The herb commonly known in the United States as cilantro, and its seeds as coriander, both originate from the same plant, Coriandrum sativum. This species is an annual herb belonging to the parsley family (Apiaceae). While the fresh leaves, or cilantro, are widely used in Latin American and Asian cuisines, the dried seeds, or coriander, serve as a warming spice in Middle Eastern and Indian dishes.
The Plant’s True Origin Point
Coriandrum sativum naturally evolved in the Mediterranean Basin, extending eastward into Southwest Asia and covering parts of North Africa. This wide geographical range makes it challenging for botanists to pinpoint a single location for the herb’s domestication, but the consensus points to this general region.
Ancient evidence for the plant has been found in locations like the Nahal Hemar Cave in modern-day Israel, dating back as far as the 6th millennium BC. This evidence suggests that the plant was utilized in the Levant and surrounding areas long before its widespread cultivation across the rest of Europe and Asia. Its genetic birthplace is tied to the relatively moderate, subtropical climates of the Eastern Mediterranean and Western Asia.
Environmental Requirements for Natural Growth
The natural growth requirements of cilantro reflect its origins in a cool, temperate climate, classifying it as a cool-season annual. The plant thrives best in full sun to light afternoon shade, but it cannot tolerate the extreme heat of midsummer.
Temperatures that consistently rise above 75°F (24°C) trigger a process called bolting, where the plant prematurely sends up a flower stalk and focuses on setting seed. This tendency to bolt quickly means the herb naturally flourishes during the spring and fall in temperate zones, mirroring the moderate conditions of the Mediterranean spring.
In terms of soil, Coriandrum sativum is not demanding, preferring average, well-drained loams rather than overly rich or heavily fertilized ground. Good drainage is necessary to prevent root rot, and once established, the plant requires only moderate moisture.
Historical Global Distribution
The spread of Coriandrum sativum from its native Mediterranean and Southwest Asian range was primarily driven by ancient human migration and trade routes. Ancient Egyptian civilizations cultivated the herb, and seeds were placed in the tombs of pharaohs, including Tutankhamun, confirming its early status as a prized commodity.
The Greeks and Romans later embraced the herb, with Roman gastronome Apicius including coriander in one of the world’s first known cookbooks. As the Roman Empire expanded, they introduced the plant across Europe, establishing it far from its initial habitat.
Much later, during the Age of Discovery in the 16th century, European explorers and colonists became the agents of its final global dispersal. Spanish explorers introduced the plant to the Americas, where it quickly became an integral part of Latin American cuisine.
