Care information

Proper storage and handling can help maintain seed quality and germination performance. Keep seeds sealed, dry and protected from heat, moisture and direct sunlight.

Storage: For best long-term storage, keep seeds refrigerated in a clean, airtight container or securely sealed packaging. A refrigerator at approximately 4°C provides a cool, stable environment that can help maintain seed viability. If refrigeration is not practical, store seeds in the coolest available dry, dark and temperature-stable location.

Moisture: Keep seeds dry at all times during storage. Excess moisture or humidity can reduce seed quality and encourage premature germination, mould or deterioration. Always reseal opened packaging promptly.

Removing Seeds from Refrigeration: Keep refrigerated seeds sealed while they return to room temperature before opening the package or container. This helps prevent condensation from forming on cold seeds and introducing unwanted moisture.

Temperature: Avoid repeated temperature changes and do not store seeds near ovens, heaters, windows, vehicles, sheds or other areas exposed to excessive or fluctuating heat.

Handling: Use clean, dry utensils when removing seed from larger packs and return the remaining seed to refrigerated storage promptly after use.

Before Sowing or Sprouting: Inspect seeds before use and discard any showing signs of moisture damage, mould, unusual odour or deterioration. When growing edible sprouts or microgreens, use clean equipment and drinking-quality water.

Best Quality: Use seed while fresh and follow any product-specific storage, germination and growing information provided in the Specifications, growing instructions or product packaging.

Regional and remote destinations may take longer. Orders containing seed sent to Western Australia, Tasmania or other biosecurity-controlled destinations may also require additional processing or inspection.

Delivery estimates are provided as a guide only and can be affected by carrier delays, weather, peak periods and biosecurity requirements.

Tracking

All shipped orders include tracking. Once your order has been dispatched, you will receive an email with your tracking information so you can follow its progress.

Authority to Leave

Depending on the carrier and delivery service, your parcel may be left in a safe location if no one is available to receive it. You can provide delivery instructions during checkout where supported by the carrier; however, specific delivery requests cannot always be guaranteed.

Local Pickup – Riverstone, NSW

Local pickup can be selected at checkout when available. Please allow approximately 2–3 business days for your order to be prepared.

Wait until we contact you to confirm that your order is ready and arrange a suitable collection time.

Please do not attend the warehouse without an appointment. All pickups are strictly by prior arrangement.

Seed Biosecurity – WA & Tasmania

Seeds and other plant material may be subject to state biosecurity restrictions.

Western Australia has specific entry requirements for seed, and seed consignments may be inspected by Quarantine WA. Tasmania also regulates the importation of viable seed, with additional requirements applying to certain species and consignments.

Requirements vary by seed species, quantity and destination and may change over time. Customers in Western Australia, Tasmania and other biosecurity-controlled areas should check current state requirements before ordering.

Where an order contains seed that cannot meet applicable biosecurity requirements, we may need to contact you before dispatch or remove affected products from the order.

Coriander Herb Seeds

Coriander Herb Seeds for growing fresh, aromatic leaves, stems, roots and culinary seeds. A versatile cool-season annual for curries, salsas, salads and Asian-inspired cooking, suitable for garden beds, raised beds and containers.

Description

Coriander Herb Seeds for Fresh Leaves & Culinary Seed

Coriander Herb Seeds grow into aromatic annual herbs valued for their fresh green leaves, tender stems, roots and mature dried seeds. Also known as cilantro when referring to the fresh foliage, coriander is widely used across Asian, Indian, Middle Eastern, Mexican and Latin American cooking.

The fresh leaves have a distinctive citrusy, aromatic flavour that works particularly well in curries, salsas, salads, soups, noodles, marinades and rice dishes. If plants are allowed to flower and set seed, mature coriander seeds develop a warmer, fragrant flavour suited to spice blends, curries, pickling and cooking.

Best Grown Through the Cooler Months

Coriander prefers cool to mild growing conditions and can bolt quickly during hot, dry weather. For the best leafy harvests, sow from autumn through spring in many Australian climates and keep the soil consistently moist.

Direct sowing into the final garden bed, raised bed or container is generally preferable because coriander dislikes unnecessary root disturbance. Under suitable conditions, germination usually occurs in approximately 7–14 days.

Fresh Coriander from Garden Beds or Pots

Grow coriander in fertile, moist but freely draining soil in full sun to partial shade. Allow approximately 15–20cm between established plants where growing for larger leafy plants.

Begin light harvesting once plants are well established, generally from around 35–45 days after sowing. Pick fresh outer leaves and stems as required while leaving enough central growth for the plant to continue developing.

