Montana’s high altitude and short season favor hardy herbs like sage and winter savory, making it essential to choose the Best Herbs To Grow In Montana carefully. Whether you’re in Bozeman, Billings, or Missoula, your garden can thrive with the right selections. This guide covers tough, cold-resistant herbs that survive frost and deliver fresh flavor all summer.
You don’t need a greenhouse or fancy equipment. Just a sunny spot, well-draining soil, and a little planning. Let’s walk through the top herbs that laugh at Montana’s weather.
Best Herbs To Grow In Montana
Montana’s climate is unique. Long, freezing winters and short, intense summers mean not every herb will make it. But many Mediterranean herbs actually love these conditions. They need less water and handle temperature swings well.
Below are the top performers. Each one has been tested by Montana gardeners and proven reliable.
Hardy Perennial Herbs For Montana Gardens
Perennials are your best bet. They come back year after year, saving you time and money. These herbs survive Montana winters with minimal protection.
Sage
Sage is practically indestructible. It thrives in poor soil and full sun. Once established, it needs very little water. The leaves get more flavorful after a light frost. Plant it once and you’ll have sage for decades.
Winter Savory
Winter savory is a compact, woody herb that stays green late into fall. It’s more cold-hardy than summer savory. Use it in stews and bean dishes. It also makes a great low hedge along garden borders.
Thyme
Thyme is another champion. Creeping thyme works as a ground cover, while upright varieties are better for harvesting. It tolerates drought and poor soil. In Montana, it often survives under snow cover without issue.
Oregano
Greek oregano is the hardiest type. It spreads slowly and produces intense flavor. Cut it back in late fall and mulch lightly. It will bounce back in spring before most other plants wake up.
Chives
Chives are the easiest herb for beginners. They grow in clumps and produce purple flowers in early summer. The leaves have a mild onion taste. They die back in winter but return reliably. Divide clumps every few years to keep them vigorous.
Lovage
Lovage tastes like celery but is much hardier. It grows into a large plant, up to 6 feet tall. Use the leaves in soups and salads. It dies back completely in winter but emerges early in spring.
Annual Herbs That Work In Montana’s Short Season
Some annual herbs need a little help. Start them indoors or choose fast-growing varieties. With the right timing, you can still get a good harvest.
Basil
Basil hates cold. But you can grow it if you start seeds indoors 6 weeks before the last frost. Transplant after soil warms up, usually in early June. Choose compact varieties like ‘Genovese’ or ‘Spicy Globe’. Harvest often to keep plants bushy.
Cilantro
Cilantro bolts quickly in heat. In Montana, plant it in early spring or late summer for a fall harvest. It self-seeds readily. Once you have it, you might never need to plant it again. The seeds (coriander) are also useful.
Dill
Dill grows fast and handles cool weather. Direct sow seeds in the garden after the last frost. It reseeds itself if you let some flowers go to seed. Use the leaves fresh and the seeds for pickling.
Parsley
Parsley is technically a biennial, but most gardeners treat it as an annual. It grows well in Montana’s cool spring and fall. Soak seeds overnight before planting to speed germination. Curly and flat-leaf types both work.
Summer Savory
Summer savory is an annual with a peppery, thyme-like flavor. It grows quickly from seed. Plant it in full sun after the frost danger passes. It’s a good substitute if you want a milder taste than winter savory.
Herbs That Need Extra Protection In Montana
Some herbs are borderline. They might survive with a little help. If you’re willing to experiment, try these.
Rosemary
Rosemary is not reliably hardy in most of Montana. But you can grow it in a pot and bring it indoors for winter. Or try ‘Arp’ rosemary, which is more cold-tolerant. Mulch heavily around the base if you leave it outside.
Lavender
English lavender varieties like ‘Munstead’ and ‘Hidcote’ can survive Montana winters. They need excellent drainage and full sun. Plant them on a slope or raised bed to prevent root rot. Snow cover actually helps insulate them.
Tarragon
French tarragon is not frost-hardy. But Russian tarragon is tougher, though less flavorful. If you want French tarragon, grow it in a container and overwinter it indoors. It’s worth the effort for its anise-like taste.
How To Plant And Care For Herbs In Montana
Success with herbs depends on a few key practices. Follow these steps to give your plants the best chance.
Choose The Right Location
Most herbs need at least 6 hours of direct sunlight daily. Pick a spot that drains well. Avoid low areas where frost settles. South-facing slopes or raised beds warm up faster in spring.
Prepare The Soil
Montana soil can be heavy clay or rocky. Mix in compost or aged manure to improve drainage. Herbs prefer slightly alkaline soil. If your soil is acidic, add a little lime. Test your soil pH if you’re unsure.
Timing Is Everything
Montana’s last frost date varies by region. In the mountains, it can be as late as June 15. On the plains, it’s usually around May 15. Check your local frost dates. Start tender herbs indoors 4-6 weeks before transplanting.
Water Wisely
Most herbs prefer dry conditions. Overwatering is a common mistake. Water deeply but infrequently. Let the soil dry out between waterings. Use drip irrigation or a soaker hose to keep leaves dry and prevent disease.
Mulch For Winter Protection
Apply a 2-3 inch layer of straw or leaves around perennial herbs after the ground freezes. This insulates the roots from temperature swings. Remove the mulch in early spring when new growth appears.
Harvest Regularly
Frequent harvesting encourages bushier growth. Pick leaves in the morning after dew dries. For the best flavor, harvest before flowers open. Cut no more than one-third of the plant at a time.

Common Mistakes When Growing Herbs In Montana
Even experienced gardeners make errors. Avoid these pitfalls to keep your herbs healthy.
Planting Too Early
Montana can have frost in late spring. Don’t rush to plant tender herbs outdoors. Wait until soil temperatures reach at least 60°F. Cold soil stunts growth and can kill seedlings.
Overwatering
Herbs like sage and thyme evolved in dry climates. Too much water causes root rot and weakens plants. Let the soil dry between waterings. In clay soil, be especially careful.
Ignoring Microclimates
Your yard has warm and cool spots. South-facing walls absorb heat and protect plants. North-facing areas stay cooler longer. Use these microclimates to your advantage. Plant tender herbs near a south-facing wall.
Not Hardening Off Seedlings
Seedlings grown indoors need time to adjust to outdoor conditions. Gradually expose them to sun and wind over a week. Sudden transplanting causes shock and stunted growth.
Skipping Mulch
Mulch is not just for looks. It regulates soil temperature, retains moisture, and suppresses weeds. In Montana, it also protects roots from freeze-thaw cycles. Don’t skip this step.
How To Extend The Herb Growing Season In Montana
You can get more out of your garden with a few simple techniques. These methods help you harvest earlier in spring and later in fall.
Use Cold Frames
A cold frame is a simple box with a glass or plastic lid. It traps heat and protects plants from frost. Place it over herbs in early spring or late fall. You can buy one or build it from old windows.
Try Row Covers
Floating row covers are lightweight fabrics that let light and water through. They add a few degrees of frost protection. Use them to extend the season by 2-4 weeks. They also keep insects away.
Plant In Containers
Containers warm up faster than ground soil. Move them indoors or to a sheltered spot during cold snaps. Use large pots to prevent roots from freezing. Bring tender herbs like rosemary inside for winter.
Choose Early-Maturing Varieties
Look for herb varieties with short days to maturity. For basil, ‘Genovese’ takes about 70 days. ‘Spicy Globe’ is even faster. For dill, ‘Bouquet’ matures in 60 days. Check seed packets for days to harvest.
