Sawtooth Coriander (Eryngium foetidum) also called Thai Coriander, or Pointed Cilantro, Cilentro, Culantro, Thorny Coriander, Ngo Gai, Mexican Coriander, Phak Chee Farang, Daunketumbar Jawa, Chinese Coriander, and Long Leafed Coriander. It belongs to the Apiaceae, like the species listed above; is a biennial to 30-50cm, propagated by seed, sprinkled on top of the soil. Large oblong leaves form as a rosette.
I always encourage coriander lovers to grow a sawtooth and let it flower, when the seed is brown, cut off the stem, and there will be lots of seeds to get a whole row of plants growing. Thereafter, with the parent plant, always nip out the first signs of a flower appearing so the plant puts its energy into leaf production rather than into flowers and seed. If the plant flowers, the base leaves tend to become yellow and tougher in texture. This species tolerates hot, steamy, humid weather. In summer, watch that plants are given adequate water, if grown in full sun. Plants will also grow well in shade conditions. This species has been used in Indo-Chinese folklore medicine for a variety of ailments, from upper respiratory complaints to gastric upsets. In the kitchen, use the leaves in Thai, Vietnamese and Punjabi dishes. Try the chopped leaves in tossed salads, soups, sauces, vegetables, curries, dips and particularly fish dishes.... ... see How can I use HERBS in my daily life? for full text.
