Eryngium foetidum - culantro.

Also known as Asian Coriander, Mexican Coriander, Culantro, Recao, Long Coriander, Perennial Coriander, False Coriander, Ngo gai, Spirit Weed, Fitweed.

It's the coriander you're having when you've given up on the Real Thing!

In a tropical climate, it can be a bit like mint - it also has a yearning to take over the world. In cooler climates, however, it is quite well-behaved.

Harvest leaves at any time once the plant is about 2-3 months old. The entire rosette can be cut off with a knife at the soil line. Leaves can be dried and retain their flavour better than Coriander. Seeds are contained in a cone-shaped, spiny seed head. Cut them off once they have opened and remove the seeds. The roots can be dried and ground to use like powdered coriander.

'In cooler climates, however, it is quite well-behaved.' In really cool climates it's dead!

Tee hee Flora! For the OP, I should have mentioned that it's a tropical plant, after all.
