Hardneck Garlic
Allium sativum var. ophioscorodon
Better flavour, bigger cloves, a bonus scape crop, and it will not keep past midwinter.

Hardneck suits a cold winter
Hardneck varieties - Music, German Extra Hardy, Chesnok Red, rocambole and porcelain types - need a real cold period to form proper bulbs, which makes them the better choice in zone 6b/7 and colder. Softneck often produces small or unsplit bulbs this far north.
Plant in autumn
Four to six weeks before the ground freezes, October into November. The clove roots in autumn, sits through winter, and races away in spring. Spring-planted garlic produces small bulbs at best.
Break the head late, plant tip up
Separate the bulb into cloves just before planting - cloves broken early dry out. Plant the largest cloves only, pointed end up, two to three inches deep, six inches apart. Save the small inner cloves for the kitchen.
Mulch heavily
Four to six inches of straw after planting. It prevents frost heaving, moderates soil temperature, and suppresses the spring weeds that garlic - being upright and sparse - competes with badly.
Cut the scapes
In June, hardnecks send up a curling flower stalk. Cut it once it makes one full loop. Leaving it on reduces bulb size by a fifth or more. The scapes themselves are excellent - grill them, or make scape pesto - which is a real advantage hardneck has over softneck.
Feeding and water
Nitrogen in early spring when growth resumes, and again a month later. Stop feeding by late May. Water steadily through spring, then stop entirely two to three weeks before harvest so the wrappers dry and cure properly.
When to lift
When the lower three or four leaves have browned but five or six above are still green - each green leaf is a wrapper layer around the bulb. Waiting until all leaves brown means the wrappers have rotted and the cloves split apart, which ruins storage. Loosen with a fork; never pull by the stem.
Curing and storage
Hang whole plants in a dry airy shaded place for three to four weeks until the necks are tight and papery. Then trim roots and tops. Hardneck stores four to six months - noticeably less than softneck, because the stiff neck does not seal as well. Store at 55-65F, dry, and not in the fridge, which triggers sprouting.
Save your own seed
Replant your largest cloves each autumn. Garlic adapts to local conditions over a few seasons and home-saved stock generally outperforms bought.
