The Vietnamese coriander is a perennial plant that grows best in tropical and subtropical zones in warm and damp conditions. It can grow up to 15 to 30 cm. In the winter or when the temperature is too high, it can wither. The top of its leaf is dark green, with chestnut-colored spots while the leaf's bottom is burgundy red. In Vietnam it can be cultivated or found in the wild.
