Hardneck Garlic
Allium sativum var. ophioscorodon
Hardneck garlic is the prairie gardener's garlic of choice: tougher than softneck varieties, fully winter-hardy across Alberta when planted properly in fall, and the only garlic type that produces edible flowering stalks called scapes. Scapes appear in late June and early July as curling, jade-coloured stems with a tight bud at the tip. Cutting them off (and eating them, blended into pesto, butter, or stir fries) redirects the plant's energy back into the underground bulb, producing larger heads at harvest in late July through mid August. Hardneck varieties have a strong, complex flavour and store for 4 to 8 months in a cool dry place (shorter than softnecks, but the flavour trade-off is worth it). Reliable hardneck varieties for Edmonton include the porcelain types 'Music', 'German White', and 'Romanian Red' (large cloves, strong flavour) and the purple-stripe types 'Chesnok Red' and 'Persian Star' (milder, marbled wrappers). Plant cloves in October before the ground freezes, mulch heavily with straw or chopped leaves, and the first green shoots emerge with the crocuses in April.
Quick Facts
Distribution
Garden vegetable. Hardneck varieties hardy throughout Alberta when fall-planted (Zone 2 with mulch, Zone 3 reliably).
Light
Full sun. Garlic shaded by taller crops sizes down dramatically.
Bloom Time
Late June through early July (the scape is the flowering stem; remove it for larger bulbs)
Soil
Rich, well-drained loam with high organic content. Edmonton's Black Chernozem grows excellent garlic when amended with compost. pH 6.0 to 7.5.
Water
Moderate. Consistent moisture from spring emergence through mid-July, then taper off in the final two to three weeks before harvest to firm up the wrappers and improve storage life.
Growing & Cultivation
Best Planting Time
October (typically October 1 to 20 in Edmonton). Plant 2 to 3 weeks before the ground freezes so cloves can root without sending up green shoots. Spring planting is possible but produces noticeably smaller bulbs.
Propagation
Plant individual cloves, pointed end up, 5 cm deep and 15 cm apart. Save your largest cloves from this year's harvest for next year's seed. After 2 to 3 generations of selection, you will have a strain adapted to your specific yard.
Pruning / Splitting
Cut scapes when they form a single curl (typically late June). Use them in cooking; they are one of the season's first kitchen treats. Letting scapes mature into seed heads reduces bulb size by 25 to 30 percent.
Seed Collection
Garlic does not produce true seed under normal conditions. Propagate by saving the largest cloves from each harvest to plant the following October.
Spacing
15 cm apart in rows 20 to 25 cm apart. Bed planting at 15 cm grid spacing works equally well.
