Coriander (Coriandrum sativum)
You either love it, or hate it. Coriander, cilantro or dahnia, is an annual herb much used in Indian and Thai cuisine.
Apparently the love/hate relationship towards cilantro can be explained by genetics!
The plant is prone to bolting in very hot climates, and are best grown during the cooler months of spring and autumn. Reseeds easily.
