Leek Seeds

Musselburg Giant Leek (Allium ampeloprasum var. porrum) is a classic Scottish heirloom renowned for producing enormous, thick white stems with outstanding winter hardiness. Originally developed near Musselburgh, Scotland during the 1800s, this time-tested variety has become one of the world's most respected exhibition and culinary leeks. Its mild, sweet onion flavor, vigorous growth, and ability to withstand freezing temperatures make it a favorite among home gardeners and market growers alike. Whether harvested young for tender baby leeks or grown to impressive exhibition size, Musselburg Giant consistently delivers exceptional quality.

Introduction

Leeks have been cultivated for thousands of years and remain one of the finest cool-season vegetables. Musselburg Giant is especially valued for its long, thick, snow-white shanks and handsome blue-green foliage. Unlike onions, leeks produce a delicate, sweet flavor without overwhelming pungency, making them an indispensable ingredient in soups, stews, casseroles, and gourmet dishes. This variety grows vigorously through cool weather and often improves in flavor after exposure to frost.

Flavor Profile

Musselburg Giant offers a rich yet delicate onion flavor that is noticeably sweeter and milder than common bulb onions. Cooking further enhances its natural sweetness, producing a smooth, buttery flavor that blends beautifully into soups, sauces, and roasted vegetable dishes. The tender white stems are especially prized, while the darker green leaves provide excellent flavor for homemade stocks and broths.

Growing Information

Leeks thrive in cool weather and fertile, moisture-retentive soil rich in organic matter. Start seeds indoors 8 to 10 weeks before the last spring frost or sow directly outdoors in cool climates. As plants grow, gradually mound soil around the stems or use deep planting methods to blanch the shanks, producing the long white stems prized by gardeners and cooks.

• Botanical Name: Allium ampeloprasum var. porrum
• Plant Type: Hardy biennial grown as an annual
• Days to Maturity: 110–130 days
• Plant Height: 24–36 inches
• Stem Diameter: Up to 3 inches under ideal conditions
• Sun Requirements: Full sun
• Soil: Rich, fertile, consistently moist, well-drained soil
• Spacing: 6 inches between plants

Regular watering and fertile soil encourage rapid growth and thick stems. Blanching by hilling soil around the stems creates the longest, most tender white shanks.

Harvest & Storage

Harvest whenever stems reach usable size by loosening the soil and gently lifting the plants. Musselburg Giant is famous for remaining in excellent condition even after repeated frosts and may be harvested throughout much of the winter in many regions. Fresh leeks store for several weeks under refrigeration, while plants left in the garden often remain harvestable until spring where winters are not excessively severe.

King Richard Leek (Allium ampeloprasum var. porrum) is an outstanding early-maturing leek prized for producing long, thick white stems with a wonderfully mild, sweet onion flavor.
