Garlic (Allium sativum) divides into two main subspecies with fundamental differences in how they grow, how they store, what they taste like, and which climates suit them. Most grocery store garlic is softneck. Most of what serious home growers and farmers market vendors grow is hardneck. The differences are real and worth understanding before you plant.

I don't grow garlic at my Long Island property currently — the deer pressure and lack of a dedicated vegetable enclosure make alliums a frustration — so this guide draws primarily on University Extension research rather than personal experience. I grow ornamental alliums extensively, but that is a different plant entirely.

Botanical Distinction

Per Penn State Extension, Allium sativum divides into two subspecies:

• A. sativum var. ophioscorodon — hardneck (also called ophioscorodon or top-setting garlic)
• A. sativum var. sativum — softneck (also called artichoke or silverskin garlic)

Hardneck garlic produces a rigid central stem (the "neck") that extends from the bulb upward and terminates in a scape — a curling flower stalk that produces small bulbils at its tip. Softneck garlic does not produce a scape; its leaves and outer skins remain soft and pliable, which is why it can be braided.

Climate Suitability

This is the most important factor for most home growers in the northern US.

Per Cornell Cooperative Extension, hardneck garlic requires cold winter temperatures to properly vernalize — the cold period that triggers bulb differentiation and development in spring. Most hardneck varieties need 6–8 weeks of temperatures below 40°F to form well-developed, multi-clove bulbs.

In USDA zones 3–7 (including most of the Northeast, Midwest, and Pacific Northwest), hardneck garlic overwinters reliably and performs excellently. In zones 8–9, the winters are too warm for consistent vernalization, and softneck varieties that tolerate mild winters are the better choice.

Per Clemson HGIC, softneck garlic is recommended for gardeners in the Southeast and other mild-winter regions because it does not require as pronounced a cold period. It will also grow in northern zones but typically produces smaller bulbs than hardneck varieties in those climates.

Hardneck Varieties

Per Cornell Cooperative Extension, hardneck garlic breaks into several groups, each with distinct flavor profiles and storage potential:

Rocambole: Rich, complex flavor with a slight heat; papery outer skin that peels easily. Poor storage (3–4 months). Best flavor of all garlic types. Varieties include 'German Red', 'Killarney Red', 'Spanish Roja'.

Porcelain: Large bulbs with 4–6 cloves; white papery skin; sharp raw flavor that mellows significantly when cooked. Better storage than Rocambole (5–7 months). Varieties include 'Music', 'German White', 'Romanian Red'.

Purple Stripe: Intense garlic flavor; distinctive purple striping on outer skin; good roasting garlic. Storage 4–6 months. Varieties include 'Chesnok Red', 'Siberian'.

Marbled Purple Stripe: Closest to wild garlic; most cold-tolerant hardneck types; very large cloves. Varieties include 'Khabar', 'Metechi'.

Softneck Varieties

Per Penn State Extension, softneck garlic breaks into two main groups:

Artichoke: Large bulbs with multiple layers of cloves (up to 20 per bulb, in irregular arrangement); mild to moderate flavor; excellent storage of 9–12 months. The dominant type in commercial production. Varieties include 'California Early', 'Inchelium Red', 'Lorz Italian'.

Silverskin: Smaller bulbs with more uniform flavor; longest storage of any garlic (10–12 months); used primarily for garlic powder and dehydrated products. Varieties include 'Nootka Rose', 'Silver White'.

Scapes: A Hardneck Bonus

Hardneck garlic produces scapes — curling green flower stalks — in late spring/early summer, typically 2–3 weeks before bulb harvest. Per Cornell Cooperative Extension, scapes should be removed when they make their first full curl: removing them directs the plant's energy into bulb development rather than seed production, increasing final bulb size by 10–20%.

Scapes are also edible — with a milder, slightly sweeter flavor than mature garlic cloves — and have become popular at farmers markets and in restaurants. They can be stir-fried, made into pesto, pickled, or grilled.

Softneck garlic does not produce scapes. This is not a disadvantage for most growers, but it is a genuine culinary bonus that hardneck growers enjoy.

Planting Guidelines

Both types are planted in fall, typically 4–6 weeks before the ground freezes, so roots can establish before winter. Per Penn State Extension:

• Planting depth: 2 inches (tip of clove) below soil surface
• Spacing: 6 inches within row, 12 inches between rows
• Orientation: pointed end up
• Mulch: 3–4 inches of straw over beds after planting to prevent frost heave and moderate soil temperature

In my Long Island zone 7a, this means planting in mid to late October. The target is roots establishing before the ground freezes (typically December in Long Island) but tops remaining below ground through winter.

Both types emerge in early spring and are harvested when the lower 1/3 of leaves have turned brown — typically late June to mid-July in zone 7a.

Storage Comparison

Per Clemson HGIC, the critical storage condition is low humidity. Garlic stored in high humidity develops mold on the outer skin layers and rots from the base. Mesh bags or open wooden boxes in a basement or cool pantry (50–60°F) are ideal. Do not refrigerate cured garlic: refrigerator humidity causes rapid mold development.

Curing After Harvest

Per Penn State Extension, both types require curing before storage:

1. Harvest when lower 1/3 of leaves are brown
2. Lay or hang in a dry, shaded, well-ventilated location (not in sun) for 3–4 weeks
3. After curing, trim roots and cut stalks to 1 inch above the bulb (hardneck) or leave stems intact for braiding (softneck)
4. Move to long-term storage

Curing allows outer skin layers to dry and form a protective barrier around the bulb. Uncured garlic stored immediately after harvest develops mold quickly.

Soil and Fertility Requirements

Per Cornell Cooperative Extension, garlic performs best in:

• Well-drained loamy soil (waterlogged soil causes basal plate rot)
• pH 6.0–7.0
• Moderate fertility; avoid excessive nitrogen that promotes leaf growth over bulb development
• No compaction — garlic bulbs need loose soil to expand properly

Compost at 2 inches per season is usually sufficient fertility. Per Penn State Extension, a side-dressing of nitrogen fertilizer (1 lb of actual N per 100 sq ft) in early spring when tops are 6 inches tall helps drive bulb development, but heavy nitrogen applications in late spring produce large tops and small bulbs.

Common Problems

Frequently Asked Questions

Can I plant garlic from the grocery store?

Per Penn State Extension, most grocery store garlic is softneck artichoke type and is often treated with growth inhibitors to prevent sprouting. It can be planted but may produce poorly compared to seed garlic from a reputable supplier. More importantly, it can carry viruses and fungi not present in tested seed stock. Purchase certified virus-free seed garlic for best results.

How many cloves does one plant produce?

Per Cornell Cooperative Extension, one garlic clove produces one bulb. Hardneck varieties with 4–8 cloves per bulb multiply by that factor; a single Porcelain clove planted in fall produces one bulb with 4–6 new cloves the following summer. Softneck artichoke types with 12–20 cloves per bulb multiply faster per planting unit.

Is hardneck garlic harder to grow?

Not harder — different. Per Clemson HGIC, hardneck garlic is actually more forgiving of northern cold climates than softneck and requires no special treatment beyond adequate mulching after fall planting. The disadvantage is shorter storage life, which matters only if you are growing for year-round home use rather than fresh culinary use.

What is elephant garlic?

Elephant garlic (Allium ampeloprasum) is not actually garlic — it is more closely related to leeks. Per NC State Extension, it produces very large but mild-flavored bulbs (2–4 inches diameter) and is a softneck type that overwinters in zones 5–9. The mild flavor appeals to some cooks; garlic enthusiasts generally prefer true garlic varieties for flavor intensity.
