Meet Siberian Chive
A robust chive variety with thicker, coarser hollow leaves and a stronger onion flavor than common chives. Siberian chives are extremely cold-hardy, surviving temperatures well below minus 40 degrees. They produce large pink-purple flower heads that are especially attractive to pollinators in early summer.
When to plant Siberian Chive
Sow Siberian chive seeds indoors 8 to 10 weeks before the last frost. Press seeds onto moist seed-starting mix and cover lightly. Germination takes 7 to 14 days at 65 to 70 degrees. Grow in bright light. Thin or transplant seedlings in clusters of 10 to 15 for faster establishment. Harden off and plant outdoors after the last frost. Direct sowing in spring is also successful. For quickest results, purchase or divide established clumps.

Used once to set your season · never sharedHow to grow Siberian Chive
Siberian chives are a particularly robust variety of common chives with thicker, coarser hollow leaves and a stronger onion flavor. They are among the hardiest culinary herbs available, surviving temperatures well below minus 40 degrees Fahrenheit. Plant in full sun with well-drained soil with a pH of 6.0 to 7.0. Space clumps 8 to 12 inches apart.
Start seeds indoors 8 to 10 weeks before the last frost or direct sow in spring. Seeds germinate in 7 to 14 days at 65 to 70 degrees. Transplant or thin to 8-inch spacing. Siberian chives can also be propagated by dividing established clumps in spring or fall, which is the fastest way to establish productive plantings.
Harvest regularly by cutting leaves to 2 inches above the ground, which encourages continuous fresh growth. Divide clumps every 3 to 4 years when the center becomes woody and less productive. The large pink-purple flower heads are ornamental, edible, and excellent for pollinators. Remove spent flowers to prevent self-sowing or allow some to naturalize for a continuous supply.

Siberian Chive's best neighbours
Chives are beneficial companions for many garden plants, as their strong allium scent repels aphids and other pests. Plant near roses to deter black spot and aphids. They are traditional companions for carrots, helping repel carrot rust fly. Avoid planting near peas and beans, as alliums may inhibit their growth. Chives make excellent edging plants for herb and vegetable gardens.
It flags clashes before you plant, not after
Every plant you place is checked against its neighbours in real time. Good matches glow green; conflicts get flagged on the spot — so a season-wrecking mistake never makes it into the ground.
Feed it well
Siberian chives grow well in average to rich, well-drained soil with a pH of 6.0 to 7.0. They tolerate a range of soil types from sandy loam to clay. Apply balanced organic fertilizer in early spring when new growth emerges and again after the first heavy harvest. Top-dress with compost annually to maintain soil fertility. Mulch lightly to conserve moisture. Container-grown chives benefit from monthly feeding with liquid fertilizer during the growing season.

From seed to harvest, stage by stage
Seed Germination
Siberian chive seeds are small, dark, and angular. They germinate in cool to moderate soil temperatures, often emerging in 10-18 days. The first visible growth is a single thin, hollow tube that curves as it pushes through the soil surface. Seeds can germinate at soil temperatures as low as 7°C (45°F), though the optimal range is 15-20°C (60-68°F), reflecting the cultivar's adaptation to short northern growing seasons.
Seedling Development
Additional hollow, cylindrical leaves emerge from the central growing point, each slightly thicker than the last. Growth appears slow above ground as the plant prioritizes developing a dense, fibrous root system capable of surviving harsh winters. By the end of this stage, seedlings typically have 4-8 thin leaves and stand 8-12 cm tall.
Vegetative Growth
Plants enter a period of accelerating leaf production. The characteristic thick, hollow, cylindrical leaves of the Siberian cultivar become evident — noticeably stouter and more upright than those of common chives. Clumps thicken as the plant tillers from its base, producing multiple leaf shoots from expanding bulblets. A healthy plant at this stage will have 15-30 leaves reaching 25-35 cm in height with a distinct mild onion aroma.
Flowering
Sturdy flower scapes rise above the foliage, each topped by a spherical cluster of lavender-purple florets. Siberian chives produce larger, more intensely colored flower heads than standard common chives, often 3-4 cm in diameter. The blooms are highly attractive to pollinators and last 2-3 weeks. Leaf production slows during flowering as the plant redirects energy to reproduction.
Harvest Maturity and Regrowth
After flowering, plants produce a vigorous second flush of tender new leaves. This post-bloom regrowth often yields the most flavorful leaves of the season. Established clumps can be harvested every 3-4 weeks through summer and into early autumn. Second-year and older plants are substantially more productive than first-year seedlings.
Dormancy and Overwintering
After hard frost, foliage yellows and collapses to the ground. The dense network of small bulblets and fibrous roots enters dormancy beneath the soil surface. Siberian chives are among the hardiest of all alliums, with root systems surviving sustained soil temperatures as low as -40°C (-40°F). Each year the clump expands outward as new bulblet divisions form, and established plants emerge progressively earlier in spring.
Sow seeds 6mm deep in moist seed-starting mix. Unlike many herbs, Siberian chive seeds do not require heat mats — cool room temperatures of 15-18°C (60-65°F) are ideal. Keep the surface evenly moist with a misting bottle and cover trays loosely with a humidity dome.

