What Exactly Is a Sesame Plant?
The sesame plant (Sesamum indicum) is an annual flowering plant that produces pods filled with edible seeds—those tiny white, black, or golden nuggets you see on bread, in tahini, or popping up in your favorite Asian stir-fry.

But here’s the kicker: unlike most plants, sesame has a unique trait—it’s naturally dehiscent. That means when the pods ripen, they literally burst open, scattering seeds everywhere like nature’s confetti cannon.

The sesame plant isn’t just old—it’s ancient. Like, “older than your grandma’s cookie recipe” old. Historical records show that sesame was grown in Mesopotamia over 4,000 years ago, making it one of the oldest cultivated oilseed crops in the world.

In Egypt, sesame seeds were even found in tombs, possibly meant to nourish souls in the afterlife. Fast forward to today, and sesame remains a global staple—from Japanese goma shoyu to Middle Eastern halva to Mexican pan de acelga.
Where Does It Grow?
Sesame is a real sun worshipper. It thrives in tropical and subtropical climates, preferring long, hot summers and well-drained soil. Major producers include:

It’s drought-resistant and doesn’t mind poor soil much, which makes it a favorite among farmers in semi-arid regions.
