Description
Plump and fresh Xiangfei large-leaf coriander seeds maintain reliable germination activity. Coriander (cilantro) is one of the most widely used aromatic culinary herbs worldwide, prized for its distinctive fresh fragrance in soups, salads, stir-fries and seasoning dishes. This Xiangfei large-leaf variety produces broad, lush, dark-green leaves with thick tender stems and concentrated classic coriander aroma. It features vigorous growth, good bolting resistance and stable yield performance under suitable cool conditions. Both fresh leaves and mature seeds are edible and widely used in cooking. The seed pack is suitable for backyard garden beds, balcony containers, raised planters and small-scale commercial field production. When designing your culinary herb garden, you can pair it with 40gram Australian Four-Season Coriander Seeds to compare leaf-size and growth performance between varieties. Coriander prefers full-sun or light-partial-shade locations and loose, fertile, well-drained loamy soil. Heavy waterlogged clay soil must be completely avoided to prevent root rot and seedling death. Daily management focuses on consistent moisture, timely leaf harvest before bolting, and weed control. It is a beginner-friendly, fast-growing leafy herb suitable for successive sowing across cool seasons. For spice-herb growers wanting to diversify, 50gram organic caraway seeds offer an excellent complementary aromatic herb option.
Planting Instructions
Soil Preparation
Choose a sunny or lightly shaded planting plot. Mix fertile garden topsoil with decomposed organic fertilizer and fine river sand to create loose, breathable growing substrate. For low-lying or high-rainfall areas, build slightly raised seedbeds to ensure rapid rainwater drainage and eliminate standing water. Compacted, poor-air-permeability clay soil is not suitable for coriander cultivation.
Seed Pre-treatment
Coriander seeds have a hard round outer husk. Gently crush whole seeds to split them into two halves before sowing. Soak split seeds in clean cool water for 10–14 hours to soften the seed coat and significantly improve germination rate. Discard any floating empty or damaged seeds. No low-temperature cold stratification is required.
Sowing Method
Sow in spring, autumn or cool periods of summer. Broadcast seeds evenly or drill in shallow rows, then cover with a 0.5–1 cm thin layer of fine soil. Keep 10–15 cm spacing between plants and 25–30 cm between rows. Thin out weak seedlings after 2–3 true leaves emerge, leaving vigorous plants with adequate growing space.
Germination Condition
The optimal germination temperature is 15–22°C. Seedlings will emerge within 10–21 days under proper soil moisture and temperature conditions. Keep soil consistently slightly moist, avoid water accumulation. Sustained high temperature above 28°C will suppress germination and trigger premature bolting.
Daily Maintenance
Water moderately to keep soil moist but not waterlogged. Remove surrounding weeds regularly to reduce nutrient competition. Apply diluted nitrogen-rich fertilizer once or twice during the active leaf-growing stage to promote lush foliage. Harvest young tender outer leaves 30–45 days after sowing for repeated cut-and-come-again harvest. If you wish to collect coriander spice seeds, leave several plants to bolt, flower and ripen fully.

FAQ
Q1: Why should coriander seeds be crushed before sowing?
A1: Coriander has a hard round seed husk; splitting the seeds allows water to penetrate and greatly increases germination rate and speed.
Q2: Can Xiangfei large-leaf coriander grow in balcony pots?
A2: Yes, it grows well in deep containers with drainage holes, placed in a sunny or lightly shaded location.
Q3: How soon can I start harvesting fresh coriander leaves?
A3: You can begin picking tender outer leaves approximately 30–45 days after sowing for continuous harvest.
Q4: What is the main advantage of large-leaf coriander over ordinary types?
A4: It produces broader, thicker leaves with higher leaf yield per plant and concentrated aromatic flavor.
Q5: What causes coriander to bolt and turn bitter?
A5: Persistent high temperature, insufficient water and long daylight hours trigger early bolting, after which leaves become bitter and less palatable.
