This Southeast Asian native is often used as a coriander substitute in Vietnamese cuisine. It adds a lemony coriander flavor to fresh salads, summer rolls, soups, and salads. In Zones 10 and 11, it can be grown outdoors in a moist, semishaded location as a perennial. Elsewhere, grow it as an annual or in a container to bring indoors over winter. The silvery leaves often develop a maroon blotch that makes the plant quite ornamental.
