Coriandrum sativum. Santo is a popular home garden and commercial variety for all-season sowing, Direct sow short rows of Santo every other week from spring to late summer for a continuous harvest. The mature seeds, better known as coriander, are easy to harvest, and used in many dishes - notably curry powder blends. Keep an eye on your cilantro crop as it is fast-growing. As soon as a central stem appears and the uppermost leaves become frilly, flowering is imminent.
If growing for seeds, simply allow the plants to flower. Cilantro flowers are highly attractive to beneficial insects like Syrphid flies, lacewings, and lady beetles. Be warned that if the seeds are not harvested when they are mature, you will have volunteer cilantro plants for years to come.
Cilantro will grow somewhat leggy, but productively in partial shade, and it is quite tolerant of cool temperatures. With the protection of a cloche greenhouse, cilantro will continue growing all winter.
West Coast Seeds Santo Cilantro Seeds, Per Package
Starting
Sow 2cm (1″) deep in short rows. Thin seedlings to stand 5-10cm (2-4″) apart if harvesting leaves. If growing for seed, allow 23cm (9″) between plants.
Timing
Direct sow from just after the last frost date to late spring. Direct sow in the fall under cover for a winter crop. Optimal soil temperature for germination: 15°C (60°F). Seeds should sprout in 5-10 days.
Harvest
Pick young leaves once they have reached about 10cm (4″) in height. The flavour, though intense when fresh, diminishes quickly when dried or cooked, so always add cilantro just before serving. Try freezing it in ice cube trays with water. The stems and roots are also full of flavour. Harvest the seeds by sticking 6 or 8 seed heads in a paper bag and hanging it up somewhere airy, away from direct sunlight. The bag will catch the seeds as they ripen and fall out.
