Perennial Herbs In Alaska
Even hardy herbs can have issues. Here are common problems and solutions.
Winter Kill
Some herbs die in winter despite being perennials. This often happens with sage and tarragon. Protect them with extra mulch or move them to a sheltered spot.
If a plant dies, replant in spring. Choose a hardier variety next time.
Poor Drainage
Alaska’s soil can be heavy clay. This leads to root rot. Improve drainage by adding sand or organic matter. Raised beds also help.
Pests
Herbs have few pests in Alaska. Aphids and slugs are the main problems. Wash aphids off with water. Use beer traps or diatomaceous earth for slugs.
Disease
Powdery mildew can affect herbs in humid conditions. Space plants for good air flow. Water at the base, not on the leaves.
Harvesting And Using Perennial Herbs
Harvest herbs regularly for the best flavor. Pick leaves in the morning after the dew dries. This is when oils are strongest.
For most herbs, cut about one-third of the plant at a time. Leave enough for regrowth. Stop harvesting by late summer so plants can prepare for winter.
Use fresh herbs in cooking. You can also dry or freeze them for winter use. Drying works well for thyme, oregano, and sage. Freezing is better for chives, mint, and sorrel.
Best Companion Plants For Perennial Herbs
Pair herbs with other plants for a healthier garden. Here are good companions.
- Chives with carrots and tomatoes
- Mint with cabbage and broccoli
- Thyme with roses and strawberries
- Sage with beans and carrots
- Oregano with peppers and eggplant
Avoid planting mint near other herbs. It spreads too fast and can take over.
Where To Buy Perennial Herbs In Alaska
Local nurseries are the best source. They carry varieties that are proven in your area. Look for plants labeled as hardy to zone 3 or 4.
Online nurseries also ship to Alaska. Check for cold-hardy varieties. Order early in spring for the best selection.
You can also start herbs from seed. Chives, sorrel, and lovage grow easily from seed. Start them indoors 6-8 weeks before the last frost.
