Grow fragrant leaves and spice-rich seeds
Coriander/Cilantro Seeds encompass aromatic annual varieties prized for both lush foliage and spice-rich umbels. As a cool-season herb and long-standing herb garden staple, this crop delivers fresh cilantro leaves as well as the warming coriander seed spice. Botanically known as Coriandrum sativum (Coriander), it supports biodiversity; lacy umbel flowers act as a beneficial insect attractor and are valued by pollinating insects. Options within this category range from leaf-forward types to slow-bolt coriander lines aimed at extended cutting. Synonymous selections may appear as Cilantro herb seeds, Chinese parsley seeds, or Dhania seeds, reflecting culinary traditions where leaf coriander and seed are equally appreciated. In mixed borders the fine texture adds a soft, ornamental layer while providing culinary usefulness.
For dependable harvest windows, many gardeners favour bolt-resistant cilantro strains and succession sowing to maintain a steady supply of foliage. As a guide, direct sow after the last frost, and in mild climates autumn sowing may be possible for an early spring flush. In hotter spells, growth benefits from full sun with light shade during peak heat to reduce premature bolting. Compact selections also suit container herb gardening, keeping a steady source of fresh cilantro leaves close at hand. Whether grown for leafiness or for mature, aromatic seed, Coriander/Cilantro Seeds fit seamlessly into companion planting schemes, where airy canopies shelter young seedlings of other crops and the umbels invite predatory insects.
This category supports varied uses: harvest leaves and seeds from the same plants, cut baby foliage for cilantro microgreens, or allow umbels to mature for a fragrant seed crop. Container-suitable types perform well in pots and planters, while robust strains anchor herb beds and edible borders. The pollinator-friendly herb brings a long flowering display that sustains garden life and encourages natural balance. With options spanning slow-bolt and leaf-holding profiles, Coriander/Cilantro Seeds and complementary Coriandrum sativum seeds offer adaptable choices for kitchens and landscapes alike, from direct sow coriander in spring to late-season seed heads that dry into pantry-ready spice.
Coriandrum sativum (Coriander)
This range groups the wider herb collection and closely related categories, useful for planning a mixed kitchen garden around coriander. Links cover growth habit, speed, container suitability, and culinary companions such as basil, parsley, mint, and oregano. Use these links to compare options for succession sowing and to find organic choices that fit different growing approaches.
Coriandrum sativum (Coriander)
This aromatic annual is a cool-season herb that thrives in full sun, with light shade in heat. Sow directly after the last frost into well-drained, moderately fertile soil; in mild climates, autumn sowing may be possible. Keep the soil evenly moist, as drought speeds bolting. Use succession sowing every few weeks for a steady supply of fresh cilantro leaves. Thin seedlings to about 15β20 cm apart, and expect plants to reach roughly 30β60 cm tall. Coriander dislikes root disturbance, so direct sow where possible. For container herb gardening, use a deep pot with free drainage. Harvest leaves regularly, and allow a few plants to flower and set seed for umbels and future spice.
- Direct sow coriander to minimize root disturbance; transplant only very young seedlings if necessary.
- Use succession sowing; harvest early and provide partial shade in heat to slow bolting; choose slow-bolt strains.
- Container suitable: select a deep, well-drained pot and water consistently to avoid stress.
- Pollinator-friendly: white umbel flowers attract beneficial insects and support garden diversity.
- Edible: pick tender leaves for fresh flavor; later, dry mature seeds for coriander spice.
- Ornamental: ferny foliage and airy umbels add light texture to mixed plantings.
How do I grow cilantro from seed successfully?
For reliable results, direct sow Cilantro/Coriander seeds where they will grow, as this cool-season herb dislikes root disturbance. Choose well-drained, moderately fertile soil and aim for full sun, giving light shade during hot spells. Sow shallowly in prepared ground or containers, keep the surface evenly moist until emergence, then water regularly without waterlogging. Once seedlings show true leaves, thin to roughly 15β20 cm / 6β8 in between plants. Steady moisture and moderate fertility support leafy growth, while heat and drought encourage early flowering (bolting).
When should I plant coriander seeds after the last frost, and what about mild climates?
Sow coriander seeds in early spring once the soil is workable and the last frost has passed. In mild climates, autumn sowing may be possible, often giving a longer picking window before heat triggers bolting. To maintain continuous harvests of fresh cilantro leaves, practice succession sowing every 2β3 weeks through the cool parts of the season. As days lengthen and temperatures rise, expect faster bolting; plan earlier or later sowings to skirt peak heat.
How far apart should I space coriander plants, and how tall do they grow?
After germination, thin or transplant coriander to about 15β20 cm / 6β8 in between plants to reduce crowding, improve airflow, and encourage sturdier growth. Well-spaced plants are easier to harvest and slower to stress. Mature plants typically reach around 30β60 cm / 12β24 in in height. If sowing densely for baby leaves, you can harvest earlier and more frequently, but expect quicker bolting than with well-spaced, mature plants.
Can cilantro grow well in containers, and what setup works best?
Yesβcilantro is a dependable container herb. Use a pot with excellent drainage, roughly 20β25 cm / 8β10 in wide and at least as deep for a productive clump. Fill with a quality, well-drained potting mix and direct sow, then thin to a few robust plants. Provide full sun with light shade during heat, and water evenly since containers dry faster than garden soil. Avoid overfeeding; moderate fertility keeps leaves tender. Regular sowings in additional pots extend the harvest window.
What are tips to prevent cilantro bolting, and are bolt-resistant types helpful?
To slow bolting, keep plants growing steadily in cool conditions: sow early spring or in the cool shoulder seasons, provide light shade during hot weather, and maintain consistent moisture. Mulch lightly to keep roots cool, avoid crowding, and harvest frequently to encourage new leaves. Choosing βslow-boltβ or βbolt-resistantβ cilantro strains can add extra days of leafy growth, though no variety halts bolting once heat and long days dominate. Succession sowing remains the most reliable strategy for continuous supply.
Are coriander flowers good for pollinators, and how do I harvest the seeds for spice?
Corianderβs delicate umbel flowers are highly attractive to beneficial insects and pollinators, making it a useful companion in herb and vegetable beds. Allowing a few plants to bloom supports these visitors and may lead to gentle self-seeding. For the coriander seed spice, wait until umbels turn tan and seeds are straw-brown. Cut stems, hang or place in a breathable bag to finish drying, then gently rub or shake to free the seeds. Cure thoroughly in a dry spot before storing.

Grow fragrant leaves and spice-rich seeds
Coriander (cilantro) offers leafy freshness and aromatic seeds. Sow after last frost once soil warms; in mild climates autumn sowing may be possible. Choose well-drained soil, sow 6β10 mm deep, spacing 5β8 cm for leaf harvest or wider for seed production. Keep evenly moist; stress encourages bolting. Full sun to light shade, especially in heat; succession sow every few weeks for steady leaves. Germination typically 7β21 days; lightly crush whole seeds (schizocarps) to speed uptake. For leaves, harvest young growth regularly; for seeds, allow umbels to brown on the plant, then cut and dry before threshing. Taller, slower-bolting strains suit warm periods, while compact types fit containers. Avoid rich nitrogen just before seed set to enhance flavor. Coriander attracts pollinators and can accompany vegetables that appreciate natural pest support. Store dried seed in airtight containers. Related options appear under Herbs Seeds.
