What is hardneck garlic?
Garlic comes in many different varieties, and most people picture it as one thing when it is really a whole taxonomic hierarchy. Hardneck garlic is the branch known botanically as Allium sativum var. ophioscorodon. Its defining trait is the scape, a true flowering stalk that rises from the center of the plant in early summer. That central stalk is where the name comes from, and it is also why hardneck cloves grow larger and fewer, arranged in a single ring around the stem.
Because each clove is bigger, hardneck is easy to peel and prized in the kitchen for its bold, hot, complex character, which shows up most when the garlic is eaten raw. The trade-off is storage life. Hardneck keeps a few months less than softneck garlic, so it is best enjoyed through fall and winter rather than held all the way to the next harvest.
Hardneck vs softneck garlic
The two types behave differently in the ground, the kitchen, and the pantry. Here is how hardneck compares.
| Hardneck | Softneck | |
|---|---|---|
| Scape | Yes, a true flowering stalk | None |
| Cloves | Larger, fewer per bulb | Smaller, more per bulb |
| Flavor | Bolder and more complex, best raw | Milder, everyday cooking |
| Storage | 4 to 7 months | 8 to 10 months |
| Cold needed | Required, a real winter | Helpful but not required |
| Best climate | Colder zones | Wide range, milder winters too |
| Braiding | No, the stalk turns woody | Yes |
The hardneck garlic we grow
We grow two true hardneck subgroups plus a small, supply-limited run of two weakly bolting types that plant like hardneck.
Growing hardneck garlic
Hardneck is a fall crop. You plant cloves in October or November, a few weeks before the ground freezes, so the roots establish before winter. Our full garlic growing instructions walk through spacing, depth, and mulch, and the garlic planting calculator tells you how many pounds your beds will need.
The cold itself matters. Hardneck has a strict vernalization requirement, roughly forty or more days below 40°F, to trigger bulbing, which is why it does best in colder zones. If you are not sure your winter is cold enough, the garlic zone finder checks your ZIP against your USDA zone and frost dates. In early summer the plant sends up its scape. Cut it about four inches above the last leaf so no hollow stem is left to collect water, which pushes energy back into the bulb for a bigger head and gives you scapes to cook.
After harvest, cure the bulbs in a dry, airy spot and leave at least five papers intact. Stored at 55 to 65°F with moderate humidity, hardneck holds for several months. Keep it out of the refrigerator, since the swing from cold back to warm is the signal that tells a clove to start growing.
Why seed garlic from Basaltic Farms
Triple certified organic
Every bulb we sell is certified three ways, CCOF, USDA Organic, and the Real Organic Project. The paperwork is real and so is the practice behind it.
High elevation, volcanic ground
Our fields sit at 3,300 ft in the Fall River Valley on soil laid down by ancient basalt flows. Cold winters and mineral-rich ground suit garlic well.
Sorted by bulb size
We grade by bulb size, not clove count. The largest bulbs ship first, first come first served, so early orders get the best seed.
Shipped for fall planting
Orders ship starting in September so your seed arrives cured, intact, and ready to go in the ground in October and November.
Plan your planting
Match varieties to your growing zone, figure out how many pounds your beds actually need, and check bulk pricing before you commit. A few minutes of planning saves a lot of guessing in October.
What people say
Hardneck garlic questions
What is hardneck garlic?
Hardneck garlic produces a true flowering stalk called a scape and grows larger cloves with fewer per bulb. It carries the boldest raw flavor of any garlic. Our hardnecks are Porcelain, like Music, and Purple Stripe, like Chesnok Red.
What is the difference between hardneck and softneck garlic?
Hardneck grows a scape, larger cloves, bolder raw flavor, and needs real winter cold. Softneck has no scape, more but smaller cloves, milder flavor, stores longer, and adapts to a wider range of climates. Most gardeners grow some of each.
Which hardneck varieties does Basaltic Farms grow?
Our true hardnecks are Music, a Porcelain, and Chesnok Red, a Purple Stripe. We also grow small, supply-limited runs of Thai Purple, a Turban, and Korean Mountain, an Asiatic, two weakly bolting types that plant much like hardneck.
What is a weakly bolting hardneck?
A weakly bolting type may or may not send up a scape, and when it does the stalk is shorter and less reliable than a true hardneck's, depending on the season and climate. The Asiatic and Turban groups behave this way. Our Korean Mountain and Thai Purple sit here, and because they plant and grow much like hardneck, we group them with ours.
Will hardneck garlic grow in my climate?
Hardneck needs a real winter, roughly forty or more days below 40°F, to set its heads, so it does best in colder zones. Enter your ZIP in our garlic zone finder to see whether hardneck, softneck, or both fit your winter.
When do I plant hardneck garlic?
Plant in fall, usually October or November, a few weeks before the ground freezes so roots establish before winter. The cold months provide the vernalization hardneck needs, and the plants resume growth in spring for a summer harvest.
What are garlic scapes and should I cut them?
The scape is the curling flower stalk hardneck sends up in early summer. Cut it about four inches above the last leaf so no hollow stem collects water. That sends energy back into the bulb for a bigger head, and the scapes are a delicious crop.
How long does hardneck garlic store?
Hardneck keeps about 4 to 7 months at 55 to 65°F with 60 to 70 percent humidity and good airflow. Leave at least five papers intact and do not refrigerate, since the cold then warm swing is what tells a clove to start growing.
When can I order and when does it ship?
Pre-orders open March 1 every year and the premium varieties tend to sell out first, so ordering early locks in what you want. Everything is harvested and cured over summer and ships in September so it arrives in time for fall planting.
