Cilantro and coriander come from the plant species — Coriandrum sativum.
However, they are named differently in different parts of the world.
In North America, cilantro refers to the leaves and stalks of the plant. The word “cilantro” is the Spanish name for coriander leaves. Meanwhile, the dried seeds of the plant are called coriander.
Internationally, it’s a different story. Coriander is the name for the leaves and stalks of the plant, while the dried seeds are called coriander seeds.
Coriander enjoys a sunny position but appreciates a little shade during the hottest part of the day. Plants will run to seed more quickly if stressed by hot weather so this is important for leaf varieties.
You can also grow coriander successfully in pots or trays filled with a good multipurpose compost. Coriander plants have deep tap roots so pots need to be at least 25cm deep. Scatter seeds on the surface of the compost and cover, watering well. In a pot of 25cm diameter you can sow approx 5 seeds per pot.
Germination of coriander takes up to 3 weeks. Thin young plants to 20cm apart to allow them to grow to their full size. Water them in dry periods and ensure the soil never dries out. If flowers develop remove them immediately – this ensures the plants focus their energy on growing new leaves. Re-sow coriander every three weeks to ensure you have a continual supply during the summer. It is not normally necessary to feed coriander if the soil is well nourished. However is the plants appear to be suffering give them a liquid organic feed to perk them up.
Harvest the leaves when the plant is big and robust enough to cope. Pluck or cut each leaf off the stem or snip whole stems if necessary. Both the leaves and the stalks can be used.
If you are growing coriander for its seeds, wait until the flowers have died off before harvesting. Cut the stems and place the heads of the coriander in a paper bag, with the stems slicking out. Tie the stems and the bag together in a bunch and hang upside down in a cool, dry place. Wait for three weeks and then shake the bag. The dry seeds will fall out from the flowers and be ready in the bottom of the bag. Keep them in a dry place and re-sow the following spring.
