Culantro (eryngium foetidum) grows in a similar fashion to lettuce and can be perennial or annual depending on the climate grown.
Culantro is similar in aroma and flavor to cilantro, but they are not the same plant. It has long, serrated leaves and looks a bit like long-leafed lettuce. Culantro has a stronger flavor than cilantro and is therefore used in smaller amounts. Unlike cilantro, it can be added during cooking rather than afterward.
Culantro also dries well and retains flavour and colour.
It is native to Mexico and South America and as it is not well known outside Latin America.
At the peak of its growth, a culantro plant can be 1 foot tall and the leaves as much as 2 inches wide, and it will produce a blue flower if permitted to bolt. Culantro is a member Apiaceae family, which includes carrots, celery, parsley, and parsnip. Culantro is used as both a culinary and medicinal herb.