You are hereFlowers are in full bloom. Deadhead spent blossoms before seed pods form to prevent aggressive self-seeding. After flowering, feed generously to promote a strong second flush of tender new leaves. Monitor for aphids on flower stalks.
Harvesting Siberian Chive
Cut Siberian chive leaves when they are at least 6 inches tall, snipping to 2 inches above the base to encourage regrowth. Use sharp scissors or kitchen shears for clean cuts. Harvest regularly from the outside of the clump, allowing center growth to continue. The flowers are also edible and can be separated into individual florets for garnishing salads and soups. Flavor is strongest in spring and fall; summer heat can make the leaves tougher.

Storage & Preservation
Fresh chives store in the refrigerator for up to a week in a damp paper towel inside a sealed container. For long-term storage, chop finely and freeze in ice cube trays with a small amount of water or oil. Frozen chives retain good flavor for 6 months in cooking. Drying is less successful, as much of the delicate onion flavor is lost. Chive blossom vinegar, made by steeping purple flower heads in white wine vinegar for 2 weeks, produces a beautiful pink vinegar with mild onion flavor.
What goes wrong — and the fix
Onion Thrips
PestSilvery streaks and stippling on leaves. Tiny slender insects visible on close inspection. Severe infestations cause leaf distortion and reduced growth.
Rust
DiseaseOrange-brown pustules on leaves. Affected leaves yellow and die. Most common in wet, humid conditions with poor air circulation.
Troubleshooting Common Problems
The main issue with Siberian chives is their vigorous spreading through self-sowing and clump expansion. Deadhead flowers before seeds mature to control spread, or plant in contained areas. Clumps become congested and less productive after 3 to 4 years; divide regularly. Rust disease can disfigure foliage in wet years. The stronger onion flavor may be overpowering for those accustomed to common chives; use sparingly until familiar with the intensity.
Growing Tips
- Choose a location with full sun for the most productive plants, though Siberian chives tolerate partial shade (4-5 hours of direct sun) better than most alliums. In hot climates (zones 7-9), afternoon shade actually improves leaf quality and prevents premature tip browning.
- Plant in clusters of 4-6 seedlings spaced 25-30 cm apart rather than as isolated individuals. Clustering establishes a substantial, harvestable clump within the first season and creates a more attractive garden display.
- Siberian chives thrive in almost any well-drained soil but produce the thickest, most flavorful leaves in moderately rich ground amended with compost. Avoid heavy clay that stays waterlogged — if drainage is poor, plant in raised beds or mounded rows.
- Harvest by cutting the entire clump to 3-5 cm above the soil surface with sharp scissors or garden shears. Never pull individual leaves, as this can uproot shallow bulblets and damage the growing crown.
- Water deeply and apply nitrogen-rich liquid fertilizer immediately after every harvest. This post-harvest care is the single most important factor in accelerating regrowth and maintaining leaf thickness throughout the season.
- Deadhead spent flowers before seed pods mature to prevent vigorous self-seeding. Siberian chives are prolific self-sowers and can colonize garden paths and beds if flowers are left to drop seed unchecked.
- Divide overcrowded clumps every 3-4 years in early spring just as new growth emerges. Lift the entire clump, separate into sections of 8-10 bulblets, and replant at the original depth. This reinvigorates declining clumps and prevents hollow dead centers.
- Freeze surplus chives for winter use by snipping leaves into 5mm rings and spreading them in a single layer on a parchment-lined baking sheet. Once frozen solid, transfer to airtight bags. Frozen chives retain their color and flavor far better than dried ones.
- Use Siberian chives as a companion plant throughout the garden — their sulfurous compounds help deter aphids, carrot rust fly, Japanese beetles, and some fungal diseases. Plant them as borders around roses, near fruit trees, or between rows of carrots and brassicas.
- For the earliest possible spring harvest, cover established clumps with a small cold frame or clear plastic cloche in late winter. The trapped warmth can push new growth 2-3 weeks ahead of uncovered plants, providing fresh chives while the rest of the garden is still dormant.

Where Siberian Chive comes from
Siberian chives (Allium schoenoprasum 'Siberian') are a robust cultivar selected from wild populations of common chives native to the vast grasslands, river valleys, and mountain meadows of Siberia and northern Central Asia. The species Allium schoenoprasum has one of the widest natural distributions of any allium, spanning from the Atlantic coast of Europe across the entire Eurasian landmass to Japan, and across the Bering region into North America. The Siberian ecotype evolved in some of the harshest inhabited landscapes on Earth, developing exceptional cold hardiness, thicker leaves, and vigorous growth during the brief northern growing season.
Chives have been gathered from the wild and cultivated across Europe and Asia for thousands of years. The earliest written references appear in Chinese texts dating to roughly 3000 BCE, while European records of deliberate cultivation begin in the Middle Ages, when chives were a staple of monastic herb gardens. Monks valued them for culinary, medicinal, and pest-repelling properties. The name 'chive' derives from the Latin cepa (onion) through the Old French cive. Marco Polo reportedly noted the extensive use of wild chives by nomadic peoples during his travels across Central Asia in the late 13th century.
The deliberate selection of the Siberian cultivar reflects a modern interest in identifying and propagating the most cold-tolerant, vigorous, and flavorful strains for northern gardeners. Seed collected from wild Siberian populations was trialed by Scandinavian and Canadian plant breeders in the 20th century, leading to named selections prized for their ability to thrive where winters regularly reach -40°C and growing seasons last barely four months. Today, Siberian chives are especially popular among gardeners in Canada, Alaska, Scandinavia, and northern Russia, where they are often the first herb to emerge in spring and the last to succumb to autumn frost.