Succession Sow for a Longer Harvest

Coriander is naturally a relatively short-lived leafy herb, particularly as temperatures rise. Rather than relying on a single planting, sow smaller batches every 2–3 weeks during suitable conditions to maintain a more continuous supply of fresh leaves.

Grow Coriander for Culinary Seed

If you want coriander seed for cooking, allow selected plants to flower naturally. Leave the developing seed heads on the plant until they become dry and brown, then harvest and finish drying them before storage.

This gives one crop two distinct culinary uses: fresh aromatic foliage early in the season and mature coriander seed later in the plant's life cycle.

How to Grow Coriander Herbs

Coriander is a cool-season annual herb grown for fresh leaves, stems, roots and mature culinary seed. Direct sowing is generally preferable because established coriander plants dislike unnecessary root disturbance.

Quick Start

  • Sowing season: Autumn to spring
  • Sowing method: Direct sow preferred
  • Sowing depth: approximately 6mm
  • Germination: 7–14 days
  • Germination temperature: approximately 18–21°C
  • Plant spacing: 15–20cm
  • Position: Full sun to partial shade
  • Mature height: approximately 40–60cm
  • First useful leaf harvest: approximately 35–45 days
  • Succession sowing: every 2–3 weeks

When to Sow

For much of Australia, coriander is best sown from:

Autumn through spring

General guidance:

  • Cool climates: spring and autumn
  • Temperate climates: autumn, winter and spring
  • Subtropical climates: autumn through spring
  • Tropical climates: favour the cooler, drier months
  • Hot and arid climates: favour autumn and winter

Hot, dry conditions can cause coriander to flower rapidly, shortening the leafy harvest period.

Sowing

Direct sowing is recommended.

  1. Prepare loose, fertile, well-drained soil.
  2. Sow approximately 6mm deep.
  3. Cover lightly and firm the soil gently.
  4. Water thoroughly using a gentle flow.
  5. Keep the soil consistently moist during germination.
  6. Thin seedlings once they are established.

Coriander can be raised in cells or pots if necessary, but direct sowing avoids unnecessary root disturbance.

Germination

Expect germination in approximately:

7–14 days

Aim for a soil temperature of around:

18–21°C

Maintain steady moisture during germination without leaving the soil waterlogged.

Position & Spacing

Grow in:

Full sun to partial shade

Allow approximately:

15–20cm between established plants

If growing in rows, allow around 20–30cm between rows.

During warmer weather, some afternoon shade can help reduce heat stress and extend leafy growth.

Watering

Keep the soil consistently moist but well drained.

Water deeply enough to moisten the root zone, then allow excess water to drain.

Avoid:

  • repeatedly allowing plants to wilt;
  • permanently saturated soil; and
  • shallow, irregular watering during hot weather.

Container-grown coriander may need more frequent watering because pots dry faster than garden beds.

Feeding

Coriander grown for leaves performs best in reasonably fertile soil.

Before sowing, incorporate mature compost or another suitable soil amendment where required.

Avoid excessive fertiliser, particularly once plants begin moving towards flowering.

Harvesting Leaves

Begin light harvesting once plants are well established, usually from approximately:

35–45 days after sowing

Pick healthy outer leaves and stems while leaving the central growing point intact.

Regular light harvesting allows the plant to continue producing foliage until flowering accelerates.

Preventing Early Bolting

Coriander naturally flowers as temperatures rise.

To extend leafy production:

  • grow during cooler seasons;
  • maintain consistent moisture;
  • avoid unnecessary root disturbance;
  • provide some afternoon shade during warmer weather; and
  • succession sow rather than relying on one planting.

Succession Sowing

For a more continuous supply of fresh coriander, sow a new small batch approximately every:

2–3 weeks

during suitable conditions.

This is generally more reliable than trying to keep one coriander planting leafy indefinitely.

Growing Coriander in Pots

Coriander grows well in containers.

Choose a pot at least approximately:

20cm deep

with:

  • good drainage holes;
  • quality potting mix;
  • full sun to partial shade; and
  • regular watering.

Sow directly into the final pot where practical.

Harvesting Coriander Seed

To produce culinary coriander seed:

  1. Allow selected plants to flower.
  2. Leave the flower heads in place while the seeds develop.
  3. Wait until the seed heads become dry and brown.
  4. Cut the stems and place the heads in a paper bag or clean container.
  5. Allow them to finish drying.
  6. Rub or shake the dried seeds free.
  7. Store only once fully dry.

Harvest & Storage

Fresh coriander leaves are best used soon after picking.

Keep freshly harvested leaves cool and protected from dehydration.

For dried coriander seed, store fully dried seed in an airtight container away from heat, moisture and direct sunlight.

Seed Storage

Store unused sowing seed sealed in a cool, dry and dark place away from heat, moisture and direct sunlight.
