Rak Tamachat Cilantro, Heirloom Seeds — The Thai Permaculture Heirloom With Huge 2-Inch Leaves and Milder Flavor

Rak Tamachat Cilantro (Coriandrum sativum) is a rare heirloom cultivar named for the Rak Tamachat Permaculture and Natural Building Education Center in Thailand. The standout feature: exceptionally large plants with huge leaves up to 2 inches wide — far larger than standard cilantro. The flavor is milder than other cultivars, making it approachable for those who find standard cilantro too intense. Rich in antioxidants, vitamins, and minerals with a long history of culinary and therapeutic use. 50–55 days to leaf harvest; 90–105 days for seed.

Growing Notes

Direct sow (recommended) spring through late summer. Sow 1–2 seeds per inch, ¼–½ inch deep. For leaf harvest, no need to thin — grows well sown thickly. For coriander seed production, thin to 2–4 inches apart. Succession sow every 2–3 weeks for continuous leaf harvest. Bolting is likely in midsummer heat — sow in part shade or time for spring/fall harvest. Germination in 7–10 days at 65–70°F.
