How to Grow & Cook with Rau Ram (Vietnamese Coriander)
Rau Ram in Your Garden
Also known as Vietnamese cilantro or Vietnamese coriander, rau ram makes an unusual, and pretty, addition to your herb garden. (Its bright green leaves have maroon “inkblots.”) The plant is a perennial in warm, frost-free regions; buy organic seedlings from Mountain Valley Growers (mountainvalleygrowers.com).
Plant
Grow Vietnamese coriander seedlings in full or filtered sun (and afternoon shade where possible) in a large pot or in the ground. Rau ram grows fast—one plant may be all you need.
Care
Rau ram is thirsty, so keep the soil moist. If the plant stops producing new leaves in midseason, cut it back almost to the base to promote new growth. If it’s growing in a container, you might need to repot it into a bigger one—or divide it and replant in the same pot—a couple of times a season.
