Comanche Leek is a refined, long-shanked F1 hybrid leek built for reliable harvests across a broad hardiness range of zones 3 through 11. Reaching maturity in approximately 105 days from transplants, this compact variety produces the refined white shanks that make leeks prized for elegant soups, stews, and grilled preparations. Its frost-hardy nature means you can push harvests deep into fall, and in milder climates, leave plants in the ground to harvest as winter needs dictate.

This leek's long, refined shanks develop with remarkable consistency, making it dependable for both home gardeners and small-scale growers who need uniform harvests. The compact growth habit combined with frost-hardiness gives you flexibility in timing and storage options, whether you're harvesting fresh or leaving plants to overwinter in the garden. Its heavy nutrient demands reward fertile soil with exceptional quality and mild, sweet flavor that shines in everything from creamy potato-leek soup to simple grilled preparations.
Comanche Leek excels in the kitchen as a foundational ingredient for soups and stews, where its mild, refined flavor builds depth without overpowering. Slice it into slivers for omelets, grill whole sections for a tender side dish, or add to braise dishes where the white shanks become meltingly soft. Fresh use in salads is also possible, particularly when harvested at the tender finger-size stage.

Sow seed in flats 10 to 12 weeks before your last spring frost date, placing seeds 1/4 inch apart and 1/4 inch deep. Maintain germination temperatures of 50 to 70°F. Thin seedlings to one plant per cell in plug flats, or thin densely sown flats to individual strength. If tops reach over 5 inches before transplant time, cut them back to 3 inches to encourage stocky growth.
Beginning in late spring when seedlings reach approximately 8 inches tall and pencil thickness, transplant into the garden 6 inches apart in rows spaced at least 12 inches apart. Dibble holes 6 inches deep and slide each transplant into the hole, leaving only 2 to 3 inches of leaves above soil surface; this buried portion will blanch into the refined white shank. Do not firm soil around the transplant; instead, allow irrigation or rain to gradually fill the dibble hole.
Direct sowing is possible; thin seedlings to the strongest plant when they reach 4 to 5 inches tall.
Harvest Comanche Leek anytime the white shank reaches 1/2 inch in diameter or larger for the best texture and flavor. You can harvest at finger size for milder, more tender leeks suited to fresh salads. Unlike onions, leek tops do not die back, so visual maturity cues differ; instead, gauge readiness by shank diameter and height. In areas where soil freezes, leeks can be harvested as needed until the ground becomes solid; in milder climates, they can remain in the garden all winter and be harvested throughout the season.
