Coriandrum /kɔ.riˈan.drũː/

Common name: Cilantro · Coriander

Coriandrum A tiny genus of just two species of annual herbs in the carrot family, native to the Mediterranean and southwest Asia. Coriandrum sativum is the widely grown one, supplying fresh leaves known as cilantro, dried seeds sold as coriander, and edible roots used in Thai cooking. It grows quickly in cool weather but bolts to seed in heat, so gardeners often sow it in successive batches for a steady harvest.

Fun facts

  • The leaves are called cilantro and the dried seeds are called coriander — two spices from one plant.
  • Some people perceive cilantro as tasting like soap, a trait linked to the OR6A2 gene.
  • Cilantro bolts (flowers) quickly in heat, so it is often sown in succession for a steady harvest.
  • Coriander seeds have been found in ancient Egyptian tombs, including Tutankhamun's.

Common problems

    • Sow successionally every few weeks
    • Grow in light shade during summer
    • Choose slow-bolting varieties for summer
    • Wash aphids off with soapy water
    • Encourage hoverflies and ladybirds nearby
    • Sow thinly in free-draining soil
    • Avoid overwatering young seedlings
    • Thin seedlings to improve air flow
