Coriander
Coriander (Coriandrum sativum) is an annual herb in the family Apiaceae. It is also known as Chinese parsley or dhania, and in the United States the stems and leaves are usually called cilantro. All parts of the plant are edible, but the fresh leaves and the dried seeds (as a spice) are the parts most traditionally used in cooking.
Most people perceive the taste of coriander leaves as a tart, lemon/lime taste, but depending on ethnicity, 3–21% of people tested think the leaves taste like dish soap, linked to a gene which detects some specific aldehydes that are also used as odorant substances in many soaps and detergents.
Coriander is native to regions spanning from Southern Europe and Northern Africa to Southwestern Asia. It is a soft plant growing to 50 cm tall. The leaves are variable in shape, broadly lobed at the base of the plant, and slender and feathery higher on the flowering stems.
The flowers are borne in small umbels, white or very pale pink, asymmetrical, with the petals pointing away from the center of the umbel longer (5–6 mm) than those pointing toward it (only 1–3 mm long). The fruit is a globular, dry schizocarp 3–5 mm in diameter. Pollen size is approximately 33 microns.
