Chives

Sun

Full sun to light shade; afternoon shade helps in hot climates.

Water

Keep evenly moist during active growth, watering when the soil surface begins to dry. Avoid waterlogged soil, especially in winter.

Soil

Fertile, well-drained soil that holds some moisture; slightly acidic to slightly alkaline conditions are suitable.

Height

1-1.5 ft (0.3-0.45 m), including flowers

Spread

0.5-1 ft (0.15-0.3 m) per clump

Flowers

Late spring to early summer; rounded heads of pale purple to pinkish-mauve flowers.

Foliage

Fine, upright, hollow green leaves with a mild onion scent when crushed; usually dies back in winter.

Growth

Moderate

Care needed

Low

• Water during dry spells to keep leaves tender; check pots more often than plants in the ground.
• Top-dress with compost in spring; feed container plants lightly during active growth.
• Apply a thin compost mulch around clumps, keeping it clear of the leaf bases.
• Divide crowded clumps every three or four years in spring or early autumn.
• Remove spent flower heads before seeds ripen if you do not want seedlings.

Pruning. Harvest established plants by cutting leaves about 1-2 in (2.5-5 cm) above the soil, leaving some growth to recover. Cut down tired foliage after flowering for a fresh flush, and remove dead leaves once the plant becomes dormant.

Early spring

Remove dead foliage, top-dress with compost and divide congested clumps as new growth starts.

Spring

Sow seeds or plant young clumps after preparing a weed-free, well-drained bed.

Late spring

Harvest leaves regularly and leave some flowers for bees or use them fresh in food.

Summer

Remove fading flower heads before seed forms; cut back coarse leaves and water to encourage regrowth.

Early autumn

Divide or transplant clumps while the soil is still warm and moist.

Winter

Keep dormant plants out of standing water and check that container drainage holes remain clear.

• Edge vegetable beds or herb paths with repeated clumps for a low, soft boundary.
• Plant beside parsley and thyme in a sunny kitchen garden, allowing enough space to water each according to its needs.
• Repeat through cottage borders with catmint and hardy geraniums for fine foliage and mauve early-season flowers.
• Grow in containers near the kitchen door for easy harvesting and a compact seasonal display.

Garden styles it suits: Cottage garden, Potager (kitchen garden), Herb parterre, Edible landscape, Pollinator garden and Small-space.

Plant it with: Parsley, Thyme, Strawberries, Lettuce, Catmint and Hardy geraniums.

Wildlife: The flowers supply nectar and pollen to bees and other visiting insects. Let some clumps flower rather than harvesting every leaf and flower stem.

• Rust: orange pustules appear on leaves, especially in damp, crowded growth. Remove affected foliage, improve spacing and avoid wetting the leaves when watering.
• Aphids: colonies can gather on soft growth. Wash them off with water and remove heavily infested leaves.
• Rot in wet soil: yellowing, collapsing growth can follow prolonged waterlogging. Improve drainage or move healthy divisions into fresh, free-draining soil.
• Dry, coarse or yellowing leaves: drought, flowering or congested roots can reduce leaf quality. Water deeply, cut back tired growth and divide crowded clumps.

All parts are toxic to cats, dogs and horses if eaten, including fresh or dried leaves, flowers and bulbs. Ingestion can damage red blood cells and cause serious anaemia; contact a veterinarian promptly if a pet or horse eats chives. Chives are not known to be toxic to people in normal culinary amounts, although large amounts may cause digestive upset.

• Garlic chives (Allium tuberosum)

  Has flat, strap-like leaves with a garlic scent and white, starry flowers in late summer, rather than hollow leaves and mauve spring flowers.

• Crow garlic (Allium vineale)

  Also has narrow, hollow leaves, but its taller flower stems often carry clusters of small bulbils instead of the dense, evenly flowered mauve heads of chives.

The species name schoenoprasum comes from Greek words meaning 'rush' and 'leek', referring to its slender, rush-like leaves.

Propagation. Divide established clumps in spring or early autumn and replant small groups of bulbs with their roots attached. Alternatively, sow seed shallowly in spring and keep the compost moist until seedlings establish; plants also self-seed if flower heads are left to ripen.
