Coriandrum sativum aka Cilantro
Taxonomy
Coriander (Coriandrum sativum) or cilantro is an annual herb in the family Apiaceae. Most commonly used are the fresh leaves and the dried seeds in cooking and it has a tart, lemony-lime taste. However, individuals with a specific gene (OR6A2) may find the leaves taste like dish soap. It grows fast and has a bare stem which can reach between 16-28 inches (40-70 cm) tall, with broadly lobed and coarsely dissected basal leaves. Upper leaves have narrow linear segments. Flowers can be white or pink, forming complex umbrellas at the ends of their peduncles and their fruits are spherical ribbed. Cilantro blooms in June-July and ripens in July, August, and September. Interestingly, coriander and cilantro are actually the same plant, and its cousin is the culantro.
