Garlic Chive
Garlic chives (Allium tuberosum) are a perennial herb from the amaryllidaceae family that brings together the delicate onion flavor of chives with a subtle garlic undertone. Hardy in zones 3 through 9, these clump-forming plants grow 12 to 18 inches tall and mature into sturdy mounds of bright green, chive-like foliage topped with fragrant white star-shaped flowers in late summer and early fall. Ready to harvest in around 85 days, they thrive in full sun with moderate water and moderate maintenance, making them a low-effort addition to herb gardens, containers, or naturalized plantings. The edible stems, leaves, and flowers all bring fresh garlic-onion flavor to the kitchen, while their deer resistance, drought tolerance, and ability to attract pollinators round out their garden value.

These hardy perennials start slowly from seed but quickly establish into vigorous, self-sufficient plants that need little coaxing once established. The white flowers that crown them in late summer and early fall are not just ornamental; they're edible and add a delicate garlic bite to salads and other dishes. Garlic chives spread by self-seeding and underground rootstocks, which means a small initial planting can eventually colonize a larger area, so deadheading spent flowers before seed sets helps keep them in check if you prefer a tidy garden. Their gray-green leaves remain productive year-round in colder zones, and a simple shear back to 4 inches after flowering encourages tender new growth for continued harvests.
Harvest the bright green stems and leaves year-round to add fresh garlic-onion flavor to egg dishes, soups, stir-fries, and Asian cooking. The white flowers that emerge in late summer are also edible and bring a delicate garlic note to salads and other dishes. Unlike the bulbs of true garlic, the fibrous underground bulbs of garlic chives are not eaten; instead, it's the tender leafy stems that deliver all the culinary value. They work beautifully as a fresh herb in the kitchen much like regular chives, but with that distinctive garlic undertone that makes them especially useful in Asian recipes and fermented preparations like kimchi.
Sow seeds indoors 6 to 8 weeks before your average last frost date. Sow thinly in seed starting mix and cover with 1/4 inch of soil. Keep evenly moist as seedlings slowly emerge and provide good light. Gradually acclimate plants to outdoor conditions before transplanting.
Transplant seedlings outdoors when they are 2 to 3 inches tall, after hardening off. Plant clusters of 7 to 10 seedlings spaced 8 to 10 inches apart outdoors. Transplant 6 to 8 weeks before your average last frost date.
Sow seeds outdoors directly 4 to 6 weeks before your average last frost date, as soon as soil can be worked, or as late as 2 months before your first fall frost date. Soil temperature should be at least 45°F, ideally 60 to 70°F.
Begin harvesting garlic chive stems once plants are established, typically around 85 days from planting. Harvest the bright green leafy stems and leaves fresh for immediate kitchen use throughout the growing season. The white edible flowers can be picked as they emerge in late summer and early fall. Since these are perennials, you can take stems and leaves repeatedly without harming the plant; harvest from the outside of the clump and allow the center to continue growing.
After the white flowers finish blooming in late fall, shear the entire plant back to 4 inches to encourage regrowth of tender new leaves. This rejuvenation pruning keeps plants productive and maintains a neat appearance. Deadhead flowers before seed sets if you want to control unwanted self-seeding, as garlic chives spread readily by both seed and underground rootstocks.

“Garlic chives arrived in American seed catalogs through the hands of home gardeners who recognized their value in traditional cooking. At the Gardiner Library in Hudson Valley, New York, a regular patron named Insook brought in her homemade kimchi to share with library staff. That simple jar of preserved garlic chive stalks, appearing at first glance like chopped grass but tasting like one of the finest kimchis ever made, sparked enough interest that seed companies began actively growing and selling garlic chive seeds. What began as a cultural tradition shared in a public library became a small but meaningful moment in seed preservation and culinary plant commerce in North America.”
